Teleostei (teleosts) > Ophidiiformes (Cusk eels) > Carapidae (Pearlfishes) > Pyramodontinae
Etymology: Pyramodon: Greek, pyramis = pyramid + Greek, odous = teeth (Ref. 45335).
Eponymy: The etymology says that the binomial is in honour of “…two mature women who supported and endured this project.” It is not stated, but we presume that the two women, both named Linda, are the authors’ partners. (Ref. 128868), visit book page.

Short description Identification keys | Morphology | Morphometrics

Eel-like, moderate to relatively deep body depth; a large single vomerine fang; pelvic fin rays present; swim bladder large, filling visceral cavity and extending past anus; dorsal and anal fin radials robust and elongate; dorsal fin anteriad or directly over anal fin origin; lacking rockerbone, cardiform teeth, and intrinsic swim bladder constrictions or tunic ridges (Ref. 34024). Margins of dorsal and anal fins edged in black over entire length; head and body generally unpigmented (Ref. 34024).

Uncommon species (Ref. 34024).

Estimates based on models

Preferred temperature (Ref. 123201): 10.9 - 12.9, mean 11.7 °C (based on 12 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [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): 3.8 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).
