The wonders of evolution: Tongue-eating louse (Cymothoa exigua). This parasite enters the fish's mouth (Lutjanus sp.), clings to the tongue's base and extracts all the blood until the tongue atrophies.. Then it replaces the fish's tongue by attaching its own body to the muscles of the tongue stub, and starts to feed on what the host eats; the fish can live normally, and there are even studies around the benefits that he could receive from this parasite. There are no risks to humans.

Terebellid worms belong to a group of segmented worms called polychaetes. Polychaete worms are mostly found in marine habitats and are related to earthworms and leeches. Adult terebellid worms live in various types of permanent tubes in the sediment of the sea floor or on the reef, extending long tentacles to feed. Like most polychaete worms the larva of the terebellid worm is free swimming and planktonic.
