User blog:CNBA3/Espadas Physiology

So we know that Ulquiorra is a bat hollow, Grimmjow a panther hollow, Stark a wolfish/cowboy/pimp/thing hollow (or can we asume that he is more wolf, Barrigan a skeleton hollow, Harribel a shark hollow, and Nnoitra a mantis hollow.

But what of the other Espada, Szayel Aporro, Zomarri, Aaroniero, Yammy? what would their Physiologies be?

Please post for info or ideas!
