deskripsi pendek Morfologi | Morfometrik

Gymnotocinclus is distinguished from all other hypoptopomatine genera by the following uniquely derived features: extreme reduction of body dermal plates; absence of the lateral connecting bone; absence of bifid hemal spines on the abdominal vertebrae posterior to the first anal-fin proximal radial; and odontode tips on last dermal plates on the caudal peduncle dorsally or anteriorly curved. Gymnotocinclus is also distinguished by a number of non-exclusive traits: maxillary barbel adnateto the lower lip; lateral ethmoid almost completely encapsulating the nasal organ; ventral margin of preopercle straight, not deflected medially; pectoral girdle exposed and supporting odontodes only in a restricted lateral area near base of pectoral fin; and absence of a pectoral-fin slit (Ref. 79020).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00759 (0.00337 - 0.01709), b=3.12 (2.93 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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