A diver gets his mouth cleaned by a fish in a deadly deep blue hole

Diver Dominik Černý shared footage from just outside a notorious underwater sinkhole showing a small fish cleaning the inside of its mouth. In a post on Reddit, he said, “Beneath me there was [a] a few hundred yards of nothing and several dead divers at the bottom, but look at this little guy cleaning my mouth.”

The blue hole in Egypt’s Red Sea is one of the deadliest places to dive in the world. More than 100 people – potentially as many as 200 – are believed to have perished there over the past two decades, and memorial stones are strewn around its edges.

The video shows Černý with its mouthpiece removed allowing a small bluestreak cleaner wrasse to do its job. “It was just for fun,” he said Newsweek. “These little fish are known for their passion for cleaning other animals, they even do it to fish like moray eels and other predators. They are quite fearless.

“It was just a slight pinch. It’s a little uncomfortable when it gets to your ear.”

According to the German site The Spiegel, the Blue Hole is about 260 feet in diameter. Its walls are funnel-shaped, with an opening at a depth of about 170 feet. At this point, an archway opens into a sloping tunnel that leads out to sea.

Why so many divers die there is unclear. “There aren’t even any strong currents, quite the opposite. The reason there are so many fatalities is simply because some divers go deeper than they should and that involves huge risks,” Černý said.

In 2017, the Blue Hole and its risks came to light after Irish diver Stephen Keenan drowned at the site. According to Guardian, he was overseeing an attempt by freediver Alessia Zecchini to cross the arch in a single breath. She got in trouble and he went to her aid. While she went out, he didn’t.

“From what I know, people mostly die by drowning,” Černý said. ‘t have proper training for. “

He said that at the depth of the arch, divers can get confused and stop being careful. This can cause them to gasp for air or have seizures.

“From what I’ve heard, [many of] the dead divers weren’t recovered,” Černý said. “The main reason why is the depth.”

The interior of the Blue Hole is approximately 330 feet deep. On the seaward side of the tunnel, the ground drops to approximately 3,300 feet. “Such enormous depths are not accessible to normal divers, and although technical divers can dive 100 meters (330 feet) deep, it is not easy to obtain [the divers] back. It must be a very quiet place there anyway.”

Černý, who has been diving for three years, said being underwater is like being in a different world.

“Everything works there so differently,” he said. “I was amazed when on my first dive I looked up for the first time and realized there was 15 meters of water above me. If you think about it, that’s a lot and I had never realized it before.

“Even though it’s considered an ‘extreme sport’, I’ve hardly ever been so relaxed as when I’m diving.”
