In order to remove the parasites on my body, I choose to "stick" with sharks

Brother Shark, come and stick with me!

(This sticking is actually the yellowfin tuna/Thunnus albacares using the rough shield scales of the great blue shark/Prionace glauca to scrape off the parasites on the body surface, a bit like wild boars and bears rubbing against trees, but because there is really nothing to rub against in the open ocean, so "sticking" with the rough skin of sharks has become the best way for them to remove parasites on the body surface~

In some fish, similar causes of sticking may also occur between them and other fish, turtles, and rays, while in other fish species, such sticking also occurs frequently within each species.

Sure enough, it’s not just us humans who like to stick on the stickers, fish also think that sticking on the stickers is good for physical and mental health hahahaha…
