Deep sea creature washes ashore in South Africa village, photos show. ‘Very rare'

Miami Herald2 days ago

A sperm whale recently washed up on a beach in South Africa, a strikingly rare occurrence that hasn't happened in recent memory.
The massive marine animal stranded in the shallow waters off Langezandt Fisherman's Village — located about 130 miles southeast of Cape Town — on Friday, May 23.
Hours later, the whale was discovered dead on the shore, Jean Tresfon, a marine conservation photographer, wrote in a Facebook post.
Photos and videos posted by Tresfon show the behemoth lying on its side, partially embedded in the sand. Its mouth was agape — revealing a row of sharp teeth on its lower jaw — and blood could be seen on its scarred head.
'Really sad to see,' Tresfon wrote.
A video posted May 23 by the National Sea Rescue Institute, a South African non-profit, shows a whale floundering in the surf zone near the same beach.
'We are in contact with the DFFE Whale Disentanglement unit and at this stage there is nothing we or anyone else can do to assist,' the organization wrote before confirming in a follow-up post that the animal had died.
The incident was described as highly unusual.
'Sperm whale strandings in South Africa are very rare,' Tresfon wrote, 'which is unsurprising given that they are deep water whales which are seldom seen close to shore.'
Prior to this occurrence, the last documented stranding in South Africa took place in 2018 at Swartvlei Beach — about 215 miles east of Langezandt Fisherman's Village.
The largest toothed whale species on Earth, sperm whales are found in deep parts of every ocean, according to the National Oceanic and Atmospheric Administration (NOAA).
The animals — which can weigh up to 45 tons — dive up to 2,000 feet deep to hunt squid, sharks and other deep sea dwellers.
Threats to the species include entanglements with fishing gear, ocean contaminants and vessel strikes, according to NOAA.
And, while the circumstances of this stranding are unusual, cetacean strandings in general are a relatively common occurrence.
Globally, an estimated 2,000 whales and dolphins become stranded every year, with the majority being fatal, according to the Fish and Wildlife Foundation of Florida, a non-profit.

Rhody the robot helps Lake Ontario expedition to make a splash

May 30—OSWEGO — The National The National Oceanic and Atmospheric Administration's Deepwater Shipwreck Expedition at Lake Ontario wraps up today, and the two-week mission has created stunning results with the help of a remotely operated vehicle making its inaugural dives. "This has been a first of its kind expedition in a sanctuary," said Holly D. Pettus, deputy expedition leader. "We've used the University of Rhode Island's brand new ROV, Rhody, to document shipwrecks in order to construct awesome 3-D models." The ROV was developed by the URI Graduate School of Oceanography. The expedition set out on May 18 from Oswego aboard the 180-foot research vessel Lake Guardian, owned by the EPA. NOAA's Office of National Marine Sanctuaries and the University of Rhode Island's Ocean Exploration Cooperative Institute collaborated on the project. "It's been so cool to take Rhody on its maiden voyage and to see it in action for the first time," said expedition photographer and videographer Marley Parker. "I've been impressed by how reliable Rhody has been in this expedition and it's been amazing seeing it get in the water and doing its thing all day, every day." A U.S. National Marine Sanctuary, managed by NOAA, is a zone where the marine environment enjoys special protection. The Lake Ontario National Marine Sanctuary, designated last year, acts as an educational and cultural gateway between the Great Lakes and the Atlantic Ocean and protects culturally significant places, resources and artifacts integral to American history and the heritage of indigenous peoples. The sanctuary features a collection of 63 known shipwrecks and one known submerged aircraft, among the best preserved in the world, discovered over decades by local recreational scuba divers and shipwreck explorers. It ends just past Tibbetts Point Lighthouse in Cape Vincent, where Lake Ontario flows into the St. Lawrence River. Pettus and Parker, both from OCEI, spoke Wednesday during a live-streamed video of expedition highlights. They said 12 shipwrecks had been documented in the expedition, with a goal of 14. They were confident they would reach the goal by the end of the expedition today. "I've been so amazed by this team," Parker said. "When I first looked at the expedition plan and saw that it had 14 shipwrecks in two weeks, I thought there was no way we could do that. I've worked on a lot of ships and rarely worked on a team as tenacious as this one — getting after it every day." The expedition is a 24-hour operation, Parker added. "During the day, our ROV team is up early and getting the ROV in the water, first thing. We often do multiple dives in one day. They close up shop in the evening and then our mapping team comes online. The team has been imperative to making this expedition as successful as it's been. They have identified many new, previously undiscovered wrecks within this sanctuary and we've been able to pinpoint their locations with survey maps." Pettus said that with a team of skilled divers, it could take more than five days to explore and document a shipwreck. "Yesterday, we completed four dives," she said. "We are all systematic and have gotten into a great rhythm, and that's allowed us to move pretty quickly." The expedition targeted shipwrecks not accessible to most SCUBA divers. "The typical recreational SCUBA diver can only go to about 120 feet," Pettus said. "A lot of the wrecks we've been going to are over 200 or 300 feet and sometimes much deeper." "Not to mention how much more efficient and quickly Rhody can make these maps and imagery happen, compared to humans," Parker said. Expedition technology, Pettus said, has rapidly advanced in the past two decades. Software developments have allowed the creation of 3-D models of shipwrecks with stunning accuracy. Another promising element is the ability to have Rhody remotely operated. For example, during it's Lake Ontario mission, it was controlled at one point by Jake Bonney at the University of Rhode Island. "In the future, it's going to look a lot different in another 10 or 20 years from now," Pettus said. "We're going to see a massive increase in remote piloting. That opens up all kinds of opportunities." Pettus said Rhody could be used for emergency response or to simply check out underwater architecture. "It's an instrument that can easily mobilize," Parker said. "I'm excited to look back years from now after Rhody has done multiple projects and maybe even some emergency response work and to look back and think, 'I remember when Rhody was brand new and on its first expedition.'" The Ocean Exploration Cooperative Institute team will return home to Rhode Island after today. "Meanwhile, the marine archaeologists will spend hundreds and hundreds of hours reviewing and closely examining all of the data we've captured, because they are basically hunting for clues in the footage of what and where to find artifacts within these vessels that could help them to glean information about the exact identifications of some of these wrecks," Parker said. "This baseline information will help protect and preserve these artifacts on the bottom of the (lake) floor," Pettus said. "The small but mighty team at NOAA's office of Marine Sanctuaries are working hard to make sure all of these wrecks are protected, preserved and the ones that can be accessed will be properly buoyed, so the public can come out and enjoy these things as well."

National Hurricane Center eyeing tropical wave as season nears, here's where

The official start of the 2025 Atlantic hurricane season is just two days away and so far, the tropics are quiet. As of Friday, May 30, the National Hurricane Center is tracking one tropical wave moving into the Caribbean, but no tropical cyclone activity is expected for the next seven days. On the other side of Mexico, Tropical Storm Alvin, the first tropical storm in the Northern Hemisphere in the 2025 hurricane season, is sending swells to the coasts of west-central and southwestern Mexico and the southern Baja California Peninsula, but it expected to unravel quickly, the NHC said. 1st tropical storm of season: Tropical Storm Alvin forms in Pacific: See projected path, spaghetti models The 2025 Pacific hurricane season began on May 15, two weeks earlier than the Atlantic season, which officially begins Sunday, June 1. ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location The National Oceanic and Atmospheric Administration released its prediction for the 2025 Atlantic hurricane season on Thursday, May 22, predicting an above-average season, with 13 to 19 named storms and six to 10 hurricanes. The first named storm of the 2025 Atlantic season will be Andrea. Here's the National Hurricane Center's daily outlook as of 6 a.m. on Friday, May 29. ➤ Track all active storms The National Hurricane Center said there are no tropical disturbances in the Atlantic basin and no tropical cyclone activity is expected during the next seven days. Forecasters are tracking one tropical wave: The axis of a tropical wave is near 68W south of 15N, southeast of Puerto Rico, moving westward at 15 to 20 kt. Limited convection is noted with this wave. The Atlantic basin consists of the northern Atlantic, Caribbean Sea and Gulf of America. NOAA changed its naming convention for the Gulf of Mexico after the U.S. Geological Survey changed the name on U.S. maps per President Donald Trump's order. Forecasters urge all residents to keep an eye on the tropics and to always be prepared. ➤ Creating hurricane supplies kit important, but what if money is tight? Tips, resources to help NOAA is predicting there is a 60% chance of an above-normal season, a 30% chance of a near-normal season and a 10% chance for a below-normal season. ➤ NOAA predicting above-average 2025 Atlantic hurricane season. What can Florida expect? Forecasters predict: Named storms: 13-19 Hurricanes: 6-10 Major hurricanes: 3-5 A major hurricane is a Category 3 storm or higher, with maximum sustained winds of at least 111 mph. Tallahassee meteorologist Ryan Truchelut, who forecasts under WeatherTiger, is predicting landfall risks as near to slightly above normal this year due to closer-to-average sea temperatures in 2025. Truchelut looks more at impact than the Atlantic basin as a whole. So far, he's predicting 65% odds of an above normal season: Tropical storms: 16-20 Hurricanes: 7-9 Major hurricanes: 3-4 Tracking the storms: New study finds this company most accurate for hurricane predictions. Is it right? A tropical wave is a system of low pressure that moves westward across the tropics. Waves can lead to the formation of tropical cyclones, under the right conditions, according to the National Weather Service. The majority of tropical cyclones develop out of tropical waves, which also are called easterly waves, according to NOAA. AccuWeather Senior Meteorologist Dan Kottlowski said 85% of all tropical storms can trace their origins to tropical waves. "If a tropical wave survives its journey westward, it will find increasingly warm waters and moist air as it approaches the Lesser Antilles, a group of islands in the Caribbean Sea," AccuWeather said. The Atlantic hurricane season starts June 1 and ends Nov. 30. Since 2003, there have been 15 tropical cyclones that have formed before June 1. Eleven of those storms formed in May. There have even been occasions when a tropical cyclone has formed in January. Here's a look back at a few of the early storms: Jan. 16-17, 2023: Unnamed subtropical storm. May 22-23, 2021: Tropical Storm Ana. May 16-19, 2020: Tropical Storm Arthur. May 27-28, 2020: Tropical Storm Bertha. May 20-21, 2019: Subtropical Storm Andrea. May 25-31, 2018: Tropical Storm Alberto. April 19-21, 2017: Tropical Storm Arlene. Jan. 12-15, 2016: Hurricane Alex May 27-June 4, 2016: Tropical Storm Bonnie May 8-11, 2015: Tropical Storm Ana. May 19-22, 2012: Tropical Storm Alberto. May 26-30, 2012: Tropical Storm Beryl. May 31-June 1, 2008: Tropical Storm Arthur. May 9-11, 2007: Subtropical Storm Andrea. April 20-24, 2003: Tropical Storm Ana. The first named storm of the 2025 Atlantic hurricane season will be Andrea. Since 2003, Andrea has appeared twice in May, including the last year the name appeared in 2019. May 9-11, 2007: Subtropical Storm Andrea May 20-21, 2019: Subtropical Storm Andrea The World Meteorological Committee maintains six lists of hurricane names in the Atlantic basin and separate lists for the Pacific basin. There are 21 names on each list. The six lists of names are used on a rotating basis, so names from the list used in 2025 will appear again in 2031, unless a name is retired. A nation hit hardest by a devastating storm can request its name be removed because use of the name again would be insensitive. Beryl, Helene and Milton were retired from the list used last year and were replaced with Brianna, Holly and Miguel. Tropical outlooks are issued every day by the National Hurricane Center from May 15 through Nov. 30. The outlooks come out at 8 a.m., 2 p.m., 8 p.m. and 2 a.m. ET. ➤ Where can I find Hurricane Center's tropical outlooks? ➤ Where will Hurricane Center issue advisories? A map highlights "significant areas of disturbed weather and their potential for development during the next seven days," said Larry Kelly, hurricane specialist with the National Hurricane Center, in an email. Contained in the outlook are the probabilities an area could develop into a tropical cyclone over the next 48 hours and seven days: A low probability of development ranges from 0-30% (designated in yellow) A medium probability of development ranges from 40-60% (designated in orange) A high probability of development ranges from 70-100% (designated in red) "The hatched areas on the graphic represent the potential formation area during the forecast period. It is important to note that it is not a forecast track and just a formation area," Kelly said. ➤ In a rush? 15 things you should know before 2025 hurricane season arrives "The tropical weather outlook provides forecasts on areas of disturbed weather that could develop into tropical cyclones," Kelly said. "It highlights the location, movement, and development potential of these systems over the next two to seven days. "This information is important for early preparation and awareness during hurricane season so you can be prepared for the hazards that systems can bring, including storm surge, flooding, strong winds, tornadoes and hazardous marine and beach conditions." Although many people search Google for an answer to the question "When is Florida hurricane season?" there actually is no such thing. The Atlantic hurricane season starts June 1 and lasts until Nov. 30. Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said, so storms can form before and after those dates. Tropical storms and hurricanes that develop in the Atlantic basin do impact the U.S., from the Gulf Coast and Florida north into Canada. The Atlantic basin consists of the northern Atlantic, Caribbean Sea and Gulf of America. Predictions released as of May 13 predict an above-normal number of named tropical systems, ranging from: Named storms: 13-21 Hurricanes: 7-10 Major hurricanes: 3-5 ➤ Florida is No. 1. That's not good when it comes to hurricane season predictions. See forecast Named storms: 14 Hurricanes: 7 Major hurricanes: 3 The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center. Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the Atlantic basin. To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA said. Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated: : for storms in the North Atlantic, central North Pacific, and eastern North Pacific. : for storms in the Northwest Pacific. : for storms in the South Pacific and Indian Ocean.

2.2 million-year-old teeth reveal secrets of human relatives found in a South African cave

When you buy through links on our articles, Future and its syndication partners may earn a commission. Small pieces of tooth enamel from deep in a South African cave have begun to reveal secrets held for 2 million years by a distant human relative, a new study finds.. Archaeologists recovered teeth from four members of the species Paranthropus robustus, a two-legged human relative who lived between 1.8 million and 1.2 million years ago, from Swartkrans, a fossil-bearing cave in Africa's Cradle of Humankind World Heritage site. Using cutting-edge techniques that can analyze fossils' amino acid sequences, the researchers were able to determine the sex of the individuals and discovered surprising genetic variation that could point to the existence of a previously unknown species. These techniques are part of the field of proteomics, or studying sets of preserved proteins — a relatively new area of science that is shedding much-needed light on the evolution of early hominins, a group that includes humans and our closest relatives. "Figuring out the human family tree using proteins is the goal," Claire Koenig, a postdoctoral researcher at the University of Copenhagen and co-author of a study published Thursday (May 29) in the journal Science, told Live Science in an email co-written with lead author Palesa Madupe and co-author Ioannis Patramanis. But currently "our ability to distinguish between different species is limited by the small number of different proteins present in enamel." Although DNA has been recovered from ancient skeletons in Africa, so far that technique has only successfully worked on hominin material dating to no more than 20,000 years ago — well within the lifetime of our own species, Homo sapiens — because DNA degrades quickly in that environment. To get at the roughly 6 million-year history of hominin evolution, analysis of the harder and more stable tissue of dental enamel is needed. In the new study, an international team of researchers led by Madupe employed paleoproteomic analysis to move beyond the limits of ancient DNA and understand the genes of four hominins who lived around 2 million years ago. "Proteomics is inherently a destructive technique, but we take great care to minimize impact, especially when working with rare or precious specimens," Koenig said. Related: In a 1st, ancient proteins reveal sex of human relative from 3.5 million years ago The researchers focused their proteomic analysis on four P. robustus individuals who likely all died around the same time. They were able to identify AMELY-specific peptides, which are found in the tooth enamel of males, in two individuals. The other two individuals had a high AMELX intensity, meaning they were likely female. Correctly determining the sex of a fossil is important in paleoanthropology because most hominins are sexually dimorphic, with males being, on average, larger than females. Experts therefore expect that any species will have some larger and some smaller individuals. But Madupe and colleagues discovered a surprising result: one P. robustus individual who was thought to be female, based on tooth size and shape, was actually male, based on proteomic data. "Our results thus indicate that measurements of dental size are not necessarily accurate for correct sex estimation," the researchers wrote in the study. Since sex alone could not explain the differences in the appearance of P. robustus, the team investigated whether the diversity they were seeing could be the result of different groups or species they didn't know about, or the result of interbreeding, as P. robustus overlapped in time with australopithecines and early members of the Homo genus. The researchers found a couple amino acid sequence positions that varied among the P. robustus specimens they examined, and that were different from the amino acid sequences seen in present-day humans, Neanderthals and Denisovans. This analysis revealed that one of the individuals — SK-835, whose molecular sex and morphological sex did not match up — was more distantly related to the other three individuals than they were to each other. "It would be premature to classify SK-835 as a member of the newly proposed Paranthropus [capensis] taxa," Koenig said, but it remains a possibility that the amino acid difference reflects its position in a different species than the rest. It could also be explained, however, by microevolution at different sites, study co-author Rebecca Ackermann, a biological anthropologist at the University of Cape Town, told Live Science in an email. "We need to analyse more Paranthropus material from different sites to get a better handle on the variation within southern African Paranthropus," she said.

Koenig expects that further methodological developments will be beneficial, including less invasive methods such as acid etching to remove an extremely thin layer of dental enamel, and the development of faster and more sensitive protein-sequencing instruments. "It remains to be seen, for example, whether or not we can molecularly tell apart a Paranthropus robustus from an Australopithecus africanus," Koenig said, "because these species are closely related and therefore their proteins are going to look very similar."
