Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 1; Rückenflossenweichstrahlen (insgesamt) : 5; Afterflossenweichstrahlen: 10; Wirbelzahl: 32. Diagnosed from other species of the genus Tatia by the following features: males with distinctive modified anal fin, with elongate rays, with no denticulations on ray segments; cranial fontanel wide, with a single opening; infraorbital 1 with pronounced ventral process, almost reaching the antero-ventral border of eye rim; nasal ossified as tubes, with no medial flanges of bone and not sutured to mesethmoid; five branched pectoral-fin rays; and snout deep, depth more than 46.7% HL. Can be further distinguished by having caudal fin lobes with about the same length in both adult females and males; post-Weberian vertebrae 32; and a smaller adult size, less than 5.0 cm SL (Ref. 79512).

Attains sexual maturity at 2.93 cm SL (Ref. 79512).

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=0.01000 (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): 3.2 ±0.4 se; based on size and trophs of closest relatives

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