Hi! Otters sure are cute. I'm sure it must feel really good to scratch that itch 😁There is a much more important reason to otters rolling in the sand though: grooming. Otters need to groom their fur to maintain a layer of trapped air. Minute spaces between the hairs trap air effectively. This layer of air together with sebaceous secretions on their skin helps with repelling water as well as insulation.
That's so cute! Is he scratching himself or does this just feel good to him?
