deskripsi pendek Morfologi | Morfometrik

Nostrils are longer, crown is flat transversely or even slightly convex, tubercles in median row are larger, thorn like, numerous. Origin of first dorsal is posterior to the tips of pelvic fins, equal to the base of first dorsal. Upper surface uniform olive gray or chocolate brown, without pale or dark markings. Snout with an oval sooty patch (Ref. 6902).

Found from the coast line to the continental edge. Females mature at ca. 90 cm TL (Ref. 114953). Feeds on crustaceans, cephalopods, polychaetes and small fishes. Ovoviviparous (Ref. 50449). Produces litters of 4-12 pups (Ref. 114953).

Life cycle and mating behavior Kematangan | Reproduksi, perkembang biakan | Pemijahan | telur-telur | Fecundity | Larva

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 11.6 - 22.7, mean 15.6 °C (based on 248 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (0.00135 - 0.00588), b=3.12 (2.95 - 3.29), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.49 se; based on food items.

Daya lenting (Ref. 120179): sangat rendah, Waktu penggandaan populasi minimum lebih dari 14 tahun (Fec=4-12).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (83 of 100).
