जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

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).

Life cycle and mating behavior परिपक्व अवधि | पुनरुत्पत्ति | मछलीऔ का अंडे देना | अंडे | Fecundity | लार्वा

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

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00295 (0.00162 - 0.00538), b=3.08 (2.93 - 3.23), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
लौटाव (Ref. 120179):  निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100) .
