Infamous 'death roll' almost universal among crocodile species

The iconic "death roll" of alligators and crocodiles may be more common among species than previously believed, according to a new study and coauthored by a researcher at the University of Tennessee, Knoxville.

Contrary to popular belief, crocodiles can't chew, so they use a powerful bite coupled with a full-bodied twisting motion -- a death roll -- to disable, kill, and dismember prey into smaller pieces. The lethal movement is characteristic of both alligators and crocodiles and has been featured in numerous movies and nature documentaries, according to Science Daily.

Don't let the cat out if you want to stay disease-free, as researchers warn that outdoor roaming pet cats are three times more likely to carry infections

If you think letting your cat out to play is good for its health think again as the chances are it's also picking up contagious diseases, according to Daily Mail.

Domestic cats that roam freely outdoors are three times more likely to pick up an infection that develops into disease than indoor-only cats, a study has found.

Such infections include the parasite Toxoplasma Gondii, which can spread to cat owners and has been linked to depression and schizophrenia in humans.

Outdoor cats can also pick up roundworms, which may be passed on to children, causing fever, stomach pain and, in rare cases, seizures.

Meet the monstrous giant sea spider that grows legs like 'SWISS CHEESE' that help it breathe in warming waters

Nightmarish giant sea spiders breathe through holes in their legs that get bigger as they grow, allowing them to take in more oxygen, a new study has found.

Scientists have wondered for decades why marine animals that live in the polar oceans and the deep sea can reach giant sizes there, but nowhere else, according to Daily Mail.

One leading theory is that animals living in extreme cold can grow to giant sizes because their metabolisms are very slow.

Wolves return to Netherlands after 140 years

The Netherlands has its first resident wolf population in 140 years, according to ecologists.
Wolves were hunted out of many European countries over a century ago but have gradually been migrating back across the continental mainland.
Occasional wolf sightings have been made in the Netherlands since 2015, according to BBC.
But these animals were previously thought to be animals that had crossed over temporarily from Germany and would subsequently return there.

Ancient, four-legged whale with otter-like features found along the coast of Peru

Cetaceans, the group including whales and dolphins, originated in south Asia more than 50 million years ago from a small, four-legged, hoofed ancestor. Now, researchers reporting the discovery of an ancient four-legged whale -- found in 42.6-million-year-old marine sediments along the coast of Peru -- have new insight into whales' evolution and their dispersal to other parts of the world, according to Science Daily.

The presence of small hooves at the tip of the whale's fingers and toes and its hip and limbs morphology all suggest that this whale could walk on land, according to the researchers. On the other hand, they say, anatomical features of the tail and feet, including long, likely webbed appendages, similar to an otter, indicate that it was a good swimmer too.

"This is the first indisputable record of a quadrupedal whale skeleton for the whole Pacific Ocean, and the most complete outside India and Pakistan," says Olivier Lambert.
