Description
The lane snapper has an oblong, compressed body.
It has a sharply pointed snout,
With a pair of front and a pair of rear nostrils which are simple holes, it has a relatively large mouth with a moderately protrusible upper jaw which has most of its length below the cheek bone when the mouth is shut., Each jaw has one or more rows of sharp, conical teeth with a few of these being enlarged to form canines. The vomerine teeth are arranged in an anchor shaped patch of teeth with a short rearwards extension along the middle of the palate and there is a pair of tooth patches ar either side of the palate. The preopercle is serrated,

Reproduction
Lane snapper form spawning aggregations, off Cuba these aggregations are found from March until September, peaking in activity in July and August. Off Puerto Rico spawning reaches its zenith in May. They are broadcast spawners, the fertilised eggs drift on the currents and hatch after 23 hours. The larvae are little known but settle at a length of about .[

Predators
The lane snapper is preyed upon by larger fishes and sharks.[

Fisheries and conservation
The lane snapper is prized for its tasty, white meat, which is sold in supermarkets throughout Mexico. Lane snapper are more typically caught in shallower waters than many other snappers, most commonly yellowtail snapper and gray snapper. Larger specimens can be found in somewhat deeper waters, but are typically less plentiful.[ The consumption of its flesh has been known to result in cases of ciguatera poisoning.][
Lane snapper are caught with beach seines, boat seines, traps, handlines, and bottom trawls. Shrimp fisheries take for a large portion of the total catch of this snapper, due to the juveniles preference for soft bottom s with high populations of shrimps.][
The lane snapper stocks have shown steep declines as a result of overfishing in much of its range. For this reason the IUCN have assessed this species as ]Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify f ...
