Some advances in coelacanth biology.

Participants in the British-French-American Expedition to the Comoro Islands in 1972 were able to observe a living coelacanth and to obtain fresh tissue from two specimens, which were processed in the field for subsequent research. This work, by many people in several countries, still continues, and this lecture gives a condensed account of some of the investigations so far published and in progress. Separate accounts of the French contributions, by J. Anthony, of the chemistry of the body fluids, by R. W. Griffith, and of the respiration, by G. M. Hughes, are being published concurrently, the four papers being complementary to each other. A bibliography on Latimeria is included.
