Fast Enough. How fast is a snail's pace? At College Park, Md., U.S. Fish & Wildlife Service conchologists (mollusk fanciers) were measuring to find out. Dr. Paul Galtsoff puts a seagoing snail inside a drum of transparent plastic. When the snail moves (either forward or backward) the drum revolves, recording the snail's motion on a sheet of smoked paper. Conchs move fastest: an average 19 feet an hour. Little oyster drills, one inch long, move only a couple of feet...
...Galtsoff has a practical objective: protecting U.S. oyster beds from snails, which eat about $6,000,000 worth of oysters each year. The drills gnaw a hole in the oyster shell with a filelike organ called a "radula"; then they insert the toothed front end of their stomach and nibble the oyster away. Conchs do their dirty work on the edge of oyster shells. When all the oysters have been eaten, they file holes in one another...
...tentative diagnosis, from Fish & Wildlife's Dr. Paul S. Galtsoff: Florida's affliction, though rare and annoying, was nothing new. In various parts of the world, sea water is occasionally poisoned by "very rapid reproduction of unicellular organisms of the group of Dinoflagellates." California, Florida was happy to learn, has had the same trouble. Japan's pearl oysters have also suffered from the destructive Dinoflagellates...
