Habitat and Ecology [top]

Habitat and Ecology:Labrisomus nuchipinnis is reef-associated and non-migratory. It is a diurnal, bottom-dwelling species which occurs in rocky and rubble shores with algal mats, reefs and seagrass beds, generally at depths of a few centimeters (Cervigon 1994). It is usually seen resting in holes or crevices, and when disturbed quickly move to another crevice. This species is the largest of the labrisomids in the Caribbean region (Smith 1997). It feeds mainly on crustaceans and gastropods (Cervigon 1994), brittle stars, sea urchins, fishes, and polychaete worms (Randall 1996). It is often associated with majid cleaning crabs and Paguristes hermit crabs (Sampaio et al. 2007). 

It is oviparous, spawns in territories, and exhibits paternal care of eggs (Gibran et al. 2004). Mating begins with three stages of courtship: 1) attraction and identification of prospective mate; 2) arousal and appeasement by nudging (the female initiates this move); 3) synchrony occurs when the female starts to rub the rocky wall in the spawning territory, quivering her body against the rock, shaking her anal fin and keeping her dorsal fin erect, the male meanwhile remained perpendicular, biting the sides of the female's body, dorsal fin and upper side of head, and sometimes rubbing her body laterally with his tail. Release of eggs and sperm follows as the male and female bodies quiver. Nest fanning by the male parent comes after this range of display. Driven out by the male, the female moves away from the spawning area while the male continues to patrol the nest, swimming in circular direction and defending the area against other fish. Each cycle lasts for 65.3 seconds, becoming shorter in duration when there are two females involved in the mating event. One cycle is followed by another after the male has returned from patrolling the nest (Gibran et al. 2004).

Larvae are pelagic which eventually settle down at the bottom as juveniles (Carvalho-Filho 1999).
