Why Do Some Whales Have Fins

Why Do Some Whales Have Fins. These naturally occurring biological features that help the animal to overcome drag and hydrodynamic difficulties have been widely applied to all sorts of aircraft and wind turbines to help them overcome aerodynamic difficulties as well as improve efficiency. In some species these are used to help support reproductive organs.

All captive adult male orcas have collapsed dorsal fins, likely because they have no space in which to swim freely and are fed an unnatural diet of thawed dead fish. Dorsal fin collapse in orcas in the wild is typically associated with emaciation (the state of being abnormally thin or weak) and/or anthropogenic (human) causes, such as entanglement in fishing gear, bullet wounds or exposure to oil spills (baird and gorgone 2005).

All baleen whales have small dorsal fins set far back on their bodies, and all dolphins have larger ones (relative to body size) closer to the middle of the body. Although some faster species such as sei, bryde’s, and fin whales will breach, they do it less often than slower whales such as humpbacks, bowheads, gray whales, sperm whales, and right whales.
