Rather than harpoon the sharks from a distance, the Ocearch team baits the fish and leads them onto a lift.
They tag and take blood and tissue samples up close.
The real-time satellite tag tracks the shark each time its dorsal fin breaks the surface, plotting its location on a map.
The crew caught their first shark September 13 and named her genie for renowned researcher Eugenie Clark.
Genie has already traveled about 50 miles.
