(21) Why animals help each other - Ashley Ward

Humpback Whale Migration

• Humpback whales migrate thousands of kilometers annually.

• They travel from tropical breeding grounds to colder feeding grounds, seeking rich feeding areas.

Unexpected Altruism

• During migration, some humpback whales display altruistic behavior.

• One whale, upon hearing distress calls from a seal being harassed by orcas, decides to intervene.

• The humpback whale charges at the orcas, which are 8 meters long, using its massive pectoral flukes to drive them away.

• After ensuring the seal's safety, the whale resumes its migration journey.

Understanding Whale Behavior

• This behavior raises intriguing questions about altruism in nature.

• Why expend energy and take risks to save an unrelated creature?

• Such acts challenge the notion that nature is purely about survival of the fittest, suggesting a more complex social structure among some marine species.

The Role of Altruism in Nature

• Charles Darwin's "On the Origin of Species" popularized the idea of "survival of the fittest."

• However, instances like the humpback whale's rescue show that there can be room for altruism in evolutionary survival strategies.

• These events may serve a broader ecological purpose or support social bonds and altruistic behaviors among marine mammals.
