a Maritime Expeditions Around the Cocos and Christmas Islands, About 2,500 km off the west coast of Australiahe got Rare species inhabiting the depths of the Indian Ocean, scientists found From fish that look like meatballs to others that can “stand up” on their fins,
A group of experts has been working since 30 September First mapping of ocean floor biodiversity CSIRO RV investigator aboard ship, local agency told Australian Broadcasting Corporation (ABC).
The life of the species, which lives in waters about 5,500 km deep, is difficult: there is little light and little food. This is the perfect place to hide. Diane Bray, manager of the research institute at Museum Victoria, who is aboard the ship, said the fish scientists have managed to find in these waters are “terrible and unique”.
“They have to do bioluminescence to create light to attract food, hide or camouflage in the deep ocean,” he said. The researchers found that one of the strange creatures is the so-called “tripod fish,” a species with fins that allow it to rise from the ocean floor.Which will allow him to eat any food that comes his way.
Another special species was found Deep-sea baitfish that resemble dumplings, “They have a small lure that sits in a depression in their snout that they can actually spin to attract prey and essentially walk on the ground with their modified arms and legs,” Brey said. Told.
But there was one creature in particular that caused the biggest surprise among the members of the expedition: the “Blind Clown Fish”, which scientists suspect is a new species. The fish are collected with a net and then graded on the boat. Once they return to shore, the scientists analyze and complete their search.
Mapping a ‘magical underwater world’
Scientists aboard the investigator are currently working on World’s first 3D map of islands, revealing unique underwater mountain ranges. Voyage chief scientist Tim O’Hara said most of the ocean floor was known only from “diffuse spots that had just been detected by satellites”.
,[Nuestro mapeo] It revealed this whole magical underwater world of valleys and ridges and sediments and old volcanoes,” he said, adding, “Now we’re in the south and we’re also mapping the frontiers and each one is completely different.” “
images a. is collected using sonar multiphase, “It pulsates downward and bounces back onto the ship and that allows us to estimate the depth of the ocean floor,” O’Hara explained.
“It also helps people plan fisheries and future management by determining where particular fish congregate at different times of the year. It is really important to understand the landscape as a way of understanding the environment”, said the expert.
