A LTHOUGH I DIDN'T KNOW it when I took the job of curator, my ar-

Cosker had organized an expedition to the Indian Ocean to try and
capture a live coelacanth—the fulfillment, if successful, of Earl Her-
ald's dream. And of course, I would be going along.
The legendary coelacanth, known as a living fossil, has intrigued bi-
ologists the world over. The entire group, many examples of which ex-
ist in the fossil record, was believed to have died out seventy million
years ago. In 1938, however, a live, five-foot-long coelacanth was caught
o¤ the east coast of South Africa by a trawler. Since then a number of
them have been captured, almost all around the Comoro Islands north
of the island of Madagascar. The Comoros were believed to be the sole
location of the remaining population of coelacanths, but surprisingly,

Indonesia, one of which was even kept alive for a short while.
The living coelacanth is named Latimeria, after Ms. Courtney Lat-
