Do dolphins heal their own wounds?
Scientists think that dolphins rub against coral to treat wounds on their skin. The New Scientist magazine in May 2022 explained that Bottlenose Dolphins appear to look for specific corals and sea sponges that produce anti-bacterial or hormone-like substances, which may indicate that they are trying to heal their own wounds and infections by rubbing against them.
Scientists have observed orcas and Beluga whales rubbing their bodies against underwater sand and pebbles, but similar behaviour in dolpins has not been widely observed.

What is mucous?
Mucous (or mucus) is slimy, slippery, or sticky moisture produced by mucous glands.
Amphibians (such as frogs and toads), fish, snails, and slugs produce mucous on their outer skin. The mucous is protection to keep the animal’s skin moist. Mucous also protects them against diseases and germs.

The Iberian Threeband Slug (Ambigolimax valentianus) is a mollusc in the Limacidae family of air-breathing land slugs; a snail without a shell. It is a terrestrial (land) pulmonate (air-breathing) gastropod (one-footed) mollusc. It is also known as the Greenhouse Slug.
The Iberian Threeband Slug is usually pinkish with two faint narrow or broken bands down its body and mantle (shield on its back, behind its head) with a third midline band on the mantle. It has two pairs of retractable tentacles (feelers) on its head. One pair of tentacles is larger with eyespots on the tips. The lower, or smaller tentacles, provide the sense of smell.

The East African Keeled Land Slug (Limacidae sp.) is an air-breathing terrestrial mollusc in the Gastropoda order and Limacoidea superfamily of keel-backed (ridgeback) slugs. It is a land snail without a shell.
The East African Keeled Land Slug has a long white body with a mantle, a keeled (ridged) back and two pairs of retractable feelers on its head. The upper pair of feelers has eyespots at the tips. The lower pair of feelers contains sense organs. The mantle is a saddle-looking structure behind the head. On one side of the mantle is a respiratory opening, called a pneumostome. The body is also called the tail, which is behind the mantle. It has a ridge down the middle of the back of the tail. Its foot is the flat under-side of the slug. It secretes mucous that it travels on.
