As a phyllosoma, another word for lobster larvae, the crustaceans like to kick back and relax, hitching rides on Moon jellyfish instead of using their own legs to get around. What's more, they never really have to get off because they also eat the jellyfish. It's like taking an Uber everywhere, only the car is made out of chocolate. But how do lobsters survive on their deadly hosts? The answer could help make it easier to keep lobster on the menu.
