Symbiotic Relationships in Animals: Types and Examples

The video introduces symbiotic relationships in animals, which are interactions between different species living closely together. It covers three main types: mutualism, where both species benefit; commensalism, where one benefits without affecting the other; and parasitism, where one benefits at the expense of the other. Examples include cleaner fish and larger fish, barnacles and whales, and tapeworms in mammals. The video also shares fun facts about unique symbiotic relationships like oxpecker birds and rhinos, and clownfish and anemones.

What is a symbiotic relationship in animals?

• A relationship where animals hunt each other

• A relationship where animals compete for resources

• It becomes extinct

• It is neither helped nor harmed
