What does aliped mean?
Aliped is a rare zoological term for an animal whose feet are adapted for swimming. Seals and penguins are standard examples, although the term can be used more narrowly to describe the feet themselves. In ordinary writing, “aquatic animal” or the appropriate species name will usually be clearer than “aliped,” which has the air of a technical classification or label. The word has an unexpected history: it comes through New Latin from Latin alipēs, formed from āla, meaning “wing,” and pēs, meaning “foot,” and therefore literally means “wing-footed.” That original image does not correspond closely to the modern swimming-related sense, but it gives the word a memorable and slightly paradoxical history. Aliped remains useful in zoological, anatomical, and taxonomic contexts where precision about the form and function of an animal’s feet matters.
An animal whose feet are adapted for swimming, especially a seal or penguin.
"The exhibit includes several alipeds, such as seals and penguins."
A specialized zoological noun, uncommon outside scientific or educational contexts.
Having feet adapted for swimming.
"The penguin is an aliped bird adapted to life in the water."
Usually appears in technical descriptions of animals and their anatomy.
The standard plural of the noun is “alipeds.”
"The exhibit compares alipeds such as seals and penguins."
Its Latin ancestor literally meant “wing-footed,” although modern English uses aliped for animals built for swimming.

Where does aliped come from?
Aliped was formed in English from Latin alipēs, a compound of āla (“wing”) and pēs (“foot”), literally “wing-footed.” In modern zoological use, the word refers to an animal with feet adapted for swimming. Its Latin form was also taken into New Latin, from which the English zoological sense developed.

How aliped is actually used
This is specialized zoological vocabulary and is uncommon in general prose. In modern usage, it refers specifically to the adaptation of the feet, not merely to an animal's aquatic habitat, and it is not a general synonym for “aquatic animal.”
