I can’t believe that I only just learned about the glorious symbiosis between boxer crabs and anemones. The crabs hold one tiny anemone in each claw, and they use the anemones to defend themselves from predators. The anemones benefit from increased access to food because they’re constantly being waved about.
LOOK AT THIS FACE!
And look at these dance moves!
That tiny cheerleader’s got game.
I’m in love.
