Serranus lebretonianus Hombron & Jacquinot, 1853

Data Deficient DD


Body depth contained 3.4 times in standard length (for fish 248 mm standard length). Head length contained 2.3 times in standard length; interorbital area slightly convex; preopercle margin finely serrate, the lower rear edge mostly smooth; posterior nostrils slightly larger than anterior nostils; maxilla reaches vertical at rear edge of orbit; midlateral part of lower jaw with 3 rows of teeth. Gill rakers 7 on upper limb, 17 to 18 on lower limb. Dorsal fin with XI spines and 17 rays, the fourth and fifth spines longest, their length contained 3.5 times in head length and shorter than longest dorsal-fin ray, the interspinous membranes incised; anal fin with III spines and 8 rays; pectoral-fin rays 20; pectoral-fin length contained 1.9 times in head length; pelvic-fin length contained 2.3 times in head length; caudal fin rounded. Lateral-body scales ctenoid; lateral-line scales 73; lateral-scale series about 120.
Colour: Body mottled with brown and covered with small, close-set, dark brown spots; median fins brown, with small blue-edged brown ocelli, the fin margin blackish: paired fins whitish proximally, brown distally.


Probably Indo-Pacific.


The single known specimen is 248 mm standard length.



Interesting facts

E. lebretonianus is known only from the holotype, which was collected during the circum-global voyage of the corvettes “L’Astrolabe” and “La Zélée,” which were attempting to find the South Pole. Hombron and Jacquinot (1853) noted that the provenance of this specimen was unknown; since most of the fishes reported from this voyage were from the lndo-Pacific region, it seems likely that E. lebretonianus was also collected in the Indo-Pacific region.
