Anal
soft rays: 5 - 8. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Eye large; 2 strong, sharp, hooked spines on lower margin of suborbital bone; 2nd anal fin spine longer than 3rd in depressed fin (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pinkish red to yellowish red, silvery ventrally; dusky saddles on back, may be vague; green streaks on caudal fin (Ref. 27437).
Mostly found in offshore water on soft bottoms (Ref. 2850). Ovoviviparous (Ref. 6885). Anterolateral glandular grooves with venom gland (Ref. 57406). Commonly caught with trawls but usually discarded because of its small size (Ref. 2850). Rarely taken on baited hook in deep water (Ref. 2850).
Ovoviviparous (Ref. 6885).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00529 - 0.01978), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.7 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (K=0.06; tm=4; tmax=38; Fec=15,000).
Prior r = 0.28, 2 SD range = 0.11 - 0.77, log(r) = -1.27, SD log(r) = 0.5, Based on: 1 K, 6 tgen, 1 tmax, 5 Fec records
Vulnerability (Ref.
59153): High to very high vulnerability (65 of 100) .
