Etymology: Trematomus: Greek, trematos = hole + Greek, tomo = section, cut (Ref. 45335);  amphitreta: Name from Greek, genus translates as 'from the cold' and specific epithet as 'an orifice with two openings', describing the interorbital-pit morphology that distinguishes it from C. peninsulae..

Short description Identification keys | Morphology | Morphometrics

This species is distinguished by having its pelvic fins reaching only about halfway from the pelvic-fin base to anal origin, and the second dorsal-fin insertion notably advanced with respect to the anal-fin origin; cephalic lateral-line pores large, the fourth supraorbital canal pores open into a median, well-defined, depressed interorbital pit, divided medially by a slightly raised ridge; width of depressed interorbital region greater than the length, does not extend anteriorly beyond the third supraorbital canal pore, and with a few uniserial cycloid scales immediately anterior to it; the lining of the mouth, gill cavities, and peritoneum black (Ref. 58577).

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=0.00537 (0.00280 - 0.01029), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
