Clownfish do a wiggle dance to increase seawater circulation to their sea windflower hosts , helping the sea animal breathe , a new study suggests .
The findings , bring out today ( Feb. 27 ) in the Journal of Experimental Biology , evoke theclownfishand sea anemone relationship may be more of a two - way street than antecedently thought . ( Clownfish live in the wavy tentacles of ocean anemones , stationary brute that typically live on the seafloor or coral reefs and are related to coral and jellyfish . )
Clownfish perform a wiggle dance that increases oxygen flow to their hosts, sea anemones
" This is the first fourth dimension we ’ve ever discovered that the clownfish can actually help the sea anemone to suspire and can help them to aerate themselves , " said study co - author Nanette Chadwick , a marine life scientist at Auburn University .
It also advise that anemones can live in so many home ground in part because of the clownfish . Anemones can thrive in stagnant water becauseclownfishdances , in which they pother their flipper while dodging and become while nestle deep in the anemone , circulate the urine for the creatures , furnish them with needed oxygen , Chadwick said .

One - fashion street ?
It ’s long been known that the extremely conspicuous , neon - colored clownfish would be lost without its windflower home . They ca n’t swim very tight and are often gobbled up bypredatory fishsuch as grouper or barracuda as before long as they venture outside of the refuge , Chadwick told LiveScience .
The sea anemone also bring forth a toxin that deters clownfish predators . The orange - and - white fish avoids the toxin by slather itself in sea anemone mucus . The windflower sees the Pisces the Fishes as part of itself and lets clownfish shelter between its tentacle .
Until now , most scientists think the benefits went one path — from anemone to clownfish .
But Chadwick and her colleagues inquire whether , likecoral fishand other fish species , the clownfish also benefit the ocean anemones , by give vent them .
To find out , the squad gathered ocean anemone and clownfish from the Red Sea near Aqaba , Jordan , and put them in a flow tank to see how much oxygen they used , both singly and together .
Together , the two coinage used up more atomic number 8 than either could on their own . But the two had to be touching for this to happen , Chadwick said .
Wiggle dancing
To realize why , the team spend hours filming the behavior of the clownfish within thesea anemone .
It work out the clownfish perform a bizarre littlewiggle saltation , flapping its fin while dodging and turning .
" That is likely kind of screw up up the sea anemone , " Chadwick said .
That creates fresh water circulation for the stationary anemone , allow it to get at more oxygenated water , accelerate up its metabolism , and grow faster . That ’s also good news for the clownfish , which have more way to blot out within the anemone .
preservation implication
The finding have implications for the tropical fish trade , Chadwick articulate . Typically , fisher harvest all the clownfish in an anemone .
But when they do that , " they doom the windflower to exit , " she said .
alternatively , fisherman should take just one or two clownfish while leaving the others to ventilate the anemone .
Of naturally , the most sustainable approach shot would be to buyaquarium fishthat were grown in a lab or aquaculture — leaving all the anemones and the clownfish alone , she state .
