Bora has posted the first Carnal Carnival: The Essentials of Elimination
It's a great collection of posts about poop of all sorts (including my E. chromi post), from humans to sharks to caterpillars to rabbits.
The next Carnal Carnival will be hosted by Carin Bondar at Biologist With a Twist. The theme will be barf.
You can find submission instructions on the Carnal Carnival blog.
