STUDIES ON SENSORY BASES OF INVERTEBRATE BEHAVIOR AND COMMUNICATION.
Abstract
Bibliographies on chemoreception and mechanoreception of invertegrates have been accumulated and partly indexed. These contain about 4,000 references. Reviews of these fields, as well indexed bibliographies, are to be published. Simplified and inexpensive methods for maintaining marine invertebrates in captivity were developed. Various containers for sea water were used, with coarse coral sand over sub-sand filters. About 100 species from eight phyla were kept for periods of a few weeks to over two years, feeding directly only frozen brine shrimp. Equipment and methods for testing reactions of these small aquatic organisms to simple contact, moving contact, D.C. pressure, A.C. pressure, liquid-borne sound, solid-borne sound (vibration), D.C. water-streams, and A.C. water-streams were developed. Some pieces of equipment were calibrated fully for quantitative studies. With these, 30 species of marine invertebrates, from four phyla, were studied comparatively. A limited study was also made on reactions of three species of sea anemones and two species of opisthobranch molluscs to noxious stimuli, chiefly burning. Regional sensitivity is marked, and the reactions indicate special behavior patterns related to noxious stimulation. The reactions of three species of web-spinning spiders to air-borne sounds, web vibrations, and air-streams were studied comparatively. The reactions are not the same, and different receptors are involved for vibrations than for the other two.
