Tuna tunnus tynnus lateral Ilustración e icono

Tuna tunnus tynnus lateral. A lateral illustration of a streamlined pelagic fish with dark blue dorsum, silvery flanks, and yellow finlets. The organism is a teleost vertebrate (order Scombriformes) within class Actinopterygii, shown at the whole-organism level with appendicular structures—dorsal, pectoral, pelvic, anal, and lunate CF (caudal fin)—and an operculum covering the gills. In ichthyology and comparative anatomy, these features enable thunniform locomotion for high-speed cruising. The depicted species is Thunnus thynnus, Atlantic bluefin tuna, viewed from the left lateral aspect.
