It’s hard to imagine a more forbidding place than the icy cold, pitch black, crushing environment of the deep ocean. It’s even harder to imagine anything living there. But researchers are discovering that thousands of fascinating animals—including fishes, corals, crustaceans, jellyfishes, and worms—have adapted to life in this challenging environment.
Many of these animals look quite alien to us. Some have huge eyes—or eyes on long stalks—that capture the little existing light. Others seem to be all mouth. Their gaping jaws—often filled with fanglike teeth—are always open, ready to capture whatever morsels fall from above. Still other deep sea animals have transparent bodies that you can see through, enabling them to blend right in to the waters.
