NATIONAL OCEANOGRAPHIC PROGRAM—1965 
ECOLOGY OF MARINE ANIMALS 
Types of environment in the ocean, with special reference to 
shallow tropical seas; the relation of distributions to the 
physical and chemical environment; effects of environmental 
changes; breeding cycles; plankton and food chains, causes 
of population fluctuations. Application of ecological tech- 
niques to local problems. 
INVERTEBRATE EMBRYOLOGY 
Early development of invertebrates including the proto- 
chordates, life histories, larval stages, and metamorphoses 
of the principal types and their evolutionary significance; 
larval adaptation, methods and techniques. 
BEHAVIOR OF MARINE ORGANISMS 
Sensory physiology; acuity and sensitivity of marine organisms, 
and their sensory adaptation to various marine environments. 
Sound production and its significance in communication; social 
behavior; predator-prey relationships. Field trips will stress 
comparative behavior of local species. 
PLANKTON 
The drifting organisms, the influence of environment factors 
upon them, their place in the conomy of the sea and fresh- 
water habitats, and their relation to fisheries. 
PHYSIOLOGY OF MARINE ORGANISMS 
Osmotic regulation, behavior, feeding, metabolism, nerve and 
muscle function, endocrines, blood chemistry, excretion. 
671,672,673,674,675. ADVANCED STUDY IN MARINE BIOLOGY 
Supervised reading and study in areas of special interest to 
advanced students. 
681,682. MARINE BIOLOGICAL RESEARCH 
686. 
Advanced research. 
BIOLOGY OF MARINE FISHES 
Special emphasis on tropical species. Field work devoted to 
individual research in food habits, development, growth, be- 
havior, physical and chemical tolerances, parasites, and 
physiology of local fishes.
