- Dorsal and caudal fins with black tips (less evident in adults)
- Interdorsal ridge absent
- Snout moderately long and pointed; internarial space 1.2–1.4 times preoral snouth length
- First dorsal fin relatively high, its height 2.2 times of less in distances between dorsal fins

Cosmopolitan in tropical and warm temperate seas.
Pelagic over continental and coastal shelves, mostly common inshore but sometimes well offshore. Usually found from the surface to 30 meters depth.
Diet consists of bony fish, sharks, rays, cephalopods and crustaceans. Has been observed to occasionally leap out of the water while feeding on small fish. Sometimes forms large aggregations and is often segregated by age and sex. Length at maturity is at 165–180 and 180–190 cm TL for females and males respectively. Age at maturity is around 6–7 years and 5–6 years for females and males respectively in Papua New Guinea. Reproductive mode is viviparous with yolk-sac placenta with a gestation period lasting between 10–12 months. Females give birth every second year to between 1–10 (usually 4–7) pups. Females move inshore to give birth in nursery grounds. Attains a maximum age of at least 12 years in Papua New Guinea.
Commonly caught by shark and tuna longline, and inshore gillnet fisheries. Utilised for its fins (high value in adults), meat, skin and cartilage.
