Etymology: Heteromorphic is a built-to-order scientific term, assembled from two Greek roots that were never combined in antiquity. The first, "heteros," meant "other" or "different," and the second, "morphē," meant "form" or "shape." Greek speakers used these separately; the compound belongs to modern scientific vocabulary, which routinely borrowed classical parts to name things the ancients had no reason to name. The English suffix "-morphic" follows the same pattern. It comes from the Greek "morphē" through the adjective-forming ending "-ic," which passed through Latin "-icus" and Old French "-ique" before reaching English. Words in "-ic" like this one are typically adjectives describing something as having a particular form. The meaning fits the parts neatly: "hetero-" supplies the idea of difference, and "-morphic" supplies form. A heteromorphic species is one in which distinct forms coexist, whether as different appearances of adults, or as separate forms at different life stages.
