What animal is related to isopods?

Isopods are crustaceans, so they are related to other crustaceans, like:

* Lobsters: They have similar body structures and exoskeletons.

* Crabs: They also share a common ancestor and have similar body structures.

* Shrimp: Like isopods, they are small, aquatic crustaceans.

* Barnacles: While they look very different, they are still crustaceans and share evolutionary history.

It's important to note that the relationship isn't as close as, say, a dog and a wolf. They are part of the same broader group, but with many branches and millions of years of divergence.
