Autoradiograph of specimen of Echinastcr placed for 24 hours in a medium containing glycine-C14, and then kept in sea water for 20 days before sacrifice. As with the other species, the labeled amino acid has been incorporated into the epidermal regions. Other tissues stand out due to their natural coloration. Greater detail of the ambulacral area is shown in Figure 17. 14 X. FIGURE 8. Autoradiograph of transverse section through disk of a specimen of Echinastcr sacrificed 6 hours after being placed in glycin

Autoradiograph of transverse section through disk of a specimen of Echinastcr sacrificed 6 hours after being placed in glycine-C14 medium. While the epidermis has incor- porated a great quantity of the labeled glycine, apparently none of it has entered the mouth and been taken up by the stomach or other tissues. (St, area of stomach tissue.) 8X. FIGURE 9. Autoradiograph of a longitudinal section of a ray tip of a specimen of Echinaster sacrificed 24 hours after being placed in medium containing glycine-C14.
