Sir David Attenborough and chameleons in Madagascar, then and now, a brilliant video that mixes flashbacks from a 1960 television show called Zoo Quest with 2008 color footage shot for the BBC TV series Life in Cold Blood. He has spent six decades presenting programs for the BBC thus far.
There are more wonderful BBC clips, many with Sir Attenborough, in the archives.
In this absolutely incredible footage from EarthTouchTV, watch hundreds of thousands of sardines off the coast of South Africa swarm at the center of an animal feeding frenzy. With Earth-Touch divers right in the middle of the action, large, hungry predators — sharks, dolphins, diving gannets, and a 20 to 30 ton Bryde’s whale — all take part in this intense and fascinating sardine run.
There are hours of nature and underwater videos in the archives.
