Star material: Intelligent and en-
dowed with keen memories, California
sea lions often appear in circuses--
under the stage name of "seals."
Training a sea lion to balance a ball
on its nose may take a year, but a
star can then perform perfectly for a
decade or more. Sea lions also work
as divers for the U.S. Navy. They can
retrieve a sunken object more safely
--and cheaply--than can human divers.
