The Deep Sea Anglerfish (stomach in its mouth). The deep sea anglerfish is one of the most bizarre-looking fish in the sea. It is one of about 200 species of anglerfish found throughout the world's oceans. The angler gets its name from the elongated dorsal spine that supports a light-producing organ known as a photophore. Through a chemical process known as bioluminescence, this photophore can produce a blue-green light similar to that of a firefly on land to lure prey.
