New question; I know that some mamono (namely harpies) lay eggs, but how do you tell which ones are supposed to lay eggs or bear live young? If you take into account the classifications of animals, a lot of them have characteristics of multiple types (harpies are mammals and birds, mermaids are mammals and fish, etc.). This causes me some confusion, since humanoids, monstrous or not, are usually bear live young, but some of these lay eggs. Which ones are which?
