Short description সনাক্তকারী নির্দেশক | বহিঃ অঙ্গ সংস্থান | মরফোমেট্রিক্স

Spines are larger toward front and disappear with age on rear parts of tail. Few scapular spines. Group of spines in front of and around each eye. Adults have 1 middorsal row of many small spines, 1 row of small spines on each side, middorsal row of spines extend forward on disk to area behind eyes. Young have 2 pale crossbars on tail, each outlined by a dark blotch or band. Snout pointed (Ref. 7251). Upper surface pale brown with numerous obscure darker spots, irregular pale markings. Lower surface plain white with few small dusky spots (Ref. 6902).

জীববিজ্ঞান     শব্দকোষ (উদাহরণ স্বরূপ epibenthic)

Inhabits soft mud and clay bottoms of the deeper troughs and basins, sands and shells, gravel and pebbles of the offshore fishing banks (Ref. 6902). Benthic (Ref. 5951). Salinity ranges from 32.6 to 35.4 (Ref. 6902). This species is confined to deep water. No occurrence has been found in less than 8 m of water. Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 5.0-5.9 cm long and 3.8-4.5 cm wide (Ref. 41249, 41306, 41301). Caught too sparingly to have any commercial importance (Ref. 27314).

Life cycle and mating behavior Maturities | প্রজনন | Spawnings | Egg(s) | Fecundities | শুককীট

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
