Bluehead Wrasse Juveniles

Thalassoma bifasciatum

Description:

Young/small females and males have yellow upper bodies and white lower bodies, often with green or black lateral stripes and occasionally dark vertical bars. This coloration is known as the initial phase. They can rapidly alter the presence or intensity of their yellow color, stripes, and bars, and these color changes appear to correspond to behavioral changes. Though bluehead wrasses are common cleaner fish in the coral reefs they inhabit, they avoid cleaning piscivores such as the spotted moray, the graysby, and the red hind. Such species will view them as prey, but will not view gobies, another kind of cleaner fish, as prey. Other predators include the greater soapfish, roughtail stingray, and the trumpetfish.

Habitat:

Coral reef in Weber's Joy/Witches Hut in Bonaire.
