CHASING WHALES to obtain 

 educational motion pictures is 

 an exciting sport for scientists. 

 Tail flukes of a great killer 

 whale are shown as the mam- 

 mal sounded in San Gabriel 

 Bay, Espiritu Santo Island, in 

 the Gulf of California. Greatest 

 show on earth is killers attack- 

 ing a large whale. 



FAMOUS LIZARD among scientists is Diploglossus hancocki, a rare species dis- 

 covered on Malpelo Island some 200 miles off the coast of Colombia and 300 

 miles westerly from Panama. The island is a sheer rock, on which landings are 

 most difficult. Herpetologists named the species in honor of Captain Hancock 

 who made its discovery possible.
