Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

A small, slender Galeus with the following combination of characters: claspers extremely long and slender in adult males, distal tips extending to near anal origin or beyond, their outer length 9.2–11.2% TL, 7.2–8.7 times base width; clasper without hooks or spiny denticles; exorhipidion greatly elongated, about 4 times spiracle length when fully developed; anterior inner margin of pelvic fin not fused to clasper; anal fin relatively small, length 9.8–12.0% TL; posterior anal-fin margin 4.7–5.9% TL, 1.4–1.8 in anterior margin of second dorsal fin; prepectoral length relatively short, about 17.8–19.4 %TL; labial furrows moderately long, not confined to mouth corners; enlarged denticle crest of upper caudal fin originating almost over origin of ventral caudal lobe, no abrupt demarcation between denticles of crest and those of caudal peduncle; denticles forming 2–5 central rows of denticles between larger oblique lateral rows near crest origin; no subcaudal crest; anterior margin of pectoral fin black; anterior half of dorsal fins almost entirely dark or dusky; precaudal centra 81–86 (Ref. 76879).
Body shape (shape guide): elongated; Cross section: circular.

Estimates based on models

Preferred temperature (Ref. 123201): 5.6 - 6.8, mean 6.1 °C (based on 6 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00175 - 0.00721), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.2 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (39 of 100).
