Selene (fish)

Selene is a genus of marine fish belonging to the family Carangidae, commonly known as jacks or pompanos. The genus comprises several species, many of which are highly valued for their commercial and recreational importance. They are characterized by their laterally compressed bodies, often with a distinctive silvery coloration. Many species exhibit a prominent dark spot near the base of the caudal fin.

Distribution and Habitat

Selene species are widely distributed throughout tropical and subtropical waters of the Atlantic, Pacific, and Indian Oceans. They are typically found in nearshore environments, including estuaries, bays, and coastal reefs. Some species may also inhabit offshore waters, particularly during certain life stages. Their precise habitat preferences vary depending on the species.

Physical Characteristics

Members of the genus Selene are characterized by their deep, laterally compressed bodies, giving them a somewhat disc-like profile. They generally possess a forked tail fin and a relatively small mouth. Their size varies considerably depending on the species, with some reaching lengths of over a meter, while others remain significantly smaller.

Species

Several species are recognized within the genus Selene, including but not limited to:

''Selene setapinnis'': This species, known as the Atlantic moonfish, is found in the western Atlantic Ocean.
''Selene vomer'': Also known as the lookdown, this species has a wide distribution in the tropical and subtropical waters of the Atlantic, Pacific, and Indian Oceans.
Other species within the genus are less well-documented and may require further taxonomic research.

Ecology and Behavior

Selene fish are generally schooling species. Their diet consists mainly of small fish and crustaceans. They play an important role in the marine ecosystem, both as predators and as prey for larger fish. Specific details on the ecology and behavior of each species are often limited.
