Short description ສະລີລະວິທະຍາ | ການວັດແທກຮູບຮ່າງລັກສະນະພາຍນອກຂອງດິນ,ສັດ,ປາ…

ສັດທີ່ມີກະດູກສັນຫຼັງ: 155. This slender-bodied shark is readily distinguished from its larger congener (H. griseus) by having a narrower head, relatively larger eyes, 5 large lower comb-shaped anterolateral teeth, a long slender dorsal-caudal space, with distance from the dorsal origin to the upper caudal origin being at least twice the length of the dorsal fin base; with the upper and lower caudal postventral margins forming a strong arch. In life, Color of dorsum a uniform pale brown without a light line extending along the lateral body trunk, the trailing fin edges are white in some specimens and the ventral surface is lighter (Ref. 94780).

ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Found on continental and insular shelves and upper slopes, from 90 to 600 m depth, usually on or near bottom, may move to the surface at night (Ref. 247, 5578). Probably feeds on bony fish and crustaceans (Ref. 13573). Ovoviviparous (Ref. 205), with 13 young in a litter (Ref. 247). Size at birth measures to about 40-43 cm TL (Ref. 94780). Not dangerous to people as far as is known (Ref. 247). Utilized for its fins, meat and liver oil but of little value due to its relatively small size (Ref.58048).
