Longfin inshore squid by ZEISS Microscopy on Flickr.
Juvenile of the Longfin inshore squid, Loligo pealei, stained with anti-acetylated tubulin (green), phalloidin (F-actin, red), and Hoechst (nuclei, blue). The F-actin staining (red) reveals the musculature of the mantle; and the acetylated-tubulin staining (green) reveals the tufts of cilia on the surface of the mantle and rest of the body.
