Teleostei (teleosts) > 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 based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02570 (0.01193 - 0.05536), b=2.88 (2.71 - 3.05), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.2 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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