Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Rostral cartilage distally enlarged; anterior nasal prolongations reaching medial margin of nostrils; posterior margin of spiracle with 2 folds, the medial one rudimentary; a line of about 77 prickles between nuchal region and first dorsal fin; 3 or 4 prickles on shoulders, few tubercles on snout and small prickles on anterior margin of orbits; body covered dorsally with about 80 white dots (3 to 5 mm in diameter) over a brown body; underbody white except snout with a black diamond shape blotch, extending backward laterally (Ref. 13259).

Living individuals reported to be in sandy and rocky environments near coral-reefs at 18-24 m depth of the Colombian coast (Ref. 101827). In contrast the type specimen was taken from a depth of 70 m (Ref. 26282). Ovoviviparous (Ref. 50449). Males mature at ca. 71 cm TL (Ref. 114953).

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

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

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00275 (0.00162 - 0.00469), b=3.10 (2.95 - 3.25), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.6 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
