Introducing "Luca Arnone" a subadult Great White Shark at Guadalupe


In our continuing effort to bring the sharks to you while we are all confined to our homes, let me introduce you to Luca Arnone. He is listed as #163 in our photo ID database at Guadalupe Island. We first met him in 2013 and he has been coming back every year since.

A few years ago "Luca" looked a bit rough. He was partially wrapped in a thick rope, which fortunately was being removed by Dr. Mauricio Hoyos, the local researcher at Guadalupe Island. The cut caused by the rope was not too deep and since white sharks have an amazing ability to heal, it did not cause him any permanent harm. When he swam by me last year, his injury was barely noticeable, with just a faint black mark remaining.

"Luca" was a fairly small shark when we first met him, probably just shy of 12', but he didn't seem to mind the bigger sharks and was a frequent visitor to our cages. He has grown quite a bit in the last seven years but hasn't lost his active behavior. He is still as curious as ever and exhibits a fairly dominant behavior, even towards bigger sharks.

Luca was named by one of our divers, who named 2 different sharks, one after his son, Luca and the other after his daughter Milana. Naming a shark is one way our divers support the ongoing research at Guadalupe Island. The Marine Science Conservation Institute, "MCSI" who maintains the photo ID has various levels of sponsorship available, including naming a shark.

Another way you can support "MCSI" is by coming on one of our "science" trips. A portion of these expeditions goes to fund the research and Nicole Lucas-Nasby, the researcher maintaining that database is coming along as the host. She is sharing the results of her research with you and if we encounter a new shark, you'll also have an opportunity to name that shark. How cool would it be, if you see a shark that you named on "Sharkweek"?

In the video below you'll see "Luca Arnone" with Alyssa and Tristan who named Crazy "Tryss" who we introduced you to earlier here

Our divers can also support the research by letting "MCSI" use their pictures to update the Photo ID database.

If you want to find out for yourself what it's like to come face to face with a great white shark once this virus crisis is over and maybe name one of these sharks, come join us on one of our expeditions. We do have some spaces open and would love to introduce you to our sharks.
