Redescription and relationships in Weitzman & Malabarba (1999).
Environment: milieu / Zona climática / intervalo de profundidade / distribution range
Ecologia
; Água doce bentopelágico. Tropical
South America: Brazil in lowlands around and to the east and west of the Guanabara Bay, Rio de Janeiro and lowlands around Santos, São Paulo.
Tamanho / Peso / Idade
Maturidade: Lm ? range ? - ? cm
Max length : 2.6 cm SL macho/indeterminado; (Ref. 37055)
Raios dorsais (total) : 10 - 11; Raios anais : 16 - 20; Vértebras: 32 - 34. Lacks infraorbital bone3; the relatively high counts of anal-fin ray (13-16) and ventral procurrent caudal fin ray count (14-17) for S. broccae relative to all other species of Spintherobolus appears autapomorphic for this species.
Inhabits dark-brown swamp waters. Appears to be found in somewhat acid waters in relatively lowland areas, in both swamps and slow moving streams, but only in areas where the streams remain unpolluted.

Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5938 [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).
Nível Trófico (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
