They call it the last sanctuary of sharks. It is also known as the Eastern Tropical Pacific, home to a rich diversity of marine life. It's the underwater equivalent of the Serengeti, with vast migrations of wildlife seasonally traversing the expanse. Many shark species, including our two target species - tiger sharks and hammerheads - thrive here.

The Expedition Great White team sets off on three expeditions to this spectacular region with some of the area's most experienced researchers. "Dr. Hammerhead" Peter Klimley and some of his post docs form the core of our investigative team. With mother ship OCEAN and her experienced crew, we set forth to answer some big questions about big predators. Insight and adventure ahead!

EXPEDITIONS: Three expedition destinations within the Eastern Tropical Pacific have been chosen: The Revillagigedos, Cocos Island, and The Galapagos. They mark three key positions along the shark superhighways of these seas. How they each figure into the great migrations and are connected is fundamental to this research.


  • Shark Men 3: Tagging Tigers
    It is the same crew but everything else has changed; fresh science team, new shark species, varying landing methods, and in unfamiliar territory, the Revillagigedo Islands. Chris' team and Dr. Hammerhead (Pete Klimley) will work together to try to help the scientific community learn about tiger sharks, Galapagos sharks, and many other shark species. The biggest hurdle this team will have to overcome is finding a balance between the differing opinions on how to land the sharks.
  • Shark Men 3: Hammerhead Islands
    The Shark Men anchor at Socorro, one of the four islands that make up the Revillagigedo Archipelago. The hunt for hammerheads continues and with the help of the Shark Men Dr. Pete Klimley hopes to uncover the mysteries of shark migratory behavior in this region. The question was to use the sling the scientists would prefer or use the trusted lift that the crew has used time and time again. But now there is a bigger question: will either of them work? The MV Ocean has been temperamental ever since they left port, but will she breakdown when they need her the most?
  • Shark Men 3: Tiger Escape
    The Shark Men are challenged as never before. They hook three sharks including two giant tigers. But they get away. Even for these pros, the sheer power of the tiger sharks catches them off guard. Determined, they redesign their approach and start using the kind of tackle they use to land giant great whites. It pays off big time as a subadult tiger shark they name Sara Beara, is successfully tagged and sent on her way.
  • Shark Men 3: Tiger Bait
    After a long stretch of nothing but frustration, the team is finally seeing consistent successmostly due to the realization that the technique used to catch great whites works perfectly on tiger sharks. Chris Fischer, the expedition leader, finally unveils the remote operating vehicle with an underwater camera that he says is crucial to effectively finding and landing their targetsand it works, helping them hook two tiger sharks. Even though theyre all exhausted, the scientists and crew are now determined to catch and tag five sharks from five different speciesbecause they know that the tagging operations are part of an urgent mission to help protect and understand these magnificent fish.
  • Shark Men 3: Coming Unglued
    At the Revillagigedo Islands off Mexicos western coast, the tally for tagged sharks is rising but so are tensions among the men. As the long and grueling expedition winds down, the Shark Men struggle to put personal conflicts aside to stay focused on their ambitious and urgent mission to save as many shark species as they can.
  • Shark Men 3: A Whale of A Tiger
    The men are tired, tense and determined to succeed but the window is fast closing. One more tiger shark and 3 more silvertips are desperately sought before they need to pull anchor and leave the region. Expedition leader Chris Fischer keeps pushing the men to focus and keep working until the very last second.
  • Shark Men 3: Trouble In Paradise
    APPROVED Under the cloak of darkness, shark finning poachers boldly enter Cocos Islands protective waters and this is the first time the Shark Men have on-board security in case theres a confrontation. Under tense conditions, the teams main species for tagging are hammerhead sharks. Because of their bigger fins, they are a highly sought after species for slaughter
  • Shark Men 3: Mission Critical
    The Shark Men divide and conquer to get the job done, but that approach causes some safety issues. While divers scout for hammerheads, Todd is off by himself and hooks a giant tiger shark. The divers support boats rush over to assist Todd leaving the lead scientist alone in dangerous waters The tense episode is the start of a growing divide between the anglers and scientists on priorities and protocol. But in the end, the mission takes precedent and they wind up having their best day ever in terms of tagged sharks. Costa Ricas Cocos Island is a designated protected area and the rangers are keeping a skeptical eye on the men. But their mission is urgent as thousands upon thousands of sharks are illegally finned in these waters.
  • Shark Men 3: Killing Zone
    Though the team finally adds hammerheads to their list of tagged shark species, theres little celebration aboard the mother ship. The relentless pace of work is wearing some of the men down and tensions flare within both the science and angling teams. Lead scientist Pete Klimley and his second in command Alex Hearn, clash in a screaming match that comes close to an all out fist fight. Pete also goes viral on Expedition Leader Chris and Captain Brett setting an anxious undertone throughout the crew. At the end of the day, the mission to protect the sharks rises above all else although personality conflicts continue to simmer.
  • Shark Men 3: Hammered
    It is the same crew but everything else has changed; fresh science team, new shark species, varying landing methods, and in unfamiliar territory, the Revillagigedos Islands. Now working with Dr. Hammerhead (Pete Klimley), Chris and the doctor will work together to try to help the scientific community learn not only about great whites but tiger sharks, Galapagos sharks, and many others. The biggest hurdle this team will have to over come is finding a balance with the differing opinions on landing the sharks. Now with the Explorers Club flag flying over their heads these two teams will try to become a family and stay together for the sharks.
