Fish Use Stones as Tools

A rare occurrence in the underwater successfully photographed a marine biologist Scott Gardner. Gardner accidentally saw a green fish wrasse, also known as tuskfish, banging his little shells to the rock. The goal is to open the shells and eat the contents. "I am greatly impressed by the quality of the images obtained. The fish was as if no matter no orang'di front and take pictures," says Culum Brown, a marine biologist at Macquarie University, who also co-familiar Gardner, "Anyone who sees this will say adaiah smart fish who do smart things. " The fish of this type of mussel shells banging big rocks around it. Indeed, the stone was not used as a hammer that is swung to break the shells. "But it's obvious the fish had been using what is called a tool," said Brown to Life's Little Mysteries. Brown acknowledges that using the word to describe what the tools do the fish a little excessive. During this term the agreed tools are like the monkeys or apes, which is hit with a stick or break something by swinging stone. "But the fish do not have arms and they do not live in an environment like most animals on land. If you're swinging a stick in the water, there is great resistance from the water, so also when hit by stones. So what do monkeys on the ground does not apply at sea , "said Brown. He added that the use of stone as a base to open the shells as did the fish is superb. This indicates a certain level of intelligence. "Of course the fish using a tool in its own way, holding the shells in its own way, and rammed it into the shells on the part of the pointy rock in its own way," said Brown. "In essence, he uses a tool to get maximum results."*** [LLM | FIRMAN | KORAN TEMPO 3603]
