[[File:PacificWhiteSidedDolphine.jpg|thumb|Pacific white-sided dolphins porpoising.]]
Dolphins frequently leap above the water surface, this being done for various reasons. When travelling, jumping can save the dolphin energy as there is less friction while in the air.<ref name=Weihs>{{cite journal|last=Weihs|first=D.|title=Dynamics of Dolphin Porpoising Revisited|journal=Integrative and Comparative Biology |year=2002| volume=42| issue=5| pages=1071–1078| doi=10.1093/icb/42.5.1071| pmid=21680390|doi-access=free}}</ref> This type of travel is known as porpoising.<ref name=Weihs /> Other reasons include orientation, social displays, fighting, [[non-verbal communication]], entertainment and attempting to dislodge [[parasite]]s.<ref>David Lusseau (2006), ''Why do dolphins jump?

Dolphins show various types of playful behavior, often including objects, self-made [[bubble ring]]s, other dolphins or other animals.<ref name="Walker2007">{{Cite book|last=Walker|first=Sally M. |title=Dolphins|url={{google books|plainurl=y|id=5Buh9FtAG8AC|page=6}}|date=November 2007|publisher=Lerner Publications|isbn=978-0-8225-6767-7|pages=6, 30}}</ref><ref name=dolphinplay>Robin D.

Playful dolphin interactions with humans are the most obvious examples, followed by those with [[humpback whale]]s and [[dog]]s.<ref>Mark H. Deakos et al.
