RMRDHPH1–. A manual of elementary zoology . Zoology. Plate XIV.—Members of the pelagic fauna, considerably magnified. The animals shown here belong to the plankton or drifting fauna, so called because its powers of swimming are insignificant compared with the strength of the currents of the sea. They derive their food from minute floating plants, and in turn serve to feed larger pelagic animals, such as the great jelly-fish, herrings, and whales. i, Noctiluca.) a large, phosphorescent flagellate ; 2, medusa of a hydroid ; 5, a worm related to Nereis; 6, a crustacean related to Cyclops; 8, the Arrow wor

Individual gastrozooids represent at least relatively permanent components of the active front; they may or may not undergo a gradual replacement cycle. Gonozooids go through a more rapid replacement cycle; individuals occasionally stop advancing with the gastrozooid, stop forming medusa buds, and
