This Intelligent Marine Species Uses Seaweed to Groom and Relax

The ocean never fails to surprise, and this time, the spotlight is on orcas, popularly known as killer whales. Famous for their sharp intelligence and strong social bonds, these marine mammals have now revealed yet another fascinating side. Scientists have discovered that some orcas use kelp, a type of seaweed, as a tool to massage one another, an unusual and rare behavior in the wild.

The Discovery That Turned Heads

Interestingly, orcas are not whales at all. They are the largest members of the dolphin family, which makes this discovery even more intriguing. According to a recent study published in Current Biology, researchers observed orcas biting off long strands of kelp, carefully placing them over the backs or sides of other pod members, and gently rubbing them back and forth. The motion closely resembles a massage.

Why Are Orcas Doing This?

Marine biologists believe this behavior may serve multiple purposes. One theory suggests it could help maintain skin health by removing parasites or soothing irritation. Another idea is that it helps orcas relax and reduce stress. Some experts also think it’s simply a playful social activity that strengthens bonds within the pod.

A Name for the Behavior

Professor Darren Croft from the University of Exeter and the Center for Whale Research has dubbed this behavior a “kelp massage.” Scientists have also named it “allokelping,” a term inspired by “allogrooming” seen in primates, where animals groom each other to clean, bond, and socialize.

Tool Use in the Ocean: A Rare Sight

Tool use in animals is rare, especially in marine life. While chimpanzees use sticks to catch termites and crows use twigs to find insects, seeing marine mammals use objects in a non-hunting, social context is groundbreaking.

A Culture Beneath the Waves

Orcas live in close-knit pods that function much like families. They communicate through distinct calls, work together while hunting, and pass down behaviors from one generation to the next. Young orcas often learn by watching elders, much like humans learn traditions and skills.

The Ocean Still Has Secrets

This discovery adds another layer to what we know about orcas and reminds us how little we still understand about life beneath the waves. Intelligent, social, and now seemingly self-care enthusiasts, orcas continue to prove that the ocean is full of wonders waiting to be uncovered.
