Orcas Are Using Tools to Clean Themselves
make sense: to be easy to understand or to seem like a good idea
Last year, killer whales were seen wearing salmon on their heads like hats. This year, they’re doing something equally surprising. They are now cleaning each other with seaweed.
Scientists watched drone videos of these whales in the Pacific Ocean. They noticed the orcas breaking pieces of kelp with their teeth. Then, they rubbed the kelp on each other’s bodies, taking turns for as long as 12 minutes. They used their heads and bodies very carefully to hold and move the kelp. This makes the cleaning look planned and thoughtful.
This is not the first time orcas have been seen using kelp to clean themselves. But cleaning each other is something new. It may be a way for the whales to take care of each other and stay healthy.
One scientist, Olaf Meynecke, said, “It totally makes sense to me that they are seeking out anything… to help them with potential reduction in skin infections.”
