The USA piece was interesting though with the usual superficalities. "Coelacanth" is actually the name of a group of fishes, not a "species" as suggested in the story. Coelacanths and their other relatives were thought to have become extinct towards the end of the Age of Dinosaurs, but in the 1930's fishernmen caught a specimen off the coast of South Africa. The group to which they belong, the lobe-finned fishes--include ancient forms that gave rise to the earliest amphibians about 370 million years ago. Coelacanths survived because they adapted to deeper marine waters. No one is really certain how common or uncommon these fishes are, but several specimens have been caught and studied. Occurrences have been reported in Asia as well as Africa and more than one species may actually exist. The animal is adapted to deep water and this is likely the reason it does not survive in shallow waters. The term "living fossil" is frequently misused. In this case, the last documented forms were previously reported from rocks older than 65 million years, until the dicovery of living animals in the 1930's and thereafter. Obviously the group did not become extinct during the age of dinosaurs. It is simply that up to no, no fossils have been recovered as yet for the intervening period.
