larval fish associations: accident or adaptation? Can. J. Fish. aquat. Sci., 40(6):754-762.

Capelin larvae (Mallotus villosus) off eastern New- foundland are known to begin their period of larval drift when onshore winds drive in warm, food-rich, predator-deficient surface water masses. Three other co-occurring species (winter flounder, radiated shanny, seasnails) with a similar spawning mode (demersal eggs deposited in shallow water) have larval drift periods synchronous with the same 'safe-site' water masses. Mechanisms and selective advantages of this timing are discussed. Bedford Inst. of Oceanogr., P.O. Box 1006, Dartmouth, NS B2Y 4A2, Canada. (mjj)

83:6792 Norris, K.S. and Bertel Mohl, 1983. Can odontocetes

debilitate prey with sound? Am. Naturalist. 1220):85-104.

Discussed but not proven is the hypothesis that some odontocete cetaceans (toothed whales) may use brief, intense sounds to debilitate prey, thus facil- itating prey capture. Diverse evidence is presented, the special case of the sperm whale is considered, evolutionary and anatomical implications are dis- cussed, and needed experiments and observations are suggested.

field and Michele McLaughlin, 1983. Distri- bution and migration of the bowhead whale, Balaena mysticetus, in the eastern North Amer- ican Arctic. Arctic, 36(1):5-64.

Using records published before 1915, primarily unpublished records from 1915-1974, and reported sightings from 1975-1979, the bowhead distribution and migration patterns were plotted. It appears that the 'severely depleted' population still occupies much of the same area and retains the migratory pattern of the past; however, 'there is no realistic and consistent evidence of appreciable recovery in absolute abundance of any eastern Arctic stock.'

sea: new perspectives. AAAS Selected Sympo- sium, 83. Westview Press, Inc., Boulder, Colo- rado; 210pp. $26.50

Recent research with a Red Sea flatfish (Pardachirus marmoratus) has renewed promise of a truly effective shark repellent; glandular secretions of the Moses sole contain a factor (pardaxin) which affects elasmobranch membranes. Symposium offerings included U.S. Navy shark research, an overview of shark attack and repellency research, behavioral bioassay protocols, behavior modification induced by natural repellents, 3 papers on Moses sole shark repellent effects, 2 papers on pardaxin itself, and the potential for developing shark repellents from ,,)ther naturally-occurring marine substances.

83:6795 Bally, Rod, 1983. Intertidal zonation on sandy

beaches of the west coast of South Africa. Cab Biol. mar., 24(1):85-103.

Study of 3 exposed beaches showed 4 intertidal distribution zones which corresponded to Salvat's (1964) zonation system based on physical parame- ters. Advantages of this system over Dahl's (1952) scheme (3 zones using indicator species) are con- sidered and the observed zonation is compared with that found elsewhere on similar beaches.

1983. Inter-relations of necrophagous amphipods, a fish predator, and tidal currents in the deep sea. Mar. Biol., 74(1):73-78.

Photographic current meter and trap data obtained from the eastern North Atlantic Ocean were used to document the response of abyssal lysianassid am- phipods to large food falls, and predation on these amphipods by Paraliparis bathybius. Paralicella and Orchomene, the most abundant amphipods, occurred in peak numbers during periods of low current velocity. Variation in abundance of Eu.rvthenes gryllus was apparently not related to tidal currents. P. bathybius were present only during flood tides.
