A group of researchers from the University of Sam Ratulangi
Indonesia Institute of Science and Aquamarine Fukushima Japan regained its prehistoric fish called the coelacanth. The fish was estimated to have existed 380 million years ago.
Fish were found in the first day of the investigators on Monday (14 / 9) using the ROV (remotely operated vehicle). The fish was found in the waters of Talise, North Minahasa, in the depths of 155 meters. "This discovery is very surprising. Fish was found alive and swimming freely habitat, "says Prof. Alex Masengi, Dean of the Faculty of Fisheries and Marine Sam Ratulangi University. On 27 June 2007, the same team found a coelacanth fish in the waters Malalayang, the bay of Manado, North Sulawesi at a depth of 190 meters. The second discovery is about 120 kilometers north of the previous one.
Coelacanth fish habitat to be around a depth of 180 meters with a maximum temperature of 18 degrees Celsius in mountain basins of the sea. These fish live only in waters
South Africa and the western waters of eastern Indonesia each
respectively called Latimeria chalumnae and Latimeria menadoensis. New species found in Manado in 1999 shocked the world because since 1940 the coelacanth species known only from the western part of Madagascar. Coelacanth prehistoric fish and categorized as living fossils because it allegedly has existed since the Devonian era, about 380 million years ago.
