Finless is an adjective that refers to an object or organism that lacks fins. This term is commonly used in the context of aquatic animals, particularly fish or cetaceans, as well as various watercraft or vehicles designed for water navigation.
In the realm of biology and zoology, finless typically denotes an organism that does not possess or exhibit any fins. Fins are appendages found in many aquatic animals that aid in movement, balance, and steering in water. By lacking fins, an organism may have adapted alternative mechanisms or structures to compensate for the absence of these appendages.
When applied to watercraft, such as boats or submarines, finless signifies the absence of any protruding or extended fins. Fins are often included in the design of water vehicles to enhance stability, control, and maneuverability. However, finless vessels may utilize other technological advancements or engineering features to achieve similar functions.
Moreover, the term finless can also denote something that is devoid of any fin-like protrusions or features. In this broader sense, it may extend beyond the aquatic realm and be used to describe any object or entity lacking fin-like attributes, such as a finless aircraft or a finless car.
In summary, finless is an adjective used to describe the absence or lack of fins in various contexts, including biological organisms, watercraft, and other objects.

The word "finless" is derived from the combination of two English word roots: "fin" and "less".
The term "fin" refers to a flat or thin appendage that is used by fish for swimming and balance. Fins are found on various aquatic creatures, such as sharks, fish, and dolphins.
The suffix "-less" is used in English to denote the absence or lack of something. It is derived from the Old English word "leas", meaning "without".
So, when we combine "fin" and "-less", we get "finless", meaning "without fins" or "lacking fins". This word is commonly used to describe certain animals or objects that naturally lack fins or have lost them due to adaptation or physical modification.
