Is it more correct to say Lions live in family groups are prides instead of Lions live in family groups called prides?

Both phrases convey the same idea, but the first option, "Lions live in family groups are prides," contains a grammatical error and is less clear. The second option, "Lions live in family groups called prides," is more accurate and grammatically correct. It clearly indicates that the term "prides" refers to the family groups in which lions live.
