Encephalon #83 is at Providentia.
Carnival of Evolution #32 is available at Denim and Tweed.
Finally, Circus of the Spineless #59 is hosted at Shell and Mantle
I’ve got a brain carnival, an evolution carnival, an invert carnival... if I had an ethology carnival, I’d have a personal scientific carnival quadrafecta.
Oh, don’t forget Carnival of the Blue #45 is just a post behind this one!
