wallowing

Wallowing is an animal behavior where animals roll around in a sunken, wet area, often mud or soil. This behavior is common among perissodactyls, such as equids (horses, zebras) and rhinoceroses.123

For some animals, wallowing serves as a form of self-grooming and can help regulate body temperature, especially in hot weather. Animals like tapirs are known to bathe and wallow, sometimes entering water when disturbed. While the term "wallowing" can also refer to indulging in emotions, in the context of animal behavior, it specifically describes this physical act of rolling in a substance.32
