What type of fish glow in the dark?

Many fish glow in the dark, but they don't actually glow like a light bulb. They bioluminesce, which means they produce their own light through chemical reactions.

Here are some examples of bioluminescent fish:

* Anglerfish: This deep-sea fish has a lure that emits light to attract prey.

* Hatchetfish: These tiny fish have light-producing organs along their bodies, which helps them camouflage and communicate.

* Flashlight fish: This group has light organs under their eyes that they use to attract mates and find food.

* Squid: While not technically fish, some squid species are bioluminescent and use their light to attract prey and communicate.

There are many more bioluminescent fish, and new species are being discovered all the time!
