Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Elasmobranchii (sharks and rays) > Orectolobiformes (Carpet sharks) > Orectolobidae (Carpet or nurse sharks)
Etymology: Orectolobus: Greek, orektos = stretch out + Greek, lobos = lobe (Ref. 45335).

Environment / Climate / Range Ecology

Marine; reef-associated; depth range 0 - 100 m (Ref. 54689).   Tropical; 1°N - 40°S, 114°E - 154°E

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: Indonesia, Papua New Guinea, south to Australia (including southern Australia and Western Australia). Apparently questionable in Japan and the Philippines (other sources).

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 94 - ? cm
Max length : 290 cm TL male/unsexed; (Ref. 6871)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0. Back with light areas between dark saddles marked with dark, light-centered blotches and spots, not reticulated lines (Ref. 13577). Caudal fin with its upper lobe hardly elevated above the body axis, with a strong terminal lobe and subterminal notch but no ventral lobe (Ref. 13577).

Biology     Glossary (e.g. epibenthic)

A common bottom shark of inshore continental waters, on algal-covered rocky areas and coral reefs (Ref. 247). Nocturnal, resting on the bottom during the day and prowling on its reef habitat at night (Ref. 247). Presumably feeding on bottom invertebrates and fishes but diet unrecorded (Ref. 13577). Ovoviviparous (Ref. 50449). Attacks waders and fishers in tide pools (Ref. 247). Interest to fisheries limited; its skin very tough and attractively patterned and utilized for leather (Ref. 13577).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Ovoviviparous, embryos feed solely on yolk (Ref. 50449).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5012   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.60 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Prior r = 0.16, 2 SD range = 0.03 - 0.78, log(r) = -1.83, SD log(r) = 0.79, Based on: 1 K, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153):  High vulnerability (60 of 100) .
