Saint Paul's Rocks country information

Common names: [No common name]
Occurrence: extirpated
Salinity: marine
Abundance: | Ref:
Importance: | Ref:
Aquaculture: | Ref:
Regulations: | Ref:
Uses: no uses
Comments: Inhabits the Palythoa and Caulerpa zone, sub-Caulerpa zone, slope and bay (8-36 meters depth); record based on literature (Ref. 58047). Commonly observed during daytime (Ref. 13067). In 1982, the population was reported as relatively dense but with some evidence of a decline in recent years (Ref. 13067). By 2011, Luiz & Edwards' (Ref. 88827) analyses of the data from recent and historical observations provide strong evidence that the once extremely abundant species is now locally extinct after a sharp decrease in abundance that took place following the commencement of fishing. Also Ref. 13121.

Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 0; колючие лучи анального плавника: 0. Low inter-dorsal ridge present (Ref.9997). Dark grey above, light below, fins plain or with slightly dusky tips (Ref. 9997).

A common but habitat-limited tropical shark found close inshore to well as offshore near or on insular or continental shelves (Ref. 244). Prefers clear water with coral and rocky bottoms (Ref. 244). Although a coastal pelagic species, it is capable of crossing considerable distances of open ocean between islands (at least 50 km) (Ref. 244). Juveniles restricted to shallower water, in 25 m or less (Ref. 244; 37816). Found in superficial aggregations (Ref. 244). Tends to feed near the bottom but may take bait from the surface (Ref. 5485). Feeds mainly on bottom fishes, also squid and octopi (Ref. 244). In the Galapagos Is. it preys on sea lions and marine iguanas (Ref. 28023). Inquisitive and sometimes aggressive, displaying a 'hunch' position ( arched back, raised head and lowered caudal and pectoral fins, while twisting and rolling) near divers that may be followed by biting (Ref. 58085). Viviparous (Ref. 50449). 6 to 16 young of 57 to 80 cm are born per litter (Ref. 1602).

Viviparous, with a yolk sac placenta (Ref. 244). 6 to 16 young born at 60-80 cm (Ref. 26346). Distinct pairing with embrace (Ref. 205).
