Confocal laser scanning microscopy of female Osedax “nudepalp E”. Depth coded images (in D-F) 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 Overview, dorsal view (blue, acetylated α-tubulin IR; red, serotonin LIR). b Anterior end, dorsal view (green, phalloidin; blue, acetylated α-tubulin IR; red, serotonin LIR). c Anterior end, lateral view (blue, acetylated α-tubulin IR; red, serotonin LIR). d Brain, ventral view (depth coded colors, serotonin LIR). e Anterior end, dorsal view (depth coded colors, acetylated α-tubulin IR). f Anterior end, ventral view (depth coded colors, acetylated α-tubulin IR).
