I’ve been trying to figure out how to write about this for a few weeks. There is a new type of predation, practiced by sea slugs called “kleptopredation”.
These psychedelic slugs eat hyrdroids, and will pop polyps off the hydroid as one might pick flowers off a stalk. But a new paper suggests that sea slugs prefer to eat hydroids that have just caught plankton.
Think of it like a bear. You (a human) just caught some salmon while fishing in Alaska (I hear it’s the thing to do there). And said bear sees this and waits for you to eat your fish before swooping in to eat you both. It’s two meals for the price of one. A little human-salmon combo meal.
These sea slugs are doing the same thing. So as you head home for Thanksgiving, potentially to eat a turducken, think about how you might be practicing some kleptopredation your self. And if you want to know more, read about it here.
