|Taxonomic Notes:||Labrisomus nuchipinnis is likely a species complex and there is only one species in the Gulf of Mexico (J. Williams pers. comm. 2014). The holotype of L. nuchipinnis is from Brazil, so the name will change.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Reviewer(s):||Polidoro, B., Carpenter, K.E. & Strongin, K.|
Global Assessment: Labrisomus nuchipinnis is widely distributed with a presumed large overall population. It has no known major threats. Therefore, it is listed as Least Concern.
Gulf of Mexico Regional Assessment: Labrisomus nuchipinnis is distributed throughout the Gulf of Mexico, except for the northern coast. It has no known major threats. Therefore, it is listed as Least Concern.
|Range Description:||Labrisomus nuchipinnis is distributed in the western Atlantic from Jacksonville, Florida, Bermuda, the Bahamas, throughout the Gulf of Mexico except for the northern part from Galveston, Texas to Cedar Keys, Florida, and throughout the Caribbean. Reports from the eastern Atlantic require taxonomic review.|

|Population:||Labrisomus nuchipinnis is occasional, but can be locally abundant (Humann and DeLoach 2002). It is not common off Mexico in the Gulf of Mexico (M. Vega-Cendejas pers. comm. 2013).|
|Current Population Trend:||Unknown|
|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).
