...hatch in shallow streams, releasing larvae, or alevins B, which within a few months become juvenile fish called parr. Parr, in turn, grow into 8-in. smolts C in about two years, and it is these small, silvery fish that make the improbable migration from freshwater river to saltwater ocean. Smolts that survive the trip--and plenty don't--spend four years at sea, feeding and growing to full adult size (3 lbs. to 126 lbs.). Then they begin the long upstream journey D back to their hatching grounds, where they spawn and, a few weeks later, die. A small...
Before Cousteau, undersea exploration was limited by the length of a human breath or the tether on a diving helmet. His co-invention of the Aqua-Lung in 1943 freed us to roam the ocean depths--like an "archangel" flying through the heavens, as he put it.

In his last book, Man, Octopus and Orchid, published shortly after his death in 1997 at the age of 87, Cousteau summed...

Today, the grandchild of that immigrant can return again and again across a vast ocean in just half a turn of the clock.

...years continental drift was held up to derision--until scientists in the 1960s found a plausible mechanism in the earth's internal motions under the ocean floor. Suddenly, Wegener's disreputable ideas became reputable. Renamed plate tectonics, they gave geology a single unifying theory, explaining everything from earthquakes and volcanoes to the formation of mountain ranges and ocean basins. Sadly, Wegener, who perished on the Greenland icecap in 1930 at age 50, didn't live...
