The white trevally (Pseudocaranx dentex) is a silvery fish with blue-green reflections on its back. A yellow stripe runs along its sides, and a black spot is visible near the gill opening.

It inhabits tropical and warm-temperate waters in several oceans. It frequents bays, coastal areas, and continental shelf bottoms, where it often moves in schools.

The white trevally has a streamlined body that is laterally compressed. Its back is blue-green, while its sides and belly are silvery. A yellow stripe runs along its sides and widens toward the rear. A dark spot, usually clearly visible, marks the upper part of the gill cover near the gill opening. Its fins often have yellowish hues.

It typically averages around 16 inches in total length, but the largest individuals can exceed 3.3 feet.

The white trevally inhabits tropical and subtropical waters in several oceans. In the western Atlantic, it occurs from North Carolina, Bermuda, and Florida south to Brazil. In the eastern Atlantic, it is found in the Mediterranean Sea, the Azores, Madeira, the Canary Islands, and Cape Verde, among other locations. It is also found in the Indian and Pacific Oceans, particularly off South Africa, Japan, Hawaii, Australia, and New Zealand.

The white trevally often lives in schools above continental shelf bottoms, near reefs and rocky areas. It may swim near the surface, in open water, or close to the seabed, usually at depths of 33 to 98 feet, although it can also be found much deeper.

Juveniles tend to inhabit shallow coastal waters, particularly bays and estuaries.

The white trevally has a varied diet. It feeds on invertebrates living on or near the seabed, including crustaceans, mollusks, worms, and echinoderms. In open water, it may also consume plankton, particularly small crustaceans such as krill.

The white trevally's breeding season varies by region. In the Azores, spawning takes place mainly in summer, while in Japan it may occur in winter. Eggs and sperm are released into the water, where fertilization takes place. The eggs then drift in the marine environment, where the larvae develop after hatching.

The white trevally has an unusual feeding behavior. It mainly searches for prey on or near the seabed, but it can also feed in open water by filtering plankton as it swims, a method also used by small pelagic fish such as anchovies and sardines.

The white trevally is listed as many other marine species within The IUCN Red List of threatened species. The white trevally appears in the IUCN Red List since 2015 within the category Least Concern !
