> Siluriformes (Catfishes) > Chacidae (Squarehead or angler catfish)
Etymology: Chaca: Because of the sound that this fish makes when out of water (Ref. 45335); serica: Name from the Latin adjective sericus meaning made of silk, or silken, in allusion to the smooth oral margin of the lower lip when compared to Chaca bankanensis, the congener that it superficially resembles most..

Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 1; Rückenflossenweichstrahlen (insgesamt): 4; Wirbelzahl: 33 - 35. Distinguished from Chaca bankanensis by the absence (vs. presence) of a series of rugose ridges on the oral margin of the lower lip, and by having generally longer dorsal and ventral procurrent caudal-ray bases (32.8-37.3% SL vs. 29.4-32.8 and 16.0-19.2% SL vs. 13.6-16.3 respectively), and from both Chaca burmensis and Chaca chaca in having (vs. lacking) nasal barbels, four pectoral-fin rays (vs. five), and lacking (vs. having) a row of fimbriate skin flaps on the body dorsal to (and sometimes ventral to) the lateral line. Further differs from Chaca burmensis by the presence (vs. absence) of papillae around the eyes, a temporal fossa extending (vs. not extending) to the supraoccipital, and fewer serrae on the anterior edge of the pectoral spine (7-8 vs. 11-19) (Ref. 89888)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.7 se; based on size and trophs of closest relatives

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