Text Appearing Before Image:
LIFE CYCLE OF CORYMORPHA BIGELOWI 491 seen to feed on brine shrimp nauplii and did not live for more than a few days. The newly released medusae are similar in size to the smaller individuals described from plankton collections by Kramp (1928) and Browne (1916). It is of interest to note that in these collections small individuals (1.25 to 1.5 mm high) have subterminal nematocyst bulbs on the primary tentacle which are absent on the newly released Euphysora bigelozvi medusae. In Coryinorpha nutans the annular subterminal bulbs are developed even before liberation from the polyp (Russell, 1953).
