Explore the mysterious sharks that live in the crater

Scientists use specially built underwater robots to study extremely rare sharks that live in volcanic craters on the sea floor, one of the harshest environments on Earth.

The mysterious shark was discovered by chance in 2015 at the Kavachi volcano in the remote area of ​​Solomon Islands in the southern Pacific Ocean. Researchers observe volcanic activity to detect deep-sea sharks near the islands. They first encountered an unidentifiable large brown spherical object and later found it to be the Pacific sleeping shark . This is the case in the farthest southern individual ever recorded.

At first, the team was confused by what was discovered because they did not expect any creature other than bacteria to live in such harsh conditions."Scientifically, there are a number of reasons why it is so difficult for organisms to live there except bacteria. The first is a very hot environment and a high acidity. Second, the water is cloudy. No conditions are available. Fish benefits , " National Geographic quoted researcher Brennan Phillips.

The newly discovered predatory shark can be up to 7 meters long. They swim very smoothly with the body almost moving very little, allowing them to catch prey easily.

Recently, the team returned to the Solomon Islands, equipped with a homemade robot team to learn more about sleeping sharks and volcanoes. Because predetermined machines will be destroyed by volcanoes, they have relatively cheap manufacturing costs. Scientists assemble robots from low-cost materials like sewers."We used some of the used PVC sewer pipes found in the lane. You just need to put electrical equipment on it and have an automatic boat right away," Phillips explained.

Scientists were very surprised and pleased to find volcanic materials clinging to robots during eruptions, making the machine very convenient to collect rock samples.

Robots reveal new information about volcanoes, including robots near water circuits that have a sharp drop in pH and temperatures 10 degrees higher than normal. They also discovered volcanoes as a powerful source of greenhouse gases.

The team is planning to conduct more expeditions to the volcano and hopes to be able to label one of the sharks to monitor their behavior.
