简单描述 型态特徵 | 形态测量图

A black-spotted longnose skate with an elongated, acutely triangular snout, and a stout tail- just shorter than body and slightly swollen along the mid-section; disc with rounded corners and smooth underside except for small denticles on edges and tip of snout; small thorns on nape and midback to 1st dorsal fin (Ref. 5578). Medium grey to brownish with numerous small dark spots dorsally; grey with conspicuous black pores ventrally (Ref. 5578).
一个有黑色斑点的长鼻 鱼有一个瘦长的, 锐三角形的吻, 与一个矮胖的尾部- 略短于身体与些微肿大沿着中段的; 体盘有圆角与下面平滑的在边缘与吻尖上除了小的细齿; 在后颈与背部中央到第一背鳍上的小的刺.(参考文献 5578) 中等的灰色对褐色的有很多的小深色的斑点背面; 灰色的腹地有明显的黑色孔.(参考文献 5578)

生物学特性     字汇 (例如 epibenthic)

Found on the bottom of the outer shelf and upper slope (Ref. 5578). Probably caught by trawlers (Ref. 5578).Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 57 cm TL, females at ca. 64 cm TL (Ref. 114953)

Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 21.2, mean 14.4 °C (based on 4 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
