Western Pacific: Japan and Korea to Viet Nam and the Philippines.

A little-known bottom shark found inshore (Ref. 247); usually in sand or sandy mud bottoms (Ref. 11230); also on rocky and coral reefs (Ref. 43278). Nocturnal in habits (Ref. 247). Feeds on fish and presumably bottom invertebrates (Ref. 247), including lizardfishes, cutlassfish, horse mackerel and other jacks, goatfishes, groupers, tilefishes, sea robins, whiting, parrotfishes, sea bream, croakers, also skates, shark egg cases, cephalopods, and shrimp (Ref. 43278). Ovoviviparous (Ref. 43278, 50449), with up to 20 young in a litter (Ref. 247). Wobbegongs should be regarded as potentially dangerous because of its formidable dentition (Ref. 247, 13577). Used for human consumption (Ref. 247). Kept in aquaria in Japan and the United States (Ref. 43278).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5012 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12 (3.03 - 3.21), based on all LWR estimates for this BS (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.57 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec=20).

Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100) .

Price category (Ref. 80766): Unknown.
