Answer:
Firefly Squid
While most squid don’t glow there are a few species of them that do. The most known glowing squid is called the “firefly squid“. The firefly squid gets its name from its flashing lights which resemble the glow of fireflies.
It is able to glow like this due to a light producing organ called “photophores“ which can be found all over the squid’s body. The squid has full control of these lights, meaning that it can alternate the pattern of its light in any desired way.
Catshark

Outside the coasts of the US there are species of catshark with the ability to glow. These sharks mostly use their fluorescent abilities to communicate with eachother and to camouflage in reefs much like the sea turtle.
While their general glow is very apparent it wasn’t always apparent that they use it for communicative purposes. This was only discovered when scientists shined a specific light on them which revealed this property of theirs.
The catshark grow to be around 3 feet (90 cm) long and spend a lot of their time on the bottom of the ocean floor hiding in crevices.
Jellyfish

Jellyfish as a species are some of the most luminescent animals on this planet. It is estimated that around 50% of them are bioluminescent.
Bioluminescence is different from biofluorescence in the nature the light emitted is created. Bioluminescence light is created directly from a chemical reaction occurring within the animal whereas biofluorescence requires the absorption of light to then re-emit it.

These bioluminescent jellyfish can be found all around the world’s oceans due to their widespread within them. While they are spread across the entire world they mostly reside in the deeper parts of the water due to it being the most effective at greater depths.
The main use of their bioluminescent abilities is for the defense against the various predators they might run into.
Some jellyfish will use bright flashes to startle and confuse predators whereas others are able to detach their own tentacles as a means to confuse them, effectively acting as a decoy. The different strategies the jellyfish uses regarding their bioluminescence is rather diverse and creative.
Explanation:
Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs.
