Estuaries and swamps have been looked upon by some writers (Hesse, 1920; Annandale, 1922) as refuges where primitive and archaic types may persist after they have been driven from the ocean. Examples of animals cited as those which have thus persisted in fresh water are hydras, certain crabs, and ganoid fishes. There are marine animals which fear the sea. For example, the fiddler and macrophthalmid crabs which live in the intertidal zone.
