Masters Research - Urechis caupo - This study conducted by Jeff Judd at San Francisco State University was a general survey of the natural history, feeding and digestive physiology of Urechis caupo, the fat innkeeper worm.Introduction to the Echiura - Introduction to this small phylum, closely related to the Annelids, from UCMP Berkeley.
Minor Invertebrate Phyla - Echiura - Echiurans are marine worms that burrow into mud or sand or live in empty shells.
Life with Toxic Sulfide - A talk by Alissa Arp about Hydrothermal Vents, Deep Sea Vents, Seeps and Estuarine Mud--Life with Toxic Sulfide - Taxa included are Pogonophora and Echiura
Echiura - Devolopment of the nervous system and phylogenetic implications - Immunohistochemical analysis (cLSM) of the development and organization of the nervous system in Echiura and the phylogenetic implications of these results. The work of Rene Hessling shows volume rendered three-dimensional reconstructions of the central nervous system of Bonellia viridis. The results suggest that the Echiura do not form a distinct phylum but should be consided as a subtaxon of Annelida.
