Mammals and aquatic animals Venn diagram

This two-set Venn diagram compares mammals and aquatic animals. The left-only region represents the example count for mammals outside the aquatic group, the right-only region represents aquatic animals outside the mammal group, and the overlap represents animals in both. It gives students a simple way to discuss how categories can intersect without treating one category as a subset of the other.

FAQ

Questions fréquentes

What belongs in the overlap?

The overlap contains the examples counted as both mammals and aquatic animals.

Are the counts species totals?

They are illustrative counts for the diagram, not a species inventory.

Can I use named animals instead?

Yes. A Venn region can use short lists when individual examples are more useful than totals.
