Christopher Taylor at the Catologue of Organisms (one of the handful of blogs I rush to when I see an update in my Reader!) has a post on a really unique reproductive strategy in polychaetes, called epitoky, in the awesomely titled My Genitals Just Grew Eyes and Swam Away. Its quite astonishing, especially the bit about the sponge dwelling syllid!
Chris Mah from the Echinoblog just can’t get enough echinosex so he’s posted more video’s of echinoderms having sex!
