Free Printable Angler Fish Coloring Page
The anglerfish are fish of the teleost order Lophiiformes. They are bony fish named for its characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the esca.
