Elusive scaly creature with blue mouth and green blood is a new species. See it

In the mountains of Papua New Guinea, researchers encountered a clownish creature perched on a log in a fern meadow, basking in the sun.
With its short, blunt snout and unique checkerboard pattern, this scaly creature — a skink — wasn't like the other 35 related species that call the mountains home.
This distinctive and elusive variety turned out to be a new species, belonging to a family of skinks known for having green blood, according to an April 15 study published in the peer-reviewed journal Zootaxa.
Since that 2009 sighting in the mountain meadow, Prasinohaema scurrula, or the scurrula skink, has scarcely been seen despite years of 'intensive surveys,' researchers said.
The species has been observed in three mid-mountain locations in central New Guinea at elevations between about 7,100 feet and 9,500 feet, according to the study.
Researchers observed a single skink at two of the three sites, one of which was in a tree, leading them to hypothesize the species may live in the forest canopy, making surveys more difficult and sightings rare, according to the study.
The skink is described as having a kite-shaped head, a blue mouth, and a 'robust' body covered in glossy scales with light and dark brown bands that create a checkerboard pattern down its back.Researchers said the pattern resembled the costumes historically worn by clowns and jesters, according to researchers. The name scurrula means small clown in Latin, according to the study.
The species' green blood, a characteristic of the Prasinohaema genus, is the result of 'extremely high concentrations of biliverdin,' according to the study. Biliverdin is a green pigmented compound in blood, also responsible for the greenish tint to bruises in humans.
While the scurrula skink is rarely seen and 'poorly understood', researchers said the species has an 'extensive suitable habitat' and 'no major current threats,' and should be given a status of Least Concern with The International Union for Conservation of Nature.
The research team included Alex Slavenko, Glenn Shea, Stephen Richards and Paul Oliver.

Rare and ‘secretive' snake — that can climb trees — found in Vietnam rainforest

In the protected, undisturbed limestone forests of central Vietnam, a 'secretive' creature emerged at nightfall. In a scene framed by the opening of a karst cave, the 20-inch black and cream-colored banded snake targeted an unknowing skink. It is an adept hunter, able to move swiftly over rocky terrain and even climb trees. Researchers have now confirmed the snake, discovered in Phong Nha-Ke Bang National Park in the Northern Annamites, is a new species called Lycodon calcarophilus, or the Limestone wolf snake, according to a study published Aug. 12 in the peer-reviewed journal Zootaxa. The mountainous rainforest region where the limestone wolf snake was found is considered to be one of Vietnam's 'most significant protected areas' in terms of reptile and amphibian diversity, according to the study. 'Numerous studies have emphasised the remarkable species richness' and the large number of species that exist only in the karstic region and nowhere else in the world, researchers said. The new species is described as being relatively small compared to related species. Its blackish-brown body is 'laterally compressed' with between 19 and 25 'pinkish-cream' colored bands, researchers said. The new species has a head that is angular, slightly flattened, and distinct from the rest of its body, according to the study. Researchers said the species is 'likely rare, as suggested by the very limited number of observations.' The team encountered just six during their fieldwork. However, the limestone wolf snake is likely to be found in 'limestone massifs outside the park boundaries, where forest habitats are increasingly threatened by anthropogenic activities.' The discovery of the new species brings the known number of Lycodon species in Vietnam to 17, according to researchers. Researchers recommend listing the new species as data deficient on the International Union for Conservation of Nature's Red List until more field surveys can determine its threatened status. The research team included Gernot Vogel, Andrey M. Bragin, Nikolay A. Poyarkov and Tan Van Nguyen.

Fish Bone or Cancer? 80-Year-Old's Perforation Case

Key Takeaways An 80-year-old man presented with progressive lower left-quadrant abdominal pain. Imaging studies identified a mass adjacent to the sigmoid colon, with features suggestive of an abscess, although no definitive foreign body was detected preoperatively. Surgical exploration revealed a sigmoid colon perforation associated with a sharp foreign object, which was later confirmed to be a fish bone. Histopathological examination revealed an inflammatory response without evidence of malignancy. The case reported by Daniel Herrera Hernández, MD, and colleagues from the Hospital General Regional No. 1 Instituto Mexicano del Seguro Social, Tijuana, Mexico, highlighted a rare cause of intestinal perforation. The Patient and His History The patient had a medical history of diabetes mellitus and hypertension. There was no prior surgical history or screening colonoscopy. He reported a 12-day history of lower left-quadrant abdominal pain, progressively worsening to become intolerable, prompting emergency admission. Findings and Diagnosis On presentation, the patient was stable but exhibited abdominal distension and tenderness on palpation of the left hemiabdomen, without signs of peritoneal irritation. Laboratory tests showed leucocytosis of 20,800/μL (4000-11,000), neutrophils at 65.1% (40%-70%) of total leukocytes, and a serum creatinine of 1.0 mg/dL (0.6-1.2). Abdominal and pelvic CT scans revealed a mass adjacent to the descending colon with peripheral enhancement dependent on the colonic wall, extending into the muscular layer, suggestive of an abscess, as well as a small radio-opaque object in the middle of the phlegmon, supportive of a foreign body. Adjacent fat stranding and free fluid were observed in the left iliac fossa. The patient underwent exploratory laparotomy, revealing a colonic perforation at the sigmoid colon with firm adhesions to the abdominal wall. A sharpened foreign body, approximately 2 cm in length, was found at the adhesion site, which was the cause of the perforation. No diverticula were identified in the colon. Left hemicolectomy with transverse colon terminal colostomy was performed. Postoperative recovery was uneventful under antibiotic therapy with meropenem and metabolic management. The patient was discharged on postoperative day 5 with clinical improvement. The histopathology report indicated chronic inflammation with no evidence of malignancy. Discussion 'Intestinal perforation by a fish bone in the colon is a rare complication that poses diagnostic challenges. It requires a high index of suspicion from surgeons or emergency physicians. In patients with risk factors, such perforations can resemble tumours with abscess formation or perforation secondary to malignancy,' the authors wrote.

These tarantulas may have evolved huge genitalia to fend off bloodthirsty females

Researchers have uncovered a new tarantula genus called Satyrex where males may have evolved longer sex organs to avoid getting eaten by fierce females. A female from the species Satyrex ferox is pictured above. Photograph By Premysl Fabianek When scientists discover a new species, they usually name it after the creature's most notable characteristic. So why did a group of scientists recently name a newly discovered genus of tarantulas after satyrs, the famously well-endowed half-goat men from Greek mythology? Like a satyr, the new species have massive members that dwarf those of all other tarantulas, scientists explain in a study published last month in the journal ZooKeys. Females in this genus are extremely aggressive, so scientists speculate that their males evolved ginormous genitals to keep a safer distance during mating. 'New species are found quite regularly, but finding large-sized spiders with such bold behavior and such unique features, that doesn't happen every day,' says Alireza Zamani, an arachnologist at the University of Turku in Finland and co-author of the new find. 'There's a lot that we don't know about our planet.' Female tarantulas (Satyrex somalicus pictured) are known to eat males after sex. Photograph By Premysl Fabianek Chowing down on their mates may give females (Satyrex arabicus pictured) an energy boost to raise a clutch of eggs. Photograph By Mohssin Fageeh Last year, Zamani was poring over old records of tarantula sightings when he noticed something strange. The scientific record, the citizen science platform iNaturalist, and even social media sites were all teeming with reports of tarantulas with massive sex organs in the Arabian Peninsula and the Horn of Africa. Tarantulas, like all spiders, don't have penises; they have palps. Located near the spider's mouth, palps are leg-like appendages that are used for everything from mating to feeding. Males have structures on their palps known as palpal bulbs. The bulbs look like boxing gloves and function like syringes. When it's time to mate, males deposit sperm onto one of their webs and then transfer it to their papal bulbs. Once they have a female in their grasp, they will insert one of their palps into the female's genital opening and deposit their sperm. While palp size varies species to species, the palps that Zamani was seeing were unlike any he had seen before. He contacted researchers in Africa and the Middle East, and eventually got his hands on eight preserved specimens, their impressive palps intact, as well as photos and videos of them in the wild. By studying their structure and DNA, Zamani and his colleagues were able to determine that these tarantulas not only belonged to four new species but also comprised an entirely new genus. They dubbed this new genus Satyrex, which is a combination of Satyr and the Latin word rēx, meaning the spiders in this genus live underground and are 'highly defensive and highly aggressive,' Zamani says. The most aggressive of the bunch is Satyrex ferox. This spider, which is the largest in the genus, has palps that can reach a whopping five centimeters (nearly two inches), making them nearly as long as its longest legs. Their name comes from the Latin word for "fierce." According to Zamani, this spider will assume a defensive posture at the slightest disturbance, raising its front legs and rubbing them together to make a hissing sound. The tarantula tango The researchers speculate that male members of Satyrex may have evolved their huge palps to avoid getting attacked and eaten by females during sex. For many tarantulas, mating is a deadly duel. During such bouts, males strive to inseminate and escape, while females fight to make a meal of their would-be suitors. (See a rare video of tarantula mating.) In nearly all tarantulas, including the new Satyrex species, males have evolved hooks on their front legs that they use to lock the female's fangs in place during mating to stop her from biting them. While these little hooks work for most tarantulas, Zamani suspects they alone are unlikely to protect members of Satyrex from their feisty females. Having huge palps may help male Satyrex spiders maintain a safe(ish) distance from females during mating, he says. 'I think it's a fascinating hypothesis that is very testable,' says Chrissie Painting, a behavioral ecologist who studies mating systems at the University of Waikato in New Zealand. Painting, who was not involved with the study, says these spiders may be in the midst of an evolutionary arms race, with females evolving to become more aggressive in order to snag a snack that can sustain them in motherhood and males evolving better means of mating with them without getting eaten. While more research is needed to confirm this, Painting says, sexual cannibalism is a strong driver of evolution. In other spider species with sexual cannibalism, Painting points out, males have evolved the ability to transfer sperm extremely quickly to reduce their chances of getting eaten while getting it on. (Meet the tarantula named after Johnny Cash.) Having longer leg-like genitals may help male Satyrex tarantulas (Satyrex arabicus shown) keep a safe distance from feisty females during sex. Photograph By Mohssin Fageeh A broader web of spider diversity Zamani and his colleagues were surprised that the spiders they described in this study had gone undiscovered for so long. But our planet is home to over 1,000 species of tarantulas, and many have yet to be found. 'The reality is that the vast majority of Earth's biodiversity remains undocumented,' he says. When it comes to the range of weird spiders yet to be discovered, these tarantulas may just be the tip.
