Why Do Deep Sea Creatures Look So Scary?

Why Do Deep Sea Creatures Look So Scary? Anna Rothschild of Gross Science explains how different it is at the bottom of the sea: Food can be scarce, there’s tremendous ocean pressure, and it’s dark. These environmental factors have a defining influence on the morphology — the body form, inside and out — of the creatures that live there.

So while they may look like a nightmare, these deep sea animals have adapted perfectly for the place that they live… snaggle teeth, bioluminescent lures, gelatinous flesh, and all.

Related vocab: Aphotic zone, marine snow, photophore, and bioluminescence.
