An expert has spoken of the likelihood that tragic teen Cameron Robbins died in a shark attack.
The owner of the website trackingsharks.com, Kevin McMurray, collects information and people's stories on attacks and bites in incidents from all across the world, reports the Daily Mirror.
He took time to study the final moments of Cameron Robbins, 18, who was last seen alive on a high school trip to the Bahamas on May 24, after he jumped off the Blackbeard's Revenge sunset pirate cruise.
Kevin said: "At the beginning of it, it looks like there is a shark or something."
"He's in the water and over to the left you can see it.
"So my analysis, what I think happened is, he got in the water and he was swimming around, the shark, for some reason, or whatever it is - I'm not for sure saying it is a shark, but it looks a lot like a shark - essentially it comes and surfaces and there's a life ring out to his right.
"So he's looking at whatever popped up out of the water, and instead of swimming toward the life ring he turns around at that point. I think all that splashing we see is just him trying to get away from whatever it is."
Since Cameron vanished there has been a lot of debate as to what happened in the water.
Fellow high school graduates on the trip filmed the moment the teen from Louisiana jumped into the dark waters, without a life jacket, reportedly as a dare.
"It's always possible [that sharks could attack]," explained Kevin.
"My guess is that if something like that did occur, maybe a single bite or something like that, more than likely, again you can't say because anything's possible, but exposure would probably be what I think would have occurred and he may have died of that.
"Either he sank or a shark ate his body, that's possible. There are a lot of tiger sharks there, and they'll scavenge.
"They're the ones on Jaws that had the license plate tag in their stomach, so they'll eat anything. It's always possible that he could have been consumed, after the fact."
If Cameron's body was, in fact, consumed by a shark Kevin said "it is possible" there could be remains left.
"But," he said, "recovering it would be nearly impossible. Something like that, you're talking about a massive search area with currents and all that."
Before going on the trip Cameron had graduated just days earlier from the University Lab School in Baton Rouge, and went on the trip with classmates and students from other Baton Rouge schools.
Cameron had only just arrived at the Bahamas hours before going on the boating excursion.
The US Coast Guard searched the area and covered over 325 square miles in their search.
However, Cameron was not found and the search was called off two days later on Friday, May 26.
Having analysed the footage, Kevin said: "After I watched the video a bunch of different times, you can actually see him going underneath the netting [on the ship].
"So a lot of people are actually saying he was attacked by a shark right where you see all the splashes, but I think that's just him kicking, and I think he's getting away from it.
"But I think he's still alive and not attacked by a shark at this point on the video, that we can see. Some of the things you think you would hear is him screaming, yelling for help.
"There is a lot of noise on the boat, but he didn't appear to do any of those things... I don't think anybody will ever be able to tell a hundred per cent what happened, but I really don't see any shark attack or bite on camera."
After Cameron jumped into the water in swimming trunks with no life vest, bystanders can be heard saying: "This kid f*****g jumped off!"
As Cameron began to drift away from the boat, another passenger can be heard saying: "Oh my f*****g god. Oh, shut the f**k up. Oh bye... bye... Oh... s**t!"
One passenger shouts: "Grab the buoy... grab the buoy!"
Kevin says something that stood out for him was the lack of noise coming from Cameron throughout.
He said: "I'm surprised that he wasn't yelling or doing anything like that, that's one of the shocking things that you would think somebody that was overboard that wanted to get up would do."
The area where Cameron went overboard is home to tiger and bull sharks, which are among the more aggressive shark species.
While Royal Bahamas Defence Force Commodore Raymond King called the waters "really shark infested", Kevin explained that the sharks are actually drawn to boats.
"Think about that boat," he said.
"There's flashing lights, there's sound, the vibration, and you'll see a lot of boats, like fishermen especially down in Florida and the Bahamas and stuff, they have an issue with pulling fish in and the sharks just hitting them.
"A lot of times what happens is the sharks have this learned behaviour, when they hear the boat motor it's like 'Hey, let's go along and follow it'.... So it's definitely a common occurrence to have sharks around boats like that.
"Is it shark-infested? I don't know if there's any place that's really shark-infested, you know, they live there."
He continued: "Really, sharks aren't that big of a threat in most cases; they do their thing and they'll leave us alone. If you're fishing, different story because now they're looking to eat.
"If you do get in the water with a shark, keep an eye on the shark. If it attacks you, fight, punch.
"A lot of people say to punch the nose, but what ends up happening is the shark's mouth, if you punch the shark on its nose your hand can go right into its mouth.
"So what you do is you go for the eyes and the gills and push down, so that you push the shark away - down and away."
