Actinopterígios (peces con aletas radiadas) > Tetraodontiformes (Puffers and filefishes) > Tetraodontidae (Puffers) > Tetraodontinae
Etymology: Pelagocephalus: Name 'Pelagios' meaning of the sea, in allusion to the envisioned offshore, openwater habitat and 'cephalus' or head, in allusion both to the sleek head and to the similarity of the name with that of Lagocephalus (rabbit head; appropriate for most species, but not for the two which are pelagic), one of the several genera closely related to it.; coheni: Named for Dr. Daniel M. Cohen, former Director of the National Systematics Laboratory of the National Marine Fisheries Service, Washington, D.C.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02692 (0.01222 - 0.05929), b=2.88 (2.70 - 3.06), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.3 ±0.3 se; Based on size and trophs of closest relatives

Resiliencia (Ref. 69278): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
