Put it back.

The never-before-seen animal is a sea spider — a distant relative of horseshoe crabs and arachnids that live on the ocean floor, eat through a straw-like proboscis instead of a mouth and breathe through their legs.

Neat.

Also, I wonder if it's tasty.

In a few years' time it's going to be one of the more appetising of the ocean's remaining foodstuffs.
