Several species of sharks, ranging from reef sharks, hammers and broken hammers have made an expected appearance in one of the most active volcanoes in the submarine world. Exactly why sharks inhabit this area remains one of the enduring marine mysteries in the world.
Marine ecologist Michael Heithaus from the International University of Florida, has dedicated his life to answering why roof predators are attracted to volcanoes.
This could allow sharks to swim safely before a volcanic eruption.
This sixth mysterious feeling may allow sharks to hunt and hunt for other volcanic islands.
He said: “It seems as if the sharks in the volcano were accustomed to erupting.
“You would think it was dangerous, but studies have shown us that they can detect hurricanes and cyclones approaching, so they may be able to detect when something bad is going to happen and get out of the way.”;
Professor Heithaus also thinks there is a significant link between sharks and volcanoes.
His studies have led him to the island of Réunion, also home to the active volcano Piton de la Fournaise.
Sharks are so plentiful there, swimming has become illegal in recent years.
Eleven people have died in attacks since 2011, mostly from bull sharks.
Professor Heithaus believes that these sharks benefited from the fact that sediments are washed away by the slope of the volcano.
Cloudy waters make it an ideal hunting spot for top predators.
However, sharks have an overall positive impact on the environment.
A recent study found that sharks are functionally extinct on nearly one in five coral reefs.
Professor Heithaus said extreme habitats ironically provide a safe haven for them.
He said: “The biggest threat to sharks so far is being overweight.
“They are just very caught and this is being driven by the demand for shark fin and meat.
“You’re not going to fish around a volcano and maybe some of the bigger sharks, which are predators, will be less likely to get in there.
“We may not know exactly why they are there, but the fact that we have seen so much in a fairly short window of time suggests that it is an important place for those sharks.
“If it weren’t for a great place to live they probably wouldn’t be there … who doesn’t like a hot tub?”
