Killer whales make kelp tools to 'massage' each other

The news article reports that killer whales, also known as orcas, have been observed using kelp as a tool to massage each other. Researchers have captured footage of these intelligent marine mammals carefully selecting and manipulating pieces of kelp to gently rub against their bodies, suggesting a sophisticated social behavior. The article highlights that this behavior is a unique example of tool use among orcas, which are known for their complex social and cognitive abilities. Researchers believe the orcas use the kelp to alleviate itchiness or muscle tension, indicating a level of self-awareness and the ability to empathize with the needs of their pod members. The discovery provides further insights into the remarkable intelligence and social dynamics of killer whales, and underscores the importance of continued research and observation to better understand the behaviors and capabilities of these charismatic marine predators.
