Editing Cavitation (section)

===Marine life===
Just as cavitation bubbles form on a fast-spinning boat propeller, they may also form on the tails and fins of aquatic animals. This primarily occurs near the surface of the ocean, where the ambient water pressure is low.

Cavitation may limit the maximum swimming speed of powerful swimming animals like [[dolphins]] and [[tuna]].<ref>{{cite magazine | last = Brahic | first = Catherine | title = Dolphins swim so fast it hurts   | magazine = New Scientist | date = 2008-03-28 | url = https://www.newscientist.com/channel/life/dn13553-dolphins-swim-so-fast-it-hurts.html | access-date = 2008-03-31}}</ref> Dolphins may have to restrict their speed because collapsing cavitation bubbles on their tail are painful. Tuna have bony fins without nerve endings and do not feel pain from cavitation. They are slowed down when cavitation bubbles create a vapor film around their fins. Lesions have been found on tuna that are consistent with cavitation damage.<ref name="IosilevskiiWeihs2008">{{cite journal|last1=Iosilevskii|first1=G|last2=Weihs|first2=D|title=Speed limits on swimming of fishes and cetaceans|journal=Journal of the Royal Society Interface|volume=5|issue=20|year=2008|pages=329–338|issn=1742-5689|doi=10.1098/rsif.2007.1073|pmid=17580289|pmc=2607394}}</ref>

Some sea animals have found ways to use cavitation to their advantage when hunting prey. The [[pistol shrimp]] snaps a specialized claw to create cavitation, which can kill small fish. The [[mantis shrimp]] (of the ''smasher'' variety) uses cavitation as well in order to stun, smash open, or kill the shellfish that it feasts upon.<ref>{{cite web|last=Patek|first=Sheila|title=Sheila Patek clocks the fastest animals|url=http://www.ted.com/talks/sheila_patek_clocks_the_fastest_animals.html|publisher=TED|access-date=18 February 2011}}</ref>

[[Thresher sharks]] use 'tail slaps' to debilitate their small fish prey and cavitation bubbles have been seen rising from the apex of the tail arc.<ref name="TsiklirasOliver2013">{{cite journal|last1=Tsikliras|first1=Athanassios C.|last2=Oliver|first2=Simon P.|last3=Turner|first3=John R.|last4=Gann|first4=Klemens|last5=Silvosa|first5=Medel|last6=D'Urban Jackson|first6=Tim|title=Thresher Sharks Use Tail-Slaps as a Hunting Strategy|journal=PLOS ONE|volume=8|issue=7|year=2013|pages=e67380|issn=1932-6203|doi=10.1371/journal.pone.0067380|pmid=23874415|pmc=3707734|bibcode = 2013PLoSO...867380O |doi-access=free}}</ref><ref>Archived at [https://ghostarchive.org/varchive/youtube/20211205/lHoCCPsRuhg Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20130825141415/http://www.youtube.com/watch?v=lHoCCPsRuhg&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web| url = https://www.youtube.com/watch?v=lHoCCPsRuhg| title = THRESHER SHARKS KILL PREY WITH TAIL | website=[[YouTube]]| date = July 12, 2013 }}{{cbignore}}</ref>
