Description

Serranus baldwini has a cylindrical and elongated body, [3] which is laterally compressed to a moderate extent and has a snout which has a length which is shorter than the diameter of the eye. There are 3 well-developed spines on the gill cover, with the middle spine being the largest and straightest. The preopercle has a regularly serrated edge. [4] The dorsal fin contains 10 spines and 11-13 soft rays, [2] while the anal fin has 3 spines and 7 soft rays. The caudal fin is slightly concave. [4] The body is white broken by lines of dark to orange oblong-shaped blotches and spot. There is a noticeable row of dark, oblong blotches along the lower flank. There is a further row of 4 black spots on the caudal peduncle. Fish from deeper water have a red, orange or yellower hue compared to the paler fish from shallower water. [3] This species attains a maximum total length of 12.0 centimetres (4.7 in). [2]

Distribution

Serranus baldwini is found in the western Atlantic Ocean where it ranges from Jacksonville, Florida southwards along the Florida coast and around the Bahamas. Its range extends into the Gulf of Mexico including the Florida Keys and northwards. It is also found along the Mexican coast from Campeche and on the northern coast of the Yucatan Peninsula and from northwestern Cuba throughout the Caribbean, and along the coast of Central America and South America as far south as Sao Paulo in Brazil. [1]

Habitat and biology

Serranus baldwini is a marine reef-associated species, living in rocky and weedy areas at a depth of 1 – 80 m. [2] It shows a strong association with beds of turtle grass (Thalassia testudinum), although juveniles use the empty shells of conches to hide in. It is a territorial species which feeds on shrimps and smaller fishes. [1] It is synchronously hermaphroditic, i.e. fish can be either male or female when spawning but the social structure involves a territorial fish which is the largest of the group functionally male and a harem of hermaphrodites. The male fish is the most successful at producing offspring by mating as a male with the hermaphrodites but the hermaphrodites also mate with each other but do not have the quantity of progeny that the male fish is able to father. [5]

Taxonomy

Serranus baldwini was first formally described as Prionodes baldwini by the American ichthyologists Barton Warren Evermann (1853-1932) and Millard Caleb Marsh (1872-1936) with the type locality given as Culebra, Puerto Rico. [6] The specific name honours the artist on the expedition of December 1898 aboard the United States Fish Commission steamer Fish Hawk to Puerto Rico which collected the type, Albertus Hutchinson Baldwin (1865-1935). [7]

Utilisation

Serranus baldwini is used within the aquarium trade. [8]
