Zoanthid Histology

I uploaded some histology of a new zoanthid for collaborators in Japan to look at. Flickr is a great tool for sharing images and now I've found a work-related use for it! I don't have anything labeled but the descriptions for each image tell you what it is. The blue globby things are forams. Zoanthids are known to incorporate sand and sediment into their body wall to make them more rigid. As you can see from some of the cross sections, the mesenteries have very weak musclature. The staining protocol I used is called Masson's trichrome. Red stains for acidic tissues, like muscle fibers, while blue stains for basic tissues, such as connective tissue.
