Aphredoderidae (Pirate perches)
Etymology: Aphredoderus: Greek, aphod = excrement + Greek, dere = throat, in reference to the unusual postion of the anus (Ref. 45335); sayanus: From the Greek aphod=excrement, and dere=throat, from the position of the anus; sayanus, named after an entomologist, Thomas Say (Ref. 79012).

पारिस्थितिकी
; स्वच्छ जल, अलवण जल ड़िमरसल. Temperate; 5°C - 26°C (Ref. 12468); 46°N - 28°N
North America: Eastern and central United States. Previously, two subspecies were recognized by Boltz & Stauffer 1993 (Ref. 34807): Aphredoderus sayanus sayanus in Atlantic Coast drainages from New York to Georgia; and A. sayanus gibbosus in the Mississippi River, Great Lakes, and western Gulf Coast drainages, with intergrades in Gulf Coast and Atlantic Coast drainages between Mississippi and Georgia.

Adults usually occur over mud in swamps, vegetated sloughs, ponds, lakes, backwaters, and quiet pools of creeks and small to large rivers (Ref 5723, 10294). Nocturnal feeders. Feed on aquatic insects, small crustaceans, and occasional small fish including their own young (Ref. 10294). Eggs in nests are guarded by both parents (Ref. 205).

50 = 1.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00170 - 0.01173), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.39 se; based on food items.
Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
