The cleaner wrasse change
Main article: Cleaner fish
Cleaner wrasses are the best-known of the cleaner fish.
Feeding methods change
They are carnivores, feeding on a wide range of small invertebrates. Many smaller wrasses follow the feeding trails of larger fish, eating invertebrates left by big fish.[3]
Wrasses can put their jaws forwards, usually with separate jaw teeth that jut outwards.[4]
Many species can be recognized by their thick lips. The inside of these lips is curiously folded, which gave rise the German name of Lippfische. The dorsal fin has 8–21 spines and 6–21 soft rays, usually running most of the length of the back.
Wrasse are sexually dimorphic. Many species are capable of changing sex. Juveniles are a mix of males and females (known as Initial Phase or IP individuals) but the largest adults become territory-holding (Terminal Phase or TP) males.[4]
