Spinner dolphins (scientifically “Stenella longirostris”) are known for their high-speed acrobatics and joyful energy in the ocean. They get their name based on their common behaviour, that is, getting out of the water and spinning!
They’re one of the most loved marine mammals in tropical waters and a common sight in Hawaiian waters. This guide dives deep into their behavior, where they live, what they eat, and why they spin through the air.

What Are Spinner Dolphins?
Spinner dolphins are part of the toothed whale family. They’re famous for their ability to leap into the air and spin multiple times before diving back into the ocean.
There are different types of these dolphins, including the eastern spinner dolphin and the long-snouted spinner dolphin. The hawaiian spinner dolphin is the most commonly seen subspecies in the warm waters around the islands, showing off their acrobatic skills!
Where Do Spinner Dolphins Live?
The long nose dolphin lives in warm, tropical oceans around the world. In Hawaii, they’re most active along the coastlines, including Oahu. During the day, they rest in calm, shallow bays. At night, they travel into deeper waters to hunt.
Spinner Dolphin Habitat and Adaptations
The spinner dolphin habitat includes warm, shallow coastal waters, coral reefs, and lagoons. They prefer clean and quiet environments where they can rest during the day without disturbance.
Several adaptations of these dolphins, including camouflage and specialized diving ability, help them survive and thrive in the wild. Their streamlined bodies reduce drag and allow them to swim fast.
Their long, narrow beaks help them catch small fish and squid. These long nose dolphins also use echolocation to find food and communicate with other dolphins.
What Do Spinner Dolphins Eat?
If you’re wondering, “what do spinner dolphins eat?,” know that these dolphins are carnivores. Their diet mostly includes small fish and other small creatures like shrimp and squid. At night, they dive deep and hunt in groups to surround schools of fish. They use speed, sound, and teamwork to catch their prey efficiently.

Spinner Dolphin Behavior
These dolphins are highly social animals. They travel in pods of 50 to 100 dolphins. In larger areas, pods can merge into superpods with hundreds of dolphins. They communicate through clicks, whistles, and body language. Their teamwork in hunting is an important part of spinner dolphin behavior.
Scientists believe these dolphins spin to show excitement, to get rid of parasites, or to communicate with fellow dolphins.
They’re most active at dawn and dusk. During the day, they rest in nearshore waters where it’s quiet. At night, they swim deeper to hunt.
Spinner Dolphin Facts
Here are some quick spinner dolphin facts:
- They can jump up to 10 feet high when they leap out of water.
- They can spin up to seven times in a single leap out of the water surface.
- Their top speed reaches around 25 miles per hour.
- Spinner dolphin lifespan in the wild is about 20 to 25 years.
- They have sharp, pointed teeth, ideal for grabbing slippery fish. Their teeth count (180 to 260) is also higher than any other cetaceans.
- They can dive up to 300 meters deep while hunting.
How Much Do Spinner Dolphins Weigh?
Adult spinner dolphins weigh up to 170 pounds. Their length can reach up to 2.4 meters. The males are often slightly larger than the females.
Another of the spinner dolphin facts is that their light body weight and strong muscles allow them to spin, leap, and travel long distances without using too much energy.
Spinner Dolphin Reproduction
These dolphins give birth to one calf every 3 years. Calves are born after a pregnancy of about 11 months. At birth, a baby dolphin is about 0.8 meter long and can weigh up to 20 pounds.
Mothers nurse their young for up to two years. During this time, calves stay close to their mothers and learn how to hunt and interact with the pod.
Protection of Spinner Dolphins
Like many marine animals, spinner dolphins face threats from human activity, including pollution and illegal fishing practices. In Hawaii, there are strict rules to protect these dolphins.
