Short description आकृति विज्ञान | मौरफोमैटरिक्स

An all-dark longnose skate with its underside uniformly roughened by small denticles; snout acutely pointed and greatly elongated, and tail moderately stout and not conspicuously swollen; pectoral disc angular and broader than in other longnose skates in the area; no nape thorn (Ref. 5578).

जीवविज्ञान     शब्द संग्रह (उदाहरणार्थ epibenthic)

Inhabits the outer shelf and upper slope (Ref. 5578). Rarely caught, probably inhabits hard bottoms that are seldom trawled (Ref. 114953). Feeds on bony fish, crabs and squid (Ref. 5578, Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at 125-135 cm TL, females at 170-190 cm TL. Smallest known specimen at 27 cm TL (Ref. 114953) Probably caught by hake trawlers (Ref. 5578).

Estimates based on models

Preferred temperature (Ref. 115969): 6.4 - 12.5, mean 10.4 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00147 - 0.00681), b=3.22 (3.04 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.3   ±0.69 se; based on food items.
लौटाव (Ref. 120179):  निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Very high vulnerability (85 of 100) .
