Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. A large, stocky, yellowish shark with a broad, blunt snout, narrow, smooth-cusped teeth in both jaws, and equal-sized dorsal fins (Ref. 5578). Yellowish brown above, paler below (Ref. 9997). With two nearly equally large dorsal fins (Ref. 37816).

Found on continental and insular shelves and terraces (Ref. 244). Common on coral reefs (Ref. 5578) and in shallow, sandy lagoons and turbid, mangrove swamps (Ref. 6871). Feeds on smaller sharks, stingrays and on benthic bony fishes (Ref. 5578). Viviparous (Ref. 50449). Dangerous if provoked (Ref. 244). 1 to 11 of 45 cm young are born per litter (Ref. 1602). Meat is utilized fresh and dried salted for human consumption, fins for shark-fin soup base, and liver oil for vitamins (Ref. 244).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Viviparous, placental (Ref. 50449), 1-14 per litter (Ref. 6871). Gestation period 10-11 months (Ref. 5578; Ref.58048). Size at birth about 50 to 70 cm TL (Ref. 9997); 45-80 cm TL (Ref.58048). Distinct pairing with embrace (Ref. 205). Mating and pupping take place during late spring and early summer (Ref. 37816).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.1, mean 28.1 °C (based on 2034 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.1 ±0.6 se; based on diet studies.

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec=1).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).
