Semi-aquatic predator found outside home in Brazil in first-of-its-kind sighting
On the outskirts of a town in northeastern Brazil, a semi-aquatic predator moved along the road near a house. The chance encounter turned out to be a first-of-its-kind sighting — and confirmation of an expert theory. Scientists received a report about a semi-aquatic snake found on the pavement of 'an urban area of the municipality of Areia, Paraíba,' in January, according to a study published May 21 in the peer-reviewed journal Check List. Intrigued by the accidental encounter, researchers took a closer look at the roughly 9-inch-long reptile and identified it as a juvenile Erythrolamprus mossoroensis, the study said. A photo shows the brown reptile. Erythrolamprus mossoroensis is a poorly known species of snake and a 'relative rarity in field studies,' according to a 2022 study. It has no English common name but is known in Portuguese as 'Cobra-d'Água' or 'Jararacuçu D'água,' names which roughly translate to 'water snake.' Erythrolamprus mossoroensis snakes are semi-aquatic predators, 'active both during the day and at night, with a diet consisting of amphibians and fish,' researchers said. Experts theorized that the species might live in the state of Paraíba because of the region's habitat and the species' presence in neighboring states, but no one had confirmed this — until now. The snake sighting in Areia, Paraíba, was the state's 'first confirmed record of (Erythrolamprus) mossoroensis,' researchers said. The team said their finding 'suggests that more specimens may be found in the region, reinforcing the need for further surveys to expand knowledge of this and other species in the area.' Paraíba is a coastal state in northeastern Brazil and a roughly 1,450-mile drive northeast from Rio de Janeiro. The research team included Élida Silva, José Robério Barboza Júnior, Mateus Dutra, Vanessa Barbosa, Frederico França and Rafaela França.

Regenerative hammerhead creature found creeping through kitchen in Madagascar
In Madagascar's densely populated capital city of Antananarivo, a slender creature with a wide head and the ability to regenerate copies of itself should it be cut apart, wriggled its way through someone's kitchen. The discovery of the nearly 10-inch-long Bipalium kewense — also known as the hammerhead flatworm — marked the first record of the highly invasive species in Madagascar, according to a May 21 study published in the journal Check List. While attempting to collect the flatworm, it broke into three separate segments — a common behavior called fragmentation exhibited by the species. It was eventually captured and removed from the country for further analysis, researchers said. The species, native to Indochina, can reproduce asexually and has been inadvertently transported through the global plant trade, making it a highly successful colonizer, researchers said. Despite being found in more than 78 countries around the world, it has scarcely been recorded in North Africa, according to the study. Researchers said two iNaturalist entries from 2024 may have featured Bipalium kewense in areas south of Antananarivo, but those observations are unconfirmed. According to the study, Bipalium kewense has also been confirmed for the first time in Egypt and South Africa. The research team included Romain Gastineau, Andrianjaka Ravelomanana, Remondah Rushdy Ramzy, Marcel Koken, Suzelyce Eva Soavolamanoro, Christian Otis, Brian Boyle, Delphine Gey, Leigh Winsor and Jean-Lou Justine.

‘Apex predators' photographed in mountains of Guatemala for first time. See them
In the mountains of a nature reserve in Guatemala, several 'apex predators' lived their lives almost completely unnoticed. Conservationists had long suspected the animals might use the park but didn't know for sure — until now. The Sierra de las Minas Biosphere Reserve spans a massive area of northeastern Guatemala and has varied terrain ranging from lowlands to cloud forests to peaks. Conservationists had identified the park as a Jaguar Conservation Unit, or an area 'capable of supporting viable jaguar populations,' according to a study published May 15 in the peer-reviewed journal Check List. But there was a catch: 'To date, no published records, museum specimens, or media evidence confirm the presence of jaguars and pumas' in the Sierra de las Minas Biosphere Reserve, researchers said. In hopes of tracking down these elusive wild cats, researchers spent nine years monitoring wildlife at the reserve with trail cameras. Their efforts paid off. In June 2015, one trail camera 'in a preserved clouded-forest fragment' recorded a jaguar walking by, the study said. The footage was grainy but clearly showed a jaguar passing near the camera then slowly vanishing into the trees. The sighting was also 'notable' for its elevation of about 7,360 feet, researchers said. As Guatemala's 'first high-elevation jaguar record,' the footage suggested 'the species' elevational and ecological range in the country may extend beyond previous knowledge.' Trail cameras also recorded 12 sightings of six pumas, or mountain lions, the study said. Photos show a few of these 'powerful and agile' felines. In one encounter, a mountain lion stops almost directly in front of the camera and seems to look into it. Other photos show the pumas walking past at a distance or briefly poking their heads into the frame. Jaguars and pumas live in the same regions and 'play a crucial role in maintaining ecosystem balance,' but their 'habitats have experienced significant range contractions and population isolation, mainly due to anthropogenic pressures such as habitat loss, fragmentation, and hunting,' the study said. 'The occurrence of jaguars and pumas across the (Sierra de las Minas Biosphere Reserve) provides critical insights into the distribution of these apex predators in the region' and can aid conservation efforts, researchers said. The research team included Luis Trujillo, Alejandro Mármol-Kattán, Cristina Abugarade, Adriana Rivera-Sandoval, Cristina Chaluleu-Baeza, Raquel Leonardo, Diana Mansilla, Allison Trinidad, Claudia Quijivix, Isabel Martínez, Cristina Escobar, Rocío Paz, Andrid Ramírez, Bárbara Escobar-Anleu, Rebeca Escobar and Rony Garcia-Anleu.

Slippery creature with ‘mask' found lurking on former prison island for 1st time
From a distance, an island just off the coast of Colombia looks like paradise. Luscious trees cover nearly 150,000 acres of protected land, now known as Gorgona National Natural Park. But when you get on the island, ruins of a prison sit reclaimed by the natural environment. Prior to 1984, the island was used as the site of a maximum security prison, likened to Alcatraz, reachable only by a two-hour boat ride and home to more than 1,000 prisoners throughout its history. A quarter of a century after its construction, however, an environmental and human rights campaign led to the closure of the prison and the island's establishment as a national park, according to the Colombian government. The park is now a stop for the more adventurous sightseers, or researchers cataloging the species that call the island home. During recent fieldwork as part of a project to survey the herpetofauna, or reptiles and amphibians, a research team found a small salamander lurking inside a rotting log, according to a study published May 12 in the peer-reviewed journal Check List. The log was on the edge of the forest, and surrounded by leaf litter and fallen debris, researchers said. Salamanders live in moist environments to keep their smooth, slippery skin wet in order to breathe, according to the Texas Wildlife Association. The animal inside was 'predominantly dark brown,' and covered in 'light blue spots,' according to the study. The head was lighter brown with a 'cream colored facial mask' that match the color of sporadic cream markings on the legs. The worm-like amphibian was identified as Oedipina villamizariorum, or Villamizar's worm salamander, but this brought more questions than answers for the research team. Villamizar's worm salamanders are known for 'elongated' bodies and 'cryptic habits' that make them 'especially difficult to detect in the field,' according to the study. They also have never been found on the island before. So far, the worm salamanders had only been found in Ecuador, but the species is externally very similar to another known species, O. complex, researchers said. Because the two species require genetic testing to confirm their separation, there is a chance that salamanders that were actually O. villamizariorum were misidentified as O. complex in the past, according to the study. Previous study of the Villamizar's worm salamander in Ecuador suggested the species be listed as 'critically endangered,' researchers said, citing an incredibly small geographic range. Now, with the extended range into Colombia, that could be reconsidered. 'Expanding the species' range to Gorgona National Natural Park represents an important conservation contribution. Nevertheless, the record remains limited to a single population isolated from the mainland and confined to only (about 10 square miles),' researchers said. 'This report underscores the need for further field surveys and research, particularly in areas where the species' presence remains unconfirmed.' Gorgona National Natural Park is located off the southern coast of Colombia in the Pacific Ocean. The research team includes Ana M. Saldarriaga-Gómez, Augusto Acosta-Peña, Damián S. Pardo, Darío Alarcón-Naforo and Esteban Betancourt.

Scuba divers find out-of-place sea creatures off Galápagos Islands. See them
Plunging into the crystalline waters of the Galápagos Islands, scuba divers swam along a coral reef and watched its ever-shifting marine life. Amid the hubbub, several unfamiliar sea creatures caught their attention — and for good reason. The out-of-place animals turned out to be first-of-their-kind sightings. Scientists with the Charles Darwin Research Station were doing some routine wildlife surveys at the Galápagos Marine Reserve off the coast of Ecuador in late 2023 and early 2024 when they encountered some intriguing fish, according to a study published April 28 in the peer-reviewed journal Check List. During dozens of scuba dives around the Galápagos Islands, researchers noticed eight fish species they'd never seen in the area before, the study said. One of these species was Acanthurus leucocheilus, 'a large surgeonfish,' that 'inhabits shallow, protected reef flats and slopes reefs' of Southeast Asia, researchers said and photos show. This fish on average is nearly 18 inches long. Researchers also saw Naso hexacanthus, or the sleek unicornfish, which 'is commonly found swimming above coral and rocky reefs.' The species is widespread throughout Southeast Asia but 'occasionally appears as a vagrant' along the coast of Central and South America. On another dive, researchers photographed a pair of Chaetodon punctatofasciatus, or spotband butterflyfish, yet another species typically found in Southeast Asia, the study said. 'It is often observed in pairs,' researchers said. Researchers noticed a pattern. Based on the timing of the sightings and the likely origin of the fish, they concluded that several of these fish had 'likely arrived during recent El Niño phenomena' when an ocean current that usually moves from South America toward Southeast Asia 'temporarily reversed' direction. El Niño events 'are often associated with the appearance of new discovered species in (Eastern Tropical Pacific) archipelagos,' the study said. But the new species' presence off South America 'is often temporary' and 'not necessarily' a long-term change in its distribution. 'It is possible that some of the species recorded here arrived during previous (El Niño) events, such as the one in 2015/16, but evaded detection,' the study said. Researchers also suggested that some of the newly recorded fish species could have arrived in the Galápagos Islands by drifting with marine debris, a method known as 'rafting.' Photos show a few of the other first-of-their-kind sightings, such as Gymnothorax porphyreus, or the Lowfin moray eel, and Kyphosus sectatrix, or the Bermuda sea chub. Researchers 'believe the number of vagrant arrivals is higher than currently recognised' and suggested further surveys and collaboration with other scuba divers. The research team involved William Bensted-Smith, Franklin Terán, Stuart Banks and Inti Keith as well as other citizen scientists and scuba divers.
