Sustainable construction firm EnviroBuild paid $25,000 for the right to name the amphibian at an auction hosted by the U.S.-based non-profit environmental organization Rainforest Trust.

The dinosaur lived around 85 million years ago.

Scientists fear they may never identify its species now that the dinosaur is in private hands.

The critters are particularly sensitive to other insects—and nosey researchers.

A new study investigated a zone of the ocean where life is so different from the regions above and below that an entirely new category is required to describe it.

It's related to an extremely deadly spider, but it's in its own genus and, thankfully, its venom isn't toxic enough to kill a human.

When the crocs reach their full size, they become trapped inside the caves for the rest of their lives.

The flight speed of these bats has posed difficulties for researchers wishing to study them.

There's no other way to access these unexplored areas than to strap on your scuba tanks and jump in.

It was in the deepest sea trench on earth.
