Streamlined objects reduce drag, allowing for smoother movement through air or water. By minimizing resistance, the object can move more efficiently and at higher speeds. Additionally, streamlined designs can help improve stability and control during travel.
Sea otters are the only species in their genus, Enhydra. However, there are thirteen species of otter in the subfamily Lutrinae; these include the Marine otter, the North-American river otter, the Neotropical river otter, the Southern river otter, the Eurasian otter, the Hairy-nosed otter, the Asian small-clawed otter, the African clawless otter, the Congo clawless otter, the Giant otter, the Smooth-coated otter, the Spotted-necked otter, and (of course) the Sea otter.
The most common features in modern cars that help to reduce air friction is the streamlined design of the bumpers and spoilers. The streamlined shape of fast cars also helps to reduce drag.
