Sharks (The Discovery Channel CD-ROM, CD-ROM for PC/Windows and Mac, $49.95) The Discovery Channel’s line of interactive discs — of which Sharks is the fourth title — are very much like coffee-table books unstuck in time. This one packs in undersea film footage and video interviews with shark researchers to pep up the informative text. Courageous and/or suicidal shutterbugs will find the tips on shark photography especially helpful, but a superfluous Concentration-like game is a waste of disc space. Impressively, the overall message is sharply preservationist — even Jaws author Peter Benchley remarks that he’d make his Great White the good guy if he had to do it all over again. B+
