Chiridota

Eschscholtz, 1829

34 species

Tentacles 12 exceptionally 13 or even 14. Digits 3-10 on each side, the terminal pair the longest. Number of digits on the tentacle may be odd, but examination will show that this is due to an extra digit on one side of the base of the series. Polian vesicles numerous. No gustatory organs known to occur. Ciliated funnels usually single, sometimes collected into little groups but not forming true stalked clusters. Calcareous deposits in the form of 6 spoked wheels collected into little papillae containing 10-80 of diverse sizes; no sigmoid deposits, but small curved rods with enlarged ends are often present and minute miliary granules, or somewhat larger rod shaped particles, frequently occur in connection with the longitudinal muscles. (Clark, 1907)

Tentacles 12, digits 2-10 on each side terminal pair longest. Polian vesicles numerous 3-20. No gustatory organs known to occur. Ciliated funnels usually single, but when many, not forming true stalked clusters. Calcareous deposits 6 spoked wheels, collected in little papillae, containing 10-80 of diverse size. No sigmoid bodies, but small curved rods with enlarged ends are often present and minute oval miliary grains, or somewhat large rod shaped particles frequently occur in connection with the longitudinal muscles. (Mortensen, 1927)

Tentacles 12. Polian vesicles numerous. Deposits 6 spoked wheels aggregated into papillae. No sigmoid deposits, but small curved rods with enlarged ends may be present; and minute lenticular bodies may occur in longitudinal muscles. (Pawson, 1970)
