Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 30 - 36; Épines anales: 0; Rayons mous anaux: 30 - 34. Whitish, pale yellowish brown, pale greyish brown or reddish, often with four brown stripes along sides; second dorsal and anal fins yellow; caudal fin rays yellowish brown, intervening membranes dusky. Pelvic fins rudimentary (Ref. 33839).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Adults are found on the continental shelf and slope, while juveniles school seasonally in inshore waters (Ref. 9563). Juvenile ocean jackets have been caught in seagrass, over bare sand and on rocky reefs (Ref. 6390). Adults however, tend to be absent from seagrass areas (Ref. 6390). Are carnivorous, feeding mainly on salps. Other food items in the diet include gastropod mollusks, crustaceans and fish (Ref. 30465). Sold as fresh trunks (Ref. 6390).
Assumed nonguarder because of high fecundity (RF).
