Overview |
Main identification features
- nose stripe black
- point of scythe mark reaches base of dorsal fin spines
- upper back and base of dorsal fin greyish
Southern Scythe butterflyfish, Southern Scythe-marked butterflyfish
Dorsal rays XIII, fin triangular, with front spines longest, 19-20, membranes between anterior dorsal spines deeply incised; anal rays III,14-16; pectoral rays 13-14; lateral-line scales 37-49; second anal spine very elongate, usually longer than pelvic fin length; snout produced, somewhat tubular.
Generally yellow with prominent black scythe-like marking on side, also a black diagonal band from snout to dorsal fin origin.
Very similar to P. falcifer, which is found in the northern part of our region. P falcifer and P carlhubbsi differ as follows: 1. the dark band along the snout is black in P. carlhubbsi and pale grey in P. falcifer; 2. the black scythe mark reaches the base of the dorsal fin spines in P. carlhubbsi but ends well under those spines in P. falcifer; 3. the upper back and base of the dorsal fin are grayish in P. carlhubbsi and yellow in P. falcifer.
Size: grows to 13 cm.
Habitat: rocky reefs.
Depth range 12-270 m.
The Galapagos Islands, Cocos and Malpelo.
Because the differences between P. carlhubbsi and P. falcifer are quite small a genetic study of their relationship could help clear up doubts about the validity of P. carlhubbsi.
