पारिस्थितिकी
समुद्री ड़िमरसल; गहराई सीमा 0 - 360 m (Ref. 9563), usually 0 - 200 m (Ref. 6390). Subtropical; 22°S - 39°S
Eastern Indian Ocean: southern Australia, from Western Australia to New South Wales. The species is considered to be endemic to Australia, although a single specimen has been reported from New Zealand (Ref. 30464).
Length at first maturity / आकार / वज़न / Age
Maturity: Lm ?, range 37 - ? cm
Max length : 100.0 cm TL पुल्लिंग / अलिंग; (Ref. 9563); अधिकतम प्रकाशित वज़न: 3.5 kg (Ref. 27296); अधिकतम सूचित उम्र: 9 वर्षो (Ref. 30466)
पृष्ठीय रीढ़ (सम्पूर्ण): 2; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 30-36; गुदा कांटा 0; ऐनल सौफट रेज़: 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).
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).
