Didactylous is an adjective that describes an animal having two digits or toes on each limb or foot. It is derived from the Greek words "di-", meaning two, and "daktylos", meaning finger or toe. This term is mainly used in the field of zoology to classify certain species based on their specific physical characteristics.
Organisms classified as didactylous typically possess limbs or appendages, such as feet, hands, or wings, that are composed of two distinct digits. This can be observed in various creatures, including certain birds, primates, and lizards. For instance, a didactylous bird may have two well-developed and functional toes, which allow it to perch or grasp objects with precision. Similarly, didactylous primates, like humans, possess hands that consist of two digits - the thumb and fingers - enabling them to manipulate objects effectively.
The didactylous characteristic has evolved in different species to adapt to their specific environments and lifestyles. The existence of two digits provides increased dexterity, allowing animals to engage in complex tasks or behaviors. This anatomical feature also enhances locomotion by promoting stability and enabling a greater range of movement.
Overall, the term didactylous serves as a scientific descriptor for animals possessing two digits on each appendage. Its usage aids in classifying and understanding the diverse adaptations and attributes found across the animal kingdom.
Having two fingers or toes.

The word "didactylous" is derived from the combination of two Greek roots: "didaktulos" and "daktulos".
The root "didaktulos" (διδακτυλος) comes from the Greek words "didaskein" (διδασκειν) meaning "to teach" and "daktulos" (δακτυλος) meaning "finger" or "toe".
Therefore, "didaktulos" can be translated as "teaching finger" or "teaching toe", referring to the fact that certain animals have only two functional digits or fingers/toes.
When combined with the prefix "di-" meaning "two", "didaktulos" becomes "didactylous", which is used in the context of zoology to describe animals that have two functional digits.
