Scientists have confirmed the presence of a whale off New England that went extinct in the Atlantic Ocean two centuries ago. It is an exciting discovery, but one they said illustrates the impact of climate change on sea life. Researchers with the New England Aquarium in Boston found the gray whale while flying 50 kilometres south of Nantucket, Massachusetts in the US on 1 March. The whale, which can weigh up to 27,215 kilograms, typically lives in the northern Pacific Ocean. This particular whale may have been in Atlantic waters for a couple of months as scientists believe it was spotted off t...

A volcano on an island in the Galápagos could threaten the survival of the last known survivor of a species of giant tortoise. The La Cumbre volcano on Fernandina island began erupting on Saturday night, lighting up the nighttime sky as lava tumbled down its sides toward the sea. Fernandina is home to Fernanda, a giant tortoise a lone female was discovered living on an isolated vegetation patch on the island in 2019. Read the full story of Fernanda's discovery here.

By Maxwell Radwin MEXICO CITY — The trafficking of valuable fish bladders found in Mexico appears to be on the rise online and on social media, and it’s having a ripple effect on other endangered species in the region. Dried swim bladders, or “maw,” of totoaba, an endangered fish found in the Gulf of California in northern Mexico, are being increasingly trafficked on digital platforms, according to a report from the Environmental Investigation Agency (EIA), an environmental NGO. The demand for totoaba has impacted other animals that get caught in the same gillnets, most notably vaquitas, the s...

A new dinosaur-like species has been uncovered in Scotland, giving palaeontologists a precious insight into animal life in the Middle Jurassic. Researchers from the UK’s Natural History Museum first noticed a few bones sticking out of a boulder during a field trip to the Isle of Skye in 2006. That fossil has now been revealed as a new species of pterosaur, named ‘Ceoptera evansae’. These flying reptiles - pterosaur literally translates as ‘wing lizard’, like helicopter means ‘spiral wing’ - existed from the Late Triassic to the same extinction event that killed the dinosaurs around 66 million ...

Scientists hope that the first pregnancy of a rhinoceros after an embryo transfer could pave the way to save the nearly extinct northern white rhino subspecies. The method was tested in another rhino subspecies, with researchers successfully creating a southern white rhino embryo in a lab. Scientists and veterinarians transferred two southern white rhino embryos into a surrogate mother at a conservancy in Kenya and confirmed a pregnancy of 70 days. Successful trial of 'sperm-injecting robots' offers hope of low-cost alternative to traditional IVFThe success allows them to "now safely move to t...

An ancient species of great ape was likely driven to extinction hundreds of thousands of years ago when climate change put its favourite fruits out of reach during dry seasons, according to a new study. The species Gigantopithecus blacki, which once lived in southern China, represents the largest great ape known to scientists - standing 3 metres tall and weighing up to 295 kilograms. But its size may also have been a weakness. “It's just a massive animal - just really, really big,” says Renaud Joannes-Boyau, a researcher at Australia's Southern Cross University and co-author of the study publi...

Humans have wiped out around 1,400 bird species - double the amount previously thought - a recent study has found. This amounts to one in nine or 12 per cent of species being lost over modern human history, according to the UK Centre for Ecology & Hydrology (UKCEH). Deforestation, overhunting and the introduction of invasive species are some of the main threats introduced by humans since the Late Pleistocene period around 130,000 years ago. “Humans have rapidly devastated bird populations via habitat loss, overexploitation and the introduction of rats, pigs and dogs that raided nests of birds ...

Paris (AFP) - For species classified as "extinct in the wild", the zoos and botanical gardens where their fates hang by a thread are as often anterooms to oblivion as gateways to recovery, new research has shown. Re-wilding what are often single-digit populations faces the same challenges that pushed these species to the cusp of extinction in the first place, including a lack of genetic diversity. But without conservation efforts, experts say, chances of these species surviving would be even smaller. Since 1950, nearly 100 animal and plant species vanquished from nature by hunting, pollution...

Washington (AFP) - Ever since the movie Jurassic Park, the idea of bringing extinct animals back to life has captured the public's imagination -- but what might scientists turn their attention towards first? Instead of focusing on iconic species like the woolly mammoth or the Tasmanian tiger, a team of paleogeneticists have studied how, using gene editing, they could resurrect the humble Christmas Island rat, which died out around 120 years ago. Though they did not follow through and create a living specimen, they say their paper, published in Current Biology on Wednesday, demonstrates just ho...
