Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole. [1] Cetacean stranding has occurred since before recorded history. [2]
Large whales tend to lobtail by positioning themselves vertically downwards into the water and then slapping the surface by bending the tail stock. Dolphins, however, tend to remain horizontal, either on their belly or their back, and make the slap via a jerky whole body movement. All species are likely to slap several times in a single session.
The dolphins then hoist themselves onto land — always on their right sides — where they feast on the stranded fish, briefly stranding themselves in the process before wiggling back into the water.
However, the amount of work the scallop has to do is mitigated by the elastic hinge that connects the two shells of the bivalve. Squids swim by drawing water into their mantle cavity and expelling it through their siphon. The Froude efficiency of their jet-propulsion system is around 0.29, which is much lower than a fish of the same mass.

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.
