Most animals that hibernate during cold winter months have thick coats of fur or layers of fat to protect them. However, the Rana sylvatica species of the wood frog that can be found in Alaska and the Arctic Circle has neither. Therefore this tiny amphibian has adapted by freezing and thawing itself depending on the external temperature.

Researchers have long suspected that hippos evolved from a family of plant-eating, semi-aquatic mammals called anthracotheres. The ancient animals that roamed freely all the way from North America to Asia inhabited Earth about 40 million years ago. However, scientists could never verify the theory since the only fossils of ancient hippos discovered thus far, dated back just 15 million years. Now thanks to Fabrice Lihoreau, there is finally some proof.
While every dog owner knows that their pooch can discern their moods perfectly, scientists have always been a little skeptical. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some tangible evidence.
Seadragons may sound like mythical creatures from a fairy tale, but these tiny fish that are close cousins of seahorses and pipefish do exist. Found in the coastal waters off southern and western Australia, the gorgeous creatures that feed off tiny crustaceans, plankton, and larval fishes, do not have teeth or a stomach. They therefore, have to eat constantly and are always scouring the oceans in search of prey.
For over two decades, marine biologists have been listening to the songs from a whale that resides in the North Pacific. However, they have never heard a fellow mammal responding. That's because, unlike most whales that croon at a frequency of 15-20 hertz, this one sings at high pitched 52 hertz. As a result, this poor animal has never had a friend and, therefore, become known as the "world's loneliest whale!"
An underwater diver filming the beautiful coral in the Caribbean captured a rare sight - a perfectly camouflaged octopus emerging from its hiding place with its skin transforming from the dull green of the coral to a beautiful sky blue. Jonathon Gordon says that he was just trying to get a closer look at an unusual shell and had no idea that the creature was there, until he was just about a meter away.
The appearance of large jellyfish blooms is often met with dismay. That's because though these floating blobs of gelatin are essential for the ecosystem and an important food source for certain marine animals, they are very destructive. In addition to inflicting painful stings, large groupings of the invertebrates frequently clog commercial fishing nets and even cause power stations to shut down.
February 2nd was Groundhog Day. This meant that woodchucks (and other animals) all across North America revealed their predictions about the length of this year's winter. Among them were legendary weather forecaster Punxsutawney Phil and rising superstar, Staten Island Chuck.
