Schindleriidae (Infantfishes)
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..

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 13; Raios anais : 10 - 11; Vértebras: 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).
