Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Μαλακές εδρικές ακτίνες: 9; Σπόνδυλοι: 36. Reduced dark pigmentation on the head and body where pigmentation varies from yellowish to light gray, with scattered melanophores limited to the dorsal region of the body. Degree of development of the eyes ranges from their appearing as black dots to being externally invisible. Maxillary barbel extending to the anterior margin of pectoral fin. First pectoral-fin ray, a short filament. Ribs 7. Head length 16-17% SL. Premaxilla rectangular with 3-4 rows; outer row conical (Ref. 46923).

Occurs in small riffles with slow current 15-20 cm deep on average. Exhibits crypto-biotic habits, hiding in the gravel bottom or under limestone blocks. No observed agonistic behavior (Ref. 46923).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00282 - 0.01550), b=2.99 (2.79 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

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