Officials say the non-native eels are unlikely to survive the winter, but experts caution that the serpent-like fish could still disturb the ecosystem

Conservation groups released Tasmanian devils in mainland Australia earlier this month, marking a major milestone in the process of restoring a species that has been missing for thousands of years.

For the First Time in 3,000 Years, Tasmanian Devils Return to Mainland Australia

The marsupial carnivores will roam the outback once again

A small-banded kukri snake seen with its head thrust inside the body of an Asian common toad. This snake does this to feed on its prey's internal organs, and, perhaps, to avoid the poisonous milky secretions that can be seen on the toad's back.

New Research

This Snake Slurps Organs of Living Toads in Grisly Feeding Strategy

Researchers say no other snakes are known to feed this way, adding that the snakes may feed this way to avoid toxins secreted from the toads’ backs

The results of a new study suggest crows are aware of their own sensory perceptions, a hallmark of what's called primary or sensory consciousness.

Do Crows Possess a Form of Consciousness?

New study suggests the corvids may join humans and some primates as one of the rare animals capable of having subjective experiences

This cave bear probably lived between 22,000 and 39,500 years ago, and researchers hope to get a better estimate with closer study.

A new genetic study confirms that the unique dogs, thought to be extinct in the wild, still exist outside of human care

The stomach of a 15-foot fossil ichthyosaur excavated in China contained this massive chunk of another large marine reptile. The ichthyosaur swallowed its prey shortly before it died and was fossilized.

The shocking size of the marine predator’s quarry may force paleontologists to rethink the marine reptile’s role in the Triassic ecosystem

New Research

This Marsupial Sabertooth Was No Killer Cat

Long fangs caused many to assume Thylacosmilus was a slashing predator, but new research suggests it was a scavenger with a preference for leftovers
