Description

Wrasses are perhaps the most diverse group of fish in terms of size and form. They are the second most abundant group of fish, exceeded only by gobies. Wrasses have a second set of jaws located in their throat called a pharyngeal jaw apparatus. These jaws are primarily used for the processing of food (just like having a blender in the head). Sex-reversal seems to be universal, with wrasses changing from female to male. These sex changes are normally accompanied by distinct colour changes. Most wrasses are carnivores, feeding on invertebrates or fish; others are planktivores, corallivores, or cleaners that feed on the external parasites of other fish such as the cleaner wrasse.
