The French angelfish (Pomacanthus paru) is a species of marine

marine angelfish belonging to the family Pomacanthidae
. It occurs in the Western Atlantic Ocean.

Description

Juvenile

The French angelfish has a laterally compressed body which is almost circular in shape. The head is deep with a short snout ending in a small mouth which contains numerous bristle-like teeth. There is an obvious spine at the corner of the

pectoral fins have a wide orange-yellow band and the dorsal fin has a long yellow filamentous extension growing from its soft-rayed part.[4]

Distribution

The French angelfish is found in the western

Habitat and biology

The French angelfish is found at depths between 3 and 100 m (9.8 and 328.1 ft). It is common on rocky and coral reefs where it is normally encountered in pairs, frequently in the vicinity of sea fans. Its diet comprises

wrasses..[1] When they are trying to draw client fish to the cleaning station the juvenile displays by using a fluttering swimming motion and as it cleans it touches the recipient of its service with its pelvic fins.[2] These fish are active during the daylight hours, but seek shelter in their designated hiding spot where they return every night.[6] They can produce a knocking sound when alarmed.[7]

The pair normally swim a short distance above the reef. There are no obvious courtship displays or clear sexual dimorphism. At dusk, the pair swam upwards in a wide, shallow curve from the substrate, travelling around 7 to 10 m horizontally as they climb to a 2 or 3 m (6 ft 7 in or 9 ft 10 in). As they ascend, both angle their bodies slightly, with their vents very close together, even touching. They hold this posture throughout the zenith of their curve separating as they descend. Neighbouring pairs were observed undertaking similar movements above the reef at roughly the same time. The observers were unable to ascertain if

gametes were released in these displays. Neighbouring pairs were not seen interfering with these displays.[2] This species is a protogynous hermaphrodite, the female can change sex to become a male if no male is present.[7]

Systematics

The French angelfish was first formally described as Chaetodon paru by the

type locality given as Brazil and Jamaica.[8] The species is placed by some authorities in the subgenus Pomacanthus,. The specific name of this species, paru is the Portuguese name for this species.[9]

Utilisation

The French angelfish is common in the

ciguatera poisoning in humans.[2]
