He had a fishman and a guy from horned race as his commanders
He has horned race , fishman and winged race under him and probably more now that he is a Yonko.
Big Mom similarly has Homies, Pekoms( a talking lion capable of turning into a tortoise) and Tamago (long-legged person capable of turning into a chicken), Bobbin (a wide-faced mask-wearing man), Randolph( an anthropomorphic rabbit who rides a crane), Pudding( hybrid between a human and a member of the Three-Eye Tribe) making her crew one of the most diverse.
Kaido has lot of different races like horned race etc..
We don’t see anyone from different race.Probably Shanks doesn’t take anyone from different race in his main ship.
