The Emperor Shrimp is more like a hitchhiker. It rides on the back of a nudibranch (awww jeah) because it likes to wave at all the little people while moving on its gigantic Macy’s day parade float. *princess wave*
Okay, so it’s not exactly like that. The shrimp rides on the back of a giant sea slug, where it picks and cleans its oh-so-smooth skin from parasites and nasties.
Mommy! Let’s ride on the giant sea slug and get free food while we’re at it! Sounds like a good deal to me.
