Background
The crimson snapper was first formally described in 1790 by German physician and zoologist Marcus Elieser Bloch, with the type locality given as Nagasaki. Its specific name, erythropterus, is a compound of the Greek words erythros meaning 'red' and pterus meaning 'fin', referring to its red median fins. Adults are pinkish-red to silver, often with a darker red posterior margin on the caudal fin and a light vertical bar behind the head.
The species has a moderately deep body, a steeply sloped head, large eyes, and a truncate caudal fin. It is mainly nocturnal, foraging at night for fish, crustaceans, cephalopods, and other benthic invertebrates. It is a relatively slow-growing and long-lived species, with a maximum lifespan of 42 years.
