If you're in the Philippines exploring marine life, you'll encounter the Giant Trevally, also known as 'Talakitok' and 'Mamsa,' a top predator in the country's waters. This fish, part of the Caranx genus, can reach up to 170cm in length and thrives in various marine environments. Learning more about its habits and role in the ecosystem can enhance your understanding of the Philippine marine world.

Taxonomy and Phylogeny

In the realm of taxonomy and phylogeny, the giant trevally, classified under the Caranx genus in the Carangidae family, stands as a remarkable species first described by Peter Forsskål in 1775 as Scomber ignobilis. Caranx, a genus to which the giant trevally belongs, was initially placed in the Scomber genus before being correctly reclassified. Often mistaken for the Atlantic crevalle jack due to similarities, the giant trevally holds its place as the largest species within the Caranx genus and the fifth-largest in the Carangidae family.

Belonging to the Carangiformes order, this species is easily identifiable by its strongly forked caudal fin and notably elongated pectoral fins, which exceed the length of its head. The distinct structures of its dorsal and anal fins further contribute to its unique appearance within the Caranx genus. This classification provides a scientific framework for understanding the evolutionary relationships and biological characteristics of the giant trevally.
