Seven Tips On Animals That Glow In The Dark

ANGLER FISH
The angler fish looks like the kind of terrifying deep-sea predators that will induce nightmares. But this gruesome-looking fish has a fascinating bioluminescent organ.

FIREFLIES
The firefly (also known as the lightning bug) is a family of beetles, encompassing around 2,000 known land species. During the summer, they light up the night sky with their amazing bioluminescent ability. The main purpose of the glow is to attract mates.

JELLYFISH
The humble jellyfish is perhaps the most bioluminescent animal on the planet. It’s estimated that about half of the 2,000 or so known species exhibit some kind of glowing ability.

KRILL
The krill are tiny marine crustaceans, most of them measuring no more than an inch or two long. They are very common prey for larger marine organisms like whales, which sweep them up in the thousands. These inconspicuous organisms also have the amazing ability to produce light from their bodies.

TASMANIAN DEVIL
In December 2020, a zoo technician first found that Tasmanian Devils can produce a visible glow under the gaze of ultraviolet light. Special proteins in the skin and fur appear to absorb energy from the sunlight and then emit the energy at dusk in a different wavelength beyond what the human eye can process.

FIREFLY SQUID
While only a few species of squids are able to light up, the firefly squid is a spectacular exception.

TOMOPTERIS
Tomopteris is a genus of plankton (small floating marine organisms found all over the world’s oceans). While many types of plankton produce light, this is the only one that produces a rare yellow bioluminescent glow.
