This closeup shows a satellite tag attached to the dorsal fin of an oceanic whitetip shark. The shark was caught, tagged, and released alive during a research cruise near Clipperton Island in 2004. Every time the dorsal fin breaks the surface, the satellite tag transmits data to a satellite, and then to researchers' computers who can track the shark's movements.
