Shark Men

The crew begin working with a new science team and set out to tag tiger sharks in the Revillagigedo Islands in the Season 3 opener.

The crew anchor at Socorro, one of the islands of the Revillagigedos Archipelago. They hook a silky shark, a silvertip shark and a tiger shark before serious electrical issues arise, threatening the entire mission.

The crew modify their methods after failing to hook two tiger sharks. As a result, they land a subadult tiger shark.

The crew find consistent success using their technique to catch great whites on tiger sharks. Later, a remotely operated vehicle armed with an underwater camera is introduced, helping the guys hook two tiger sharks.

As the long, gruelling mission starts to wind down, the tally of tagged sharks continues to rise – along with tensions between the team.

Expedition leader Chris Fischer pushes the team to the limit as they seek one more tiger shark and three more silvertips before leaving the area.

The team battles shark-finning poachers as they attempt to tag hammerheads in the waters surrounding the Cocos Islands.

When Todd hooks a giant tiger shark and the divers abandon a scientist in dangerous waters, it leads to a growing divide over safety issues.

The team finally adds hammerheads to their list of tagged sharks, but the relentless pace of work is wearing some of the men down.

In the last days of the expedition, the team tries everything from midnight fishing to swimming with sharks to tag the elusive hammerheads.
