A female spinner dolphin reaches maturity at the age of 4 to 7 years while the male dolphins mature at around 7 to 10 years. The mother suckles her calf for about 1 to 2 years.

Spinner dolphins inhabit tropical and subtropical coastal and off-shore waters. In Hawaii, they are clustered along coastal bays but in other regions, they inhabit deep-water of the oceans. During the day, they tend to rest at shallow coastal bays but begin foraging for fish in the sunset.

The primary diet of these dolphins consists of deep-water squids, fish and family of prawns called sergestid shrimps. They can dive down to a depth of 650 to 984 feet in search of food.

The predators of the spinner dolphins are the short-finned pilot whale, the orca, the pygmy and false killer whales as well as sharks.
