Etymology: Schindleria: Named for ichthyologist Otto Schindler, 1906-1959 (Prof. Dr. Konrad Schindler, pers. comm Dec. 2017).; brevipinguis: From the small size of the species ('brevi') and the deeper, broader ('pinguis' = stout) body.

Short description Morphology | Morphometrics
Dorsal
soft rays
(total): 13;
Anal
soft rays: 10 - 11;
Vertebrae: 35 - 36. Body small, stout, unpigmented. Body depth at pectoral-fin origin 9-12% of standard length and at anal-fin origin 9-14% SL. First dorsal-fin ray at myomere 18-20 and first anal-fin ray below dorsal-fin ray 4. Vertebrae 20 + 15-16 = 35-36, myomeres 19-20 + 14-16 = 34-36. Premaxillae and dentaries lack teeth. Males have a rod-like, flexible urogenital papilla lacking lobes, projections, or accessory papillae, with distal half tapering to a blunt point and usually anteriorly directed.
Recently reported as the smallest vertebrate. Males average 7.7 millimeters long and the gravid female which is 8.4 millimeters weighed 1 milligram. This pedomorphic species has a life span of only 2 months, has dispensed its fishy appendages such as teeth and scales, and has no pigment except in the eyes (Ref. 52508). Specimens were collected in oblique plankton net tows (Ref. 52019).

Estimates based on models
Preferred temperature (Ref. 115969): 26.1 - 27.3, mean 26.3 °C (based on 14 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5625 [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).
Trophic level (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
