Classification / Names Common names | Synonyms | Catalog of Fishes(genus, species) | ITIS | CoL | WoRMS | Cloffa

Teleostei (teleosts) > Notacanthiformes (Halosaurs and deep-sea spiny eels) > Notacanthidae (Deep-sea spiny eels)

Issue
More probably the larvae of a Notacanthus species after Smith (1989: Ref. 93804), of Notacanthus chemitzii Bloch, 1788 after Moser & Charter (1996: Ref. 35578). Confirmation work/publication still needed. Is uncertain in Notacanthidae in Eschmeyer (CofF ver. June 2013: Ref. 93641).

Estimates based on models

Preferred temperature (Ref. 123201): 2.8 - 8.2, mean 4.3 °C (based on 1093 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100). 🛈
