Heartless creatures

Everybody in Corsair’s Cove has a heart. Even the guy who’s a little too self-absorbed (you’ll recognize him when you meet him) has mostly good intentions, so I was surprised to read an article in The Economist about a creature that doesn’t.
Instead of a central pump, apparently some sea spiders move oxygen around their bodies with their guts.
However, the species from Friday Harbor, practically next door to the Cove, does have a heart. Of course!
