“…Pirate perch, Aphredoderus sayanus (Gilliams), is the only extant species of the family Aphredoderidae (Aphredoderiformes) (Pflieger 1997) and inhabits lowland areas of the Atlantic Slope and the Gulf of Mexico Slope from New York to Texas, in addition to the Great Lakes and Mississippi River Valley (Boltz and Stauffer 1993). The fish is common in swamps and quiet backwaters of low-gradient streams with slow current velocity and abundant aquatic vegetation, woody debris, and undercut banks (Shepard andHuish 1978, Monzyk et al 1997).…”

Analysis of variance results showed significant differences in measurements on 71 specimens of Aphredoderus sayanus comparing standard length (F = 2 1.9 1, P < 0.000 l), maximum depth (F = 8.44, P = 0.006), and standard length to body depth ratio (F = 9.1 1, P = 0.004), indicating that this fish is sexually dimorphic with females being larger and more full-bodied than males. In laboratory observations, a pair of A. sayanus created a nest and successfully spawned, which strengthens the argument that this fish might not be a branchial brooder but instead might be a nest builder with the female releasing adhesive eggs in the proximity of the nest. On three separate daytime occasions, A. sayanus ventured outside its refuge approximately to the point that only its head and anus were exposed, defecated, and then backed into its refuge. The jugular position of the anus might allow adult A. sayanus to partially leave its refuges to defecate to avoid altering water quality and without fully exposing itself to predators. This unique defecation behavior might explain the evolutionary reason for the position of the anus in adult 8.

Pirate Perches, Aphredoderus, are a widespread lowland freshwater fish native to the Eastern half of the United States. Aphredoderus was thought to contain a single species divided into an Eastern and Western subspecies on either side of the Appalachian Mountains with a widespread intergrade zone through much of the Eastern Gulf of Mexico and Southern Atlantic drainages. We use morphology and genetic data from specimens spanning the entire range of the genus to determine species limits within Aphredoderus. We find evidence of five species, four of which exhibit widespread sympatry in the Southeastern United States. We elevate A. sayanus sayanus and A. sayanus gibbosus to species, redescribe A. mesotrema, supplement previous descriptions, and describe two new species, A. retrodorsalis, and A. ornatus.
