What is the name for two animals who work together?

There isn't a single, universally accepted term for two animals working together. However, here are some options depending on the context:

General terms:

* Mutualism: This is a biological term for a relationship between two species where both benefit from the interaction.

* Symbiosis: A broader term that encompasses mutualism, but also includes other types of relationships like commensalism (one benefits, the other is unaffected) and parasitism (one benefits, the other is harmed).

* Cooperation: This simply describes the act of working together, regardless of the specific type of relationship.

Specific examples:

* Pack: For wolves, dogs, or other animals that hunt and live together in groups.

* Flock: For birds that travel and forage together.

* Colony: For social insects like ants and bees.

* School: For fish that swim in coordinated groups.

Ultimately, the best term depends on the specific context and the nature of the relationship between the animals.
