1 - SHARKS

This shark, an adult male, featured in a recent documentary on white sharks which was broadcasted on the National Geographic Channel (could have been Discovery). The sharks were caught with a line in a small boat (dinghy), exhausted (by using buoys), 'guided' towards a research ship and, with an elevator, lifted out of the water. Before they were released, a transmitter was put in the dorsal fin (see photograph). The transmitter transferred a signal every time the dorsal fin broke the surface. In this way, they were able to follow the shark for a considerable amount of time. 

I read an article recently. Most white sharks west of California move between California and Hawai, so it seems. It could be they meet there to mate, but they were not sure.

This is the shark on the elevator just before he was released. At 17 feet and 9 inches, he was the longest they measured:
