Found in coastal and oceanic waters. Generally found in schools, leaping out of the water. Feeds on planktonic crustaceans and possibly small fishes and cephalopods.

Ovoviviparous, 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. A single, relatively large pup is produced per litter.
 

This species is not protected or subject to fishery regulations despite being an appendix I species under the Convention on Migratory species to which Seychelles is party. 
It is caught in gill nets. It is a periodic and occasionally numerous component of the catch.
