FYI

October 2012, the month priapulids suddenly became newsworthy!

a comment on: "Deuterostomic Development in the Protostome Priapulus caudatus" José M. Martín-Durán and others. Corrected proof at Current Biology

"... gastrulation in the conservatively evolving protostome P. caudatus follows strictly a deuterostomic pattern"

Dear All,

As I doubt priapulids have a list of their very own, and as they are worms in appearance and co-occur with annelids, perhaps this news story from the UK on priapulids should circulate to us. Just shows what you can make a press release out of, and have it read worldwide.  The article itself appears to be fairly turgid going, but maybe it will enlighten in some aspect.  After all, the press item concludes, "Ultimately, combined results from these investigations will offer a solid framework for understanding the very roots of Life's grandeur and the astounding variety of species alive today."
