Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Carcharhinidae (Requiem sharks)
Etymology: Negaprion: negatus (L.), to deny; prion (Gr.), saw, referring to lack of saw-like serrations on teeth cusps (See ETYFish); acutidens: acutus (L.), sharp or pointed; dens, from dentis (L.), tooth, probably referring to pyramid-like teeth (“dünnen spitzen Pyramiden”) (See ETYFish).

Length at first maturity / Size / Weight / Age

Maturity: L_m 230.0, range 220 - 240 cm
Max length : 380 cm TL male/unsexed; (Ref. 5213)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).

Trophic level (Ref. 69278): 4.1 ±0.6 se; based on diet studies.

Resilience (Ref. 120179): Very Low, minimum population doubling time more than 14 years (Fec=1).

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

Price category (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 4.33 [0.92, 24.01] mg/100g; Iron = 0.333 [0.079, 0.955] mg/100g; Protein = 21.8 [19.4, 24.0] %; Omega3 = 0.0965 [, ] g/100g; Selenium = 36.1 [10.5, 103.9] μg/100g; VitaminA = 35.2 [11.3, 117.2] μg/100g; Zinc = 0.6 [0.3, 1.2] mg/100g (wet weight);
