Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 0; Espinhos anais: 0; Raios anais moles: 5; Vértebras: 51 - 53. Diagnosed from all congeners by the presence of three branchiostegal rays, posterior naris absent and the lack of pleural ribs. Differs further from both Typhlobelus ternetzi and T. macromycterus by the absence of eyes, and further distinguished from T. macromycterus by the presence of the nine caudal fin rays and five anal-fin rays and differs further from T. lundbergi by the presence of three laterosensory canal pores (Ref. 56682).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives

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