Australian Faunal Directory FishBase 1 thumbnail  •  slide show español Overview Main identification features large spiny scales entire lateral line curved part ll: height spines greater than 60 percent eye Inca Scad Large fatty eyelid covers rear half of eye; dorsal fin VIII + I, 30-36, without finlet behind; anal fin with II isolated spines followed by I, 27-31; lateral line with extension along top of back under dorsal fins; pectoral fin long, reaching past origin of anal fin; scales along entire length of lateral line forming large spiny scutes, those on curved part of the lateral line relatively large (61-85% of eye diameter); body long and slender, slightly compressed. Back and top of head metallic blue to dark grey; lower body whitish to pale grey; a black spot at the upper edge of the gill cover. Size: reaches 70 cm, common to 45 cm. Habitat: an inshore pelagic species. Depth: 10-300 m. Southern Ecuador to Peru, Galapagos and Malpelo. Also occurs in New Zealand. T. symmetricus, which occurs from California to the Gulf of California, is the sister species of T. murphyi. T. symmetricus has smaller scutes (height = 25-44% of eye diameter) on the curved part of the lateral line than does T. murphyi. A recent study by Stepien + Rosenblatt (1996) indicates that are ongoing genetic connections between these two populations. Attributes Abundance: Common. Cites: Not listed.
