What is the world's largest type of dolphin?

The world's largest type of dolphin is the orca or killer whale (Orcinus orca), which is often considered a member of the dolphin family. Orcas are found in oceans all over the world, from the Arctic to the Antarctic. They can grow up to 9 meters long and weigh up to 10 tonnes. Despite their name, they are not true whales but the largest members of the dolphin family. They are highly intelligent and social animals, living in large groups called pods.

Orcas are apex predators, at the top of the marine food chain. They are known for their hunting abilities, preying on a variety of animals, including fish, squid, sea birds, and even other marine mammals such as seals and smaller dolphins.

While orcas are a highly intelligent and fascinating species, they face many threats in the wild, including habitat loss, pollution, and overfishing of their prey. Conservation efforts are underway to protect these amazing animals and their marine habitats, including through marine protected areas and stricter regulations on commercial fishing.
