Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 0; Raios dorsais moles (total): 0; Espinhos anais 0; Raios anais moles: 0. A small, slender shark with an extremely short, broad snout, oval eyes, and conspicuous white tips on the 1st dorsal (sometimes 2nd) and upper caudal fins; 2nd dorsal almost as large as 1st; no interdorsal ridge (Ref. 5578). Spiracles usually present, teeth 47-50/ 44-46, in at least 2 functional rows. Grey above, lighter below and sometimes with dark spots on sides (Ref. 5578). First dorsal-fin lobe and dorsal caudal-fin lobe with conspicuous white tips, second dorsal-fin lobe and ventral caudal-fin lobe often white-tipped (Ref. 9997).

Biologia     Glossário (ex. epibenthic)

Sluggish inhabitant of lagoons and seaward reefs where it is often found resting in caves or under coral ledges during the day (Ref. 6871, 58302), or usually on a sand patch, or in a channel (Ref. 37816). More active at night or during slack tide in areas of strong currents (Ref. 37816). Feeds on benthic animals such as fishes, octopi, spiny lobsters and crabs (Ref. 244). Viviparous (Ref. 50449). Travels distances from about 0.3 to 3 km in periods up to about 1 year (Ref. 244). Rarely reported to attack humans, but is potentially dangerous especially when fish had been speared (Ref. 244). Probably fished wherever it occurs (Ref. 244). Caught by inshore longline and gillnet fisheries, and probably adversely affected by dynamite fishing (Ref.58048). Meat and liver utilized fresh for human consumption (Ref. 244). The liver of this shark has been reported as toxic (Ref. 583). One to five 60 cm young per litter (Ref. 1602).

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Viviparous, placental (Ref. 50449), with 1 to 5 young per litter (Ref. 244); usually 2 or 3 pups after a gestation period of > 5 months (Ref.58048). Size at birth 52-60 cm TL (Ref. 9997). Distinct pairing with embrace (Ref. 205). During courtship and prior to copulation, the male bites the female on her right pectoral fin and uses his medially flexed right clasper in copulation (Ref. 49562, 51119). During copulation which lasts from 15 seconds to 4 minutes (Ref. 49562, 51119), both heads of the male and female are slammed in the substrate and their bodies undulate to keep their tails elevated (Ref. 51155). This mating behavior was observed in individuals bred in captivity.
