Abstract: The blood glucose concentration of Cryptochiton stelleri was found to be 3.5 +/- 2.0 mg % with no significant difference between the sexes. The chitons were observed to rapidly counteract increases in their blood sugar brought about by glucose injection. In an attempt to elucidate the regulatory mechanism involved in maintaining Cryptochiton's relatively constant blodd sugar concentration, the effect of infusing vertebrate insulin, norepinephrine, and serotonin was monitored. None of the hormones used appeared to have any affect on the chiton's blood sugar concentration.
