Orca

✨ The wolf of the seas

The orca, also known as the killer whale, is the largest member of the dolphin family. It lives in every ocean, from tropical seas to the icy waters of the Arctic and Antarctica. Adults can reach about 9 meters in length and weigh more than 6 tonnes, with males generally larger than females. Its striking black-and-white coloration makes it easy to recognize, while its streamlined body and powerful tail allow it to swim at speeds of up to 56 km/h over short distances.

Orcas are highly intelligent animals that communicate using whistles, clicks and pulsed calls. Different populations have distinct vocal dialects and hunting traditions that are passed from one generation to the next, making them one of the few animals known to possess cultural behaviors. Depending on where they live, their diet may include fish, squid, seals, sea lions and even large whales.

Orcas live in stable family groups called pods, usually led by older females. These close social bonds help them cooperate while hunting, caring for calves and defending one another. Their hunting techniques vary between populations and often involve remarkable teamwork, such as creating waves to wash seals from floating ice or surrounding schools of fish before feeding.

Females give birth to a single calf after a pregnancy lasting around 17 months, and young orcas may remain with their mothers throughout their lives. Although the species is widespread, some populations are threatened by pollution, declining prey, underwater noise, fishing activities and climate change. Protecting marine ecosystems is essential for ensuring the long-term survival of these highly social predators.

💡 Did you know?

The orca is nicknamed the 'wolf of the seas' because it hunts in a very strategic team. To catch a seal on a piece of ice, for example, several orcas can swim together towards it to create a large artificial wave that will tip the seal into the water. They speak to each other with complicated sounds to coordinate their movements like a real sports team!

Did you know that each group of orcas has its own 'language'? Scientists have discovered that orca clans use different whistles and clicks depending on their region. It's as if they have different accents or dialects, like humans! A baby orca learns the language of its mother and its clan for several years to communicate properly.

Orcas are animals very attached to their families. They spend their entire lives with their mother and siblings. Orca grandmothers play a very important role: they know the best places to find food and teach migratory routes to the youngest. It is a very organized society where everyone helps each other to survive in the ocean.
