Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

This species is distinguished from its congeners in having the following set of characters: two rows of thorns (strongly hooked and gradually becoming somewhat embedded toward first dorsal fin origin) on mid-dorsum of tail; no thorns at the anterior part of scapular region; thorns on the orbital, nape and scapular regions not encircled by light yellow or white pigment; dorsal surface covered with minute dermal denticles of uniform size and shape, no obvious larger dermal denticles (smooth to touch) (Ref. 86259).

Found inshore (Ref. 9903), above 60 m on rock or rocky sand bottoms (Ref. 11230). Ovoviviparous (Ref. 50449). Biology little known (Ref. 9903).

Life cycle and mating behavior Maturities | पुनरुत्पत्ति | Spawnings | Egg(s) | Fecundities | लार्वा

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).
