A glowing snail? Now that’s scary!

A tiny marine snail that looks as if it could be at home dangling from a Christmas tree emits its green glow to scare off would be predators, according to a new study.

The snail, Hinea brasiliana, is a type of clusterwink snail that is typically found bunched up in groups along rocky shorelines. The green glow results from a phenomenon known as bioluminescence — that is, light made by living animals.
