A new Circus of the Spineless, and a call for submissions for the next

As is traditional at the end of the month, a new Circus of the Spineless is up at The Voltage Gate. And the next Circus of the Spineless at the end of February will be…here! Start sending me good stuff on invertebrate organisms—remember, there are over 30 animal phyla, and all but one of them are fair game, and even that one contains non-vertebrate classes. Will we be able to get them all represented?
