The Life of Animals | Wrasse | Wrasses have protractile mouths, usually with separate jaw teeth That jut outwards. Wrasse are sexually dimorphic. Many species are capable of changing sex. Juveniles are a mix of males and females (known as the Initial Phase or IP individuals) but the largest adults Become territory-holding (Terminal Phase or TP) males The wrasses have become a primary study species in fish-feeding due to Biomechanics Their jaw structure.
Hermaphroditism allows for complex systems. Ing Labroids exhibit three different systems: polygynous, lek-like, and promiscuous ing systems. Group spawning and pair spawning occur within ing systems. The type of spawning That Occurs depends on male body size Labroids typically exhibit broadcast spawning, releasing high amounts of planktonic eggs, the which are broadcast by tidal currents; adult labroids have no interaction with Wrasse offspring of a particular subgroup of the family Labridae Labrini do not exhibit broadcast spawning.
Some wrasses are known as the Cleaner wrasse, the best-known of the cleaner fish. They are Symbiotic, or more specifically, mutualistic fish, grooming performing functions for other species of fish, and benefiting themselves by feeding on what They remove. The "client" Will fishes congregate at wrasse cleaning stations and wait for wrasses to swim into Their open mouths and gill cavities to remove gnathiid Parasites.
The Bluestreak cleaner wrasse, Labroides dimidiatus is one of the commonest cleaners found on tropical reefs. Few cleaner wrasses have been observed being Eaten by predators, possibly Because parasite removal is more Important for predator survival than the short-term gain of eating the cleaner. Humans eat wrasse in many places. Wrasse may be employed as cleaner fish to combat sea-lice infestation in salmon farms.
