Etymology: Aspidoras: Greek, aspis, -idos = shield + Greek, dora = skin (Ref. 45335); aldebaran: Named after the red giant Aldebaran or Alpha Tauri (α Tauri), the brightest star of the Taurus constellation, deriving from the Arabic al Dabarān, which means 'the follower', This star presents a bright orange glow and it is positioned at the left eye of the mythological bull. A. aldebaran was firstly found among the Aspidoras taurus type series, recognized as a different and new species by its peculiar morphology and color pattern; noun in apposition.

Short description Identification keys | Morphology | Morphometrics

This species is distinguished from its congeners by the following characters: parapophysis of the complex vertebra well developed; inner laminar expansion of infraorbital 1 ranging from well developed to extremely well developed; frontal bone narrow, with width slightly smaller than half of entire length; presence of small black spots on dorsal fin (Ref. 129024).
Body shape (shape guide): elongated; Cross section: oval.

Biology     Glossary (e.g. epibenthic)

The site where some of the paratypes were collected, córrego Gordura, is a medium-sized tributary to the upper rio Araguaia basin with highly transparent and clear water, width ranging from less than one meter to about 15 m, and the depth ranging from about 10 cm to nearly two meters. The species was found in shallow (up to about 20 cm) stretches in the upper portion of the córrego Gordura, with moderate current and substrate composed mainly by sand and gravel. At this site, it was found in syntopy with Aspidoras velites, Characidium sp., and Hypostomus cf. careopinnatus. This species and A. velites were placed in a small biotope aquarium (i.e., one that recreates the natural habitat) to record their color pattern in life. During this event, A. velites displayed aggressive behavior towards an A. aldebaran, chasing and pushing it throughout the aquarium, with the latter specimen not reacting aggressively but tried to evade the assaults by the A. velites. Interestingly, A. aldebaran is generally larger and a clearly more robust than A. velites. In nature, such confrontations seem unlikely considering that the A. aldebaran was generally found associated with the sandy substrate of small shores whereas A. velites was most commonly captured in areas associated with marginal and/or submerged vegetation (Ref. 129024).

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=0.00741 (0.00287 - 0.01912), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
