Striped Dolphin Q&A
What kind of dolphin is the striped dolphin?
The striped dolphin is a species of dolphin belonging to the genus Stenella.
As their name suggests, they are characterized by the beautiful bluish-white stripes running along their sides. In English, they are called 'striped dolphins.' They are very active dolphins, often seen leaping, spinning, and riding waves. They are known for their high intelligence and social behavior, living in large groups called pods, sometimes numbering in the hundreds or even thousands!
What do striped dolphins eat?
Striped dolphins are carnivores and primarily feed on fish, squid, and krill.
They use their sharp teeth to catch their prey. They hunt in groups, herding and encircling their prey. They also use echolocation to find their prey, emitting sound waves to understand their surroundings and pinpoint the location of their prey.
[Quiz!] How do striped dolphins jump?
Striped dolphins are known for their high leaps out of the water.
They can jump up to 23 feet (7 meters) high! They also sometimes spin and somersault in the air as they jump. It's truly a breathtaking spectacle! While the reasons behind their high jumps are not entirely clear, there are a few theories:
・To shed parasites: Jumping may help them dislodge parasites from their bodies.
・To communicate with other dolphins: Jumping could be a signal or a form of communication with other dolphins.
・For fun: They may simply enjoy jumping!
Whatever the reason, their jumps are a fascinating and entertaining display of their athleticism.

The striped dolphin is listed as 'Least Concern' on the IUCN (International Union for Conservation of Nature) Red List.
This means that they are not currently endangered. However, their population may be declining due to marine pollution, bycatch from fisheries, and collisions with ships. To protect striped dolphins, it is crucial to protect the marine environment.
