Encounter between a solitary wild dolphin and human children in 1967. Educational anthropologist Dr. Betsy Smith of Florida International University is usually credited with starting the first line of research into dolphin-assisted therapy in 1971, building on earlier research by American neuroscientist Dr. John Lilly on interspecies communication between dolphins and humans in the 1950s.

Some predators, such as dolphins, hunt in groups of their own. One technique employed by many dolphin species is herding, where a pod will control a school of fish while individual members take turns ploughing through and feeding on the more tightly packed school (a formation commonly known as a bait ball). Corralling is a method where fish are ...
The Centers for Disease Control and Prevention (CDC) recommends swimming lessons for children from 1–4, along with other precautionary measures to prevent drowning. [4] In 2010, the American Academy of Pediatrics reversed its previous position in which it had disapproved of lessons before age 4, indicating that the evidence no longer supported an advisory against early swimming lessons.

Surface-living animals (such as sea otters) need the opposite, and free-swimming animals living in open waters (such as dolphins) need to be neutrally buoyant in order to be able to swim up and down the water column. Typically, thick and dense bone is found in bottom feeders and low bone density is associated with mammals living in deep water.
The dolphin kick is named for its resemblance to the motions made by a swimming dolphin. It is typically used in competitive swimming immediately after a swimmer enters the water or after turns. The swimmer performs the kick by moving both legs together, vertically, which sends a wave through the swimmer's body, propelling them forward.
The common dolphin (Delphinus delphis) is the most abundant cetacean in the world, with a global population of about six million. [3] Despite this fact and its vernacular name, the common dolphin is not thought of as the archetypal dolphin, with that distinction belonging to the bottlenose dolphin due to its popular appearances in aquaria and the media.
