Bears are able to live and sometimes thrive from the North Pole to the tropical rainforests around the equator and although they are largely confined to the forests nowadays, in the not too distant past they dominated grassy plains as well. And in overcoming the challenges of each new habitat they migrated into presented, they have evolved to drastically change diets. Bears evolved from small carnivorous animals and yet have become omnivorous, insect eaters, or have a diet occupied entirely of plant foods. So how have bears been able to evolve to eat almost any food in a very small amount of time.
The Hawaiian garden eel is an eel in the family Congridae. It was described by John Ernest Randall and James Robert Chess in 1980. It is a marine, tropical eel which is known from the Hawaiian archipelago, in the eastern central Pacific Ocean. It is non-migratory, and is thought to be restricted to the region.
Hawaii is home to the largest hard-shelled sea turtles in the world.

After over 400 years, these incredible beavers have made a comeback in the UK.
After 50 years, scientists return to Elephant Island off the coast of the Antarctic peninsula to do the seemingly impossible; count thousands of penguins.
245 kilometers off the frigid coast of Antarctica is an island where populations of chinstrap penguins live in the thousands. But these penguins are more than just cute, the health of the Antarctic ecosystem relies on their well-being. the scientists in this next documentary count them. Yeah. By hand, in the freezing cold, walking on steep cliffs. It’s been years since this last happened, and the data collected now will inform them of how one of the most remote places on earth is fairing.
The chinstrap penguin is a species of penguin that inhabits a variety of islands and shores in the Southern Pacific and the Antarctic Oceans. Its name stems from the narrow black band under its head, which makes it appear as if it were wearing a black helmet, making it easy to identify.
