Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण) : 13; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 12 - 14; गुदा कांटा: 3; ऐनल सौफट रेज़: 5 - 8. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Eye large; 2 strong, sharp, hooked spines on lower margin of suborbital bone; 2nd anal fin spine longer than 3rd in depressed fin (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pinkish red to yellowish red, silvery ventrally; dusky saddles on back, may be vague; green streaks on caudal fin (Ref. 27437).
Mostly found in offshore water on soft bottoms (Ref. 2850). Ovoviviparous (Ref. 6885). Anterolateral glandular grooves with venom gland (Ref. 57406). Commonly caught with trawls but usually discarded because of its small size (Ref. 2850). Rarely taken on baited hook in deep water (Ref. 2850).
Ovoviviparous (Ref. 6885).
