Do Earthworms Meet for Drinks After Work?

More evidence that animals are much smarter than we know: the BBC Earth News reports on research that shows that earthworms respond to social cues and prefer to travel in groups. 



  1. I question whether intelligence is the correct term for critters that crawl far enough onto pavement in the rain that they can’t get back before it dries out and they die.

  2. I’ve noticed earthworm clustering in my worm box, which always led me to believe there was some sort of deliberate social interaction going on, even if it’s only instinct-based. Besides, don’t they mate with each other? Even if it’s random and not how we mammals think of mating, it seems like some kind of social interaction.

  3. So, is a group of earthworms called a wriggle? “Herd” just doesn’t seem righ. As an avid reader of natural history, I thank you for posting this–and yes, I’ve read Amy’s book on earthworms!

  4. @Dave — we use “intelligence” to describe human beings and yet there are all those Darwin Awards… 😉 Sorry, I couldn’t resist! No snarkiness intended.
