Morphology | Morphometrics
Distinguished by the following characteristics: very small eyes; light pink body color with darker red areas composed of blood capillaries close to surface; elongate body; first dorsal with VII spines; upper and lower jaws with enlarged, widely spaced teeth that overlap the lips of both jaws; greatly reduced head pores, occasionally absent (Ref. 92840).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
