Can You Name These Deepwater Creatures?

Can you name all 35 of these creatures from the deep?

Introduction

Travel far enough down beneath the surface of the ocean and you'll reach a place devoid of light but full of fascinating creatures like the anglerfish or goblin shark. These deepwater creatures have evolved amazing adaptations in order to survive in this extreme environment. Many have large eyes or are bioluminescent (i.e., they can make themselves glow) in order to cope with the lack of light. Most have flexible skeletons and gelatin-like bodies so they can survive the immense pressure of the ocean far beneath the surface.

Because of these intense environmental conditions, many believed life would be impossible or extremely scarce in the deep sea. This is not the case, however; there is an abundance of life in the deep sea. Many animals get sustenance from biomaterials that have sunk to these depths, from preying on other creatures, or from deep-sea hydrothermal vents (animals can thrive on the chemical reactions that take place here).

Many of us have seen pictures on our social media feeds of Mr. Blobby the Blobfish, unfortunately often dubbed the ugliest animal in the world (blobfish actually look quite cute in water). Finding Nemo introduced many of us to the anglerfish. Or, if you have access to Discovery Channel or Animal Planet, you've probably seen a documentary or two about the almost alien world that exists beneath the surface of the ocean.

How many deep-sea creatures can you name? Can you tell apart an anglerfish from a blobfish? Could you point out a picture of a goblin shark? There's only one way to find out. Take this quiz to see if you're a deep-sea creatures expert! (If you want to learn more about these amazing creatures before taking this quiz, we recommend studying up at Out of the Box Science, which has some great articles about these animals).
