Fish FacialIn another case where mealtime doesn’t have to spell demise for one of the parties — except the parasites — this Red Sea parrotfish and the cleaner wrasse on its cheek also enjoy a symbiotic relationship.

It's a fish-eat-fish world out there (or a fish-eat-parasite world). Point is, there's a lot of snacking going on. Be it an opportunistic whale shark that's formed a partnership with fishermen, a painted frogfish using a homemade lure or a team of striped marlin herding prey together, what's for dinner is a question universal to all of us.
