Confocal laser scanning microscopy of female Osedax “yellow collar”. Depth coded image (g) indicate the depth of the signal in the Z-stack: scale follows the colors of the spectral light, the top is to the surface. a Dorsal view (blue, acetylated α-tubulin IR; red, serotonin LIR). b Anterior end, ventral view (blue, acetylated α-tubulin IR; red, serotonin LIR). c Close up of a palp; muscles and nerves (green, phalloidin; cyan, acetylated α-tubulin IR). d Anterior end, dorsal view (anterior end at the left side; red, serotonin LIR). e Anterior end, dorsal view (depth coded colors, acetylated α-tubulin IR). f Cephalon and brain, ventral view (depth coded colors, acetylated α-tubulin IR). g Anterior end, ventral view (depth coded colors, acetylated α-tubulin IR). h Dorso-lateral view (anterior end at the left side; blue, acetylated α-tubulin IR; red, serotonin LIR).
