At one time ocean life was uniformly distributed worldwide along the Equator, but the movements of continents and the rise and fall of sea level ensured that many more species survived in the Indo/Pacific basin.
Probably the most important event was the great ice age that covered North America and Europe with two-mile-thick glaciers as late as 18,000 years ago. As worldwide sea levels dropped some 425 feet, many species died out in the shallower Caribbean than in the deeper Indo/Pacific.

Dive the Best of the Bahamas with Us – the Bimini Chain!
I’ve dived on the Great Barrier Reef and in the Galapagos but, in terms of photography, anyway, my 2010 visit to the Atlantis Resort on the southern Philippines island of Negros was my best Pacific experience.
