The bleeding wrasse (Polylepion cruentum) is a species of marine ray-finned fish from the family Labridae, the wrasses. It is found in reefs in the eastern central Pacific Ocean.
Description
The bleeding wrasse is relatively slender for a wrasse and its body tapers noticeably towards its tail. It has large eyes and a horizontal mouth which reaches to the eye, in front of the pupil.[2] The largest males have been measured at a total length of 24 centimetres (9.4 in).[3] The adults are red on their heads and upper body with a whitish underside, there are three or four yellow horizontal stripes on the upper flanks and curved yellow stripes on the head. The spiny part of the dorsal fin is black[1] with two pink stripes in the rear portion of that fin and a yellow margin. The anal fin is white with a wide yellow edge, the pelvic fins are also white and the pectoral fins are transparent but have a wide blood-red bar at their base. At the base of the dorsal lobe of the caudal fin there is a large oval-shaped red spot which becomes indistinct in the biggest fish.[2] The juveniles are pink in colour with more yellow stripes than the adults and a large black blotch on dorsal part of the caudal peduncle.[1]
Distribution
The bleeding wrasse is found in the central eastern Pacific Ocean from Mexico to Nicaragua, including the Cocos Islands of Costa Rica.[1] Its range may extend south as far as Colombia and Ecuador.[2]
Habitat and biology
The bleeding wrasse is found at depths of 150–200 metres (490–660 ft) over areas with a sandy substrate near gravel and rocky reefs.[3] It feeds on gastropods, bivalves, crustaceans and worms.[2] It is an oviparous species which pais during spawning[3] and the eggs and larvae are pelagic.[2]
