Comprehensive Description

Read full entry
Scomberomorus cavalla, like other scombrid fishes, is elongate, compressed and fusiform. It grows to approximately0.9 - 1.7 m (3 - 5.6 feet) in length and weighs as much as 45 kg (99 pounds). Body color is typically dark blue to black dorsally, with iridescent areas of blue and green. The sides are silver to whitish in color. Young specimens are marked laterally with yellow to yellow-orange spots (Berrien and Finan 1977a), which fade as the animal matures. Two dorsal fins are present, separated by a deep notch between them. A series of 7 - 10 finlets (usually 10) lie posterior to the second dorsal fin and to the anal fin on the ventral surface (Collette and Nauen 1983). The lateral line curves sharply towards the abdomen just below the second dorsal fin. The caudal peduncle is thin and has a fleshy keel. The caudal fin is lunate. The entire body, with the exception of the pectoral fins is scaled. The mouth is large and set obliquely, with the maxillary reaching to just below the orbit of eye. The jaw bears 30 triangular teeth on each side (Godcharles and Murphy 1986).
