What does syndactylous mean?
Syndactylous is an adjective meaning that two or more digits are joined or fused together. The term is used in medicine and zoology for hands, feet, toes, or fingers in which the usual separation is absent, either because of soft tissue, cartilage, or bone joining them. It may describe a congenital condition in humans or a natural anatomical feature in animals. The word is related to syndactyly, the condition itself, and should not be confused with polydactylous, which means having an unusually large number of digits rather than joined digits. Although syndactylous is largely technical, it is useful when precision matters because it identifies the specific way in which digits are connected without implying that an extra digit is present.
