6. Northern Stargazer (Astroscopus Guttatus)
This fish must have gotten its name from its face. Due to their eyes, nostrils and most of its mouth are on top of its body. It would burrow itself into the sandy sea floor with only its eyes somewhat visible for it to see its oblivious prey. Other than the element of surprise, it can also produce an electric shock which either be used for immobilizing its prey or as a defense mechanism.
5. Tongue-eating Louse (Cymothoa Exigua)
Crustaceans. Parasitic crustaceans. They are very small and they would enter the fish through their gills and then crawls from the inside of the fish attaching itself to the fish’s tongue. Well the female would attach itself to the tongue while the male would attach itself on the gill arches. The parasite severs the blood vessels of the fish’s tongue causing it to fall off and then replaces the tongue with itself. Apparently the parasite can change its sex to either male or female for the sake of reproduction.
