• Six Gill Sharks

Roatan, Honduras

The six-gill shark is one of the largest but least known predatory sharks in the world. Six gill sharks, also known as cow sharks, are rarely seen because they spend most of their lives patrolling depths of 300 to 6000 feet, swimming into shallower waters only at night to feed. Six gill sharks are thought to live to be 80 years old and grow to more than 18 feet and 800 pounds.

Sample Itinerary

Observing one of these gentle giants from the comfort of Idabel is truly an incredible adventure. Your shark expedition begins after sunset and takes you 1500 feet down into darkness where you’ll sit and wait in anticipation. Typically, after a wait of one to three hours, she’ll arrive, lured by the bait attached directly to the sub. Ninety percent of the sharks observed in Roatan are female, a mystery that Captain Karl and the Roatan Institute of Deepsea Exploration are helping to solve.

Roatan lies about 40 miles ( 65 kilometers) off the northern coast of Honduras. The tropical island sits on top of a coral reef and is known as a diver’s paradise. Deep water close to shore allows Idabel to operate from a dock and not a support ship. Typical daytime temperatures in Roatan hover in the mid-80s F and nighttime temperatures are in the upper 60s F.

Day 1: Arrive Roatan. Escorted from airport to Cocolobo Resort. Evening free to explore the island’s West End.

Day 2: Time to relax and explore Roatan before meeting Captain Karl and embarking on a late-night mission in search of Six Gill Sharks. The resort is just steps from Idabel’s dock.

Day 3: Free Day. Time to sleep in and dream of all the amazing creatures you encountered beneath the sea. (Shark Adventure Back-Up Day.)

Day 4: Enjoy a great local activity, arranged by Incredible Adventures.

Day 5: Depart Roatan.

The Sub: Idabel is a one-of-a-kind deep diving submersible, designed and built for her exact location on Roatan, Honduras by American Karl Stanley, an adventurer and deep sea explorer who built his first sub at the age of 15.

Idabel is designed to safely transport three people to a depth of 3000 feet ( 915 meters) below sea level. Her safety features include twin ballast compartments, twin high-pressure air systems, a 350 pound droppable lead weight and fully redundant propulsion systems. She has no rudder, dive planes or other moving parts to jam and is equipped to provide three days of emergency life support.

Features include:

  • 30-inch diameter view-port for her passengers
  • 11 powerful lights, including one positional
  • Nine view-ports for the pilot so he can see in every direction
  • Comfortable bench seating for extended dives
  • Built-in sound system with I-Pod docking

Captain Karl Stanley: American Karl Stanley has designed and built two different deep submersibles which he has piloted in three different countries. He’s logged more than 3000 hours of experience piloting a deep submersible and is a member of the Deep Submersible Pilots Association.

Karl’s dives have ranged in depth from 500 feet to 2660 feet and in duration from a few hours to nearly 17 hours. Very few others have the kind of experience Karl has. Karl and his underwater adventures are the subject of a documentary titled “A View from Below,” produced by Rooftop Pictures (available for purchase on Amazon.com).

Six Gill Shark Research

Captain Stanley has teamed up with Roatan Institute of Deepsea Exploration, a local non-profit organization to help in the tagging of six gill sharks for research purposes. If you are interested in making a financial contribution to the study of six gills in Roatan, please let us know and we’ll put you in touch with the right people. A single satellite tag costs about $3500, so any contribution is appreciated.
