Check out These Glow-in-the-Dark Animals

Who needs a flashlight when you can glow in the dark?

There are many animals who can glow in the dark. Although most animals with this cool trait live deep in the oceans and seas, there are even a few land animals and insects that glow, too.

You already know at least three glowing creatures: fireflies, glow worms, and bioluminescent bacteria.

And since Smartenings is all about learning new things, by the end of this post, you’ll know eight.

1. The Quantula Striata Snail

These snails are very common in Singapore; you’ll find them in lawns and walkways, especially after rain.

This glowing snail produces dim, yellow-green flashes of light that last 0.5-6 seconds.

They produce these flashes when they are moving. They also flash when feeding, but not when they are still.

Scientists don’t know why they glow, but they think it has something to do with communication.

2. The Anglerfish

You’ll know this fish if you’ve ever watched Finding Nemo.

These fish live deep in the sea where no light reaches.

These fishes use their shiny light to attract prey. They can swallow fish twice their own size

3. The Crystal Jellyfish

Crystal jellyfish live off the west coast of North America.

This jellyfish is almost completely transparent. They give off a bioluminescent glow on the outer borders of their bell when disturbed.

Their glow is blue but then turns green with green fluorescent protein.

4. The Motyxia Millipede

This cyanide-producing millipede warns its predators by producing a green-blue light. They live in Southern Nevada and California.

They have no eyes (so they’re blind), and when you shine a black light on them, they are fluorescent.

Their exoskeleton emits a glowing light caused by a photoprotein. This is a different mechanism that lightning bugs use to emit light (they use luciferase).

5. Glowing Coral

Deep in the Red Sea, there are corals that glow red, green, or orange. While other corals have been found elsewhere that glow green, these corals are much deeper in the ocean and glow with several colors.

The corals produce a pigment that glows, it seems, to make light that helps the algae that live inside them. The algae produce oxygen for the coral.

And we’ll add one that glows under black light:

Bonus:  Emperor Scorpion

The Emperor Scorpion lives in West Africa and grows to an impressive 8 inches long.

They don’t actually emit light, though. Instead, their exoskeleton contains a compound called Beta-carboline which reflects UV light and makes them glow under a black light.

Most species of adult scorpions have the ability to glow green or blue under ultraviolet light, but it’s most pronounced with the Emperor Scorpion.
