On Saturday, May 19 2007, a fisherman found a King of the Sea, an ancient fish biologically known as Coelacanth latemeria, in his fishing line in Malalayang Beach, North Sulawesi. It was the second fish found in North Sulawesi after the first finding in 1998 in Manado Tua Beach. The coelacanth has 130 cm length, 46 cm width and weighs 50 kg. Yustinus Lahama and his son Delfi Lahama, who found the fish are fishermen from Malalayang.
Yustinus and his son went out fishing for their family consumption. Only 5 minutes after putting his line, he felt it has hit a big thing. He withdrew the line and found a big weird looking fish with white color spots hooked in his bait. Yustinus said "The fish was calm when it was brought on board, but then it moved violently that destroyed things on the boat."

This event has drew attentions from the Governor of North Sulawesi, Drs. Sinyo H. Sarundajang and Ministry of Marine Affairs and Fishery, Mr. Freddy Numberi who was in Manado at that moment. First, they put the coelacanth in Bahu Mall, then they moved it to a safer aquarium in City Extra Kalasey Restaurant.
"It inspired Sarundajang to make this fish as the mascot for World Ocean Conference in Manado in the year 2009," said Angelique Batuna, WWF-Indonesia Project Leader Bunaken Program.

To further observe and preserve the fish, the government will invite an icthyologist (fish expert) and will launch the results in a press conference next week.
The first known about the fabulous Coelacanth ("see-la-kanth"), that 400 million years old "living fossil" fish, swims on. Pre-dating the dinosaurs by millions of years and once thought to have gone extinct with them, 65 million years ago, the Coelacanth with its "missing link" "proto legs" was "discovered" alive and well in 1938. An adult Coelacanth can grow at least to 200 cm in length and weigh 100 kg.

On January 18 1980, Coelacanths are considered to be endangered and are protected by the Convention on International Trade in Endangered Species of Wild Flora and Fauna (CITES). The word of Coelacanth is from Yunnan, coelia: cavity and acanthus: spine, it is a large marine lobe-finned fish. Ika Rachmatika S and friends from Biology Research Centre LIPI tell about different of morphology and genetic character both Coelacanths latimeria chalumnae from Komoro and Coelacanths latimeria menadoensis from Manado.
Different of Latimeria chalumnae (Kepulauan Komoro) and Latimeria menadoensis (Manado) | ||
Kind of difference | Latimeria chalumnae | Latimeria menadoensis |
1. morphology and genetic character | Scale of fish is blue with white pock. | Scale of fish is brown with white pock. |
2. meristic character | It has many back flipper scales and less tail flipper scale. | It has less back flipper scale and many tail flipper scales. |
Numerous characteristics are unique to the coelacanth among living fishes. Among them is the presence of a "rostral organ" in the snout that is part of the electro sensory system, and an intracranial joint or "hinge" in the skull that allows the anterior portion of the cranium to swing upwards, greatly enlarging the gape of the mouth. Neither of these characters exists in any other living vertebrate. Other unique anatomical features include a hollow fluid-filled "notochord" (a primitive feature in vertebrates) underlying the spinal cord and extending the length of the body.
