Orcas, also known as killer whales, are apex predators which means that they will hunt and kill most marine animals. 

Their diet consists of seals, sea lions, fish, dolphins, whale calves, and even great white sharks. 

They are expert hunters who use their speed, intelligence, and numbers to capture their prey. Orcas hunt in pods and continue to adapt their hunting strategies. 

While most marine animals do their best to flee approaching orcas, humpback whales are heading straight towards the pods to protect animals - many times that are not even their own kind. 

Humpback whales to the rescue

Humpback whales have been seen using their bodies to protect seals and other animals from orcas.

Adult humpbacks are twice as long and several times heavier than an orca. In addition to their size, their powerful flukes and pectoral fins can do some serious damage and even kill orcas.

Mother humpback whales will furiously defend their calves from orcas, but why are humpback whales coming to the rescue of other animals? 

In a study, scientists observed 115 orcas hunts around the world and found that humpbacks intervened in nearly 90% of them, even though most of the time it was to protect another species. 

Some scientists believe it is instinct to defend their calves when they hear the echolocation clicks from the hunting orcas.

One observer recalled, "I remembered thinking that humpbacks can be fearsome if necessary. The trumpeting noise and quick forceful movements, directly at the Orcas, was impressive."

Others think that it may be empathy and altruism. What do you think?

How You Can Help Marine Animals

Billions of pounds of plastic – including fishing gear - enter our oceans each year, and this can have serious impacts on the health of marine life.

Countless dead whales and marine animals have washed ashore with bellies full of plastic. Join us in protecting oceans for all who call them home by donating here.
