Cuttlefish love shrimp. In fact, when given a choice whether to eat crab and shrimp multiple times in the day, they would always choose shrimp. What’s more, these cuttlefish would rather wait for their beloved food if they knew it was coming. These are the two things that the team led by the University of Cambridge, found out.
