Living Fossil EATs Junk Food!
On the 24th of May, 2012, an Indonesian/Japanese team of researchers reprotedly "felt very sad" when they discovered plastic garbage in a coelacanth specimen’s stomach. The specimen had been caught, July, 2011, in Indonesian waters. The fish showed a preference for Lay's Classic Potato Chips! The news was aired by the Manado Tribune on May 29, 2012.

Masa Iwata (Fukushima Acquarium) was in Indonesia again after a break due to the horrible Fukushima earthquake and tsunami from last year. The ROV expedition started early May. In the first period (2nd - May 13th) he succeeded in filming 2 coelacanths in their natural habitat. The region was the same as where the juvenile coelacanth was found on the 6th October 2009.

Triton Dive Charters found several coelacanths during their Sodwana Coelacanth Expedition, March 2012. Coelacanths were found on 3 occasions (5 mixed gas dives were undertaken). On March 6, Peter Timm and his team encountered ‘Noah’, the 14th coelacanth, in Jesser canyon. Later, more coelacanths were seen and filmed/photographed. (Courtesy: Rik Nulens) During these dives, Eve Marshall, became the first woman to dive deeper than 100 m, using SCUBA, to see this special fish in its natural environment. (Courtesy Kerry Sink) Editor's note: Deep mixed gas diving is extremely dangerous, with long decompression times, and has involved multiple fatalities and near fatalities in search of the coelacanth. Don't try this at home! -JH
National Geographic Channel ran a program centered on the Sodwana coelacanths, "Preserving the Specimen." For background on the Sodwana coelacanths click here.
Remembering the hooked, the trawled, and the netted!

Japanese scientists claim Tanga coelacanths genetically distinct from Comoran cousins
( Nov. 10, 2011 ) Researchers from the Tokyo Institute of Technology and other entities said the newly found breeding group of Tanga coelacanths linked to the site, has existed for more than 200,000 years without genetic contact with other groups.
The team published the results in an online edition of the Proceedings of the National Academy of Sciences of the United States.
Tokyo Institute of Technology Prof. Norihiro Okada and his colleagues analyzed genes of more than 20 coelacanths caught off Tanga, northern Tanzania, and nearby sites. The areas are nearly 1,000 kilometers north-northwest of the Comoros Islands.
The results showed the fish belong to a population genetically distinct from that off Comoros Islands.
The two groups seem to have separated 200,000 to 2 million years ago, the researchers said.
Considering the number of fish caught, the researchers assume the newly discovered population may comprise hundreds of coelacanths near the site.
This finding conflicts with the claims of German scientists that the Sodwana, South African coelacanths are genetically the same as the Comoran species. (See articles linked from the Recent History page of dinofish.com)
Another Coelacanth caught in Indonesia.
Capture Date: 21 July 2011. 17:00h.
Capture Place: Tatapaan, Amurang – Minahasa, Sulawesi Utara, Indonesia.
Fisherman’s name: Oktavianus Cowan Kawalo
Condition on capture: alive, dying 1.5 hrs later on the boat.
Method of preservation: Frozen.
Condition after capture: Good.
First ref. cited: Tribun Manado, 22 July 2011.
Current Holding: South Minahasa Fishery Office
Additional comments: Pictures taken. Descriptive name Indo 6. The fisherman went to the Tumpaan fish market where the specimen was recognized by Jefri Lamia as the protected Latimeria. Then the authorities from DKP (Department of Marine and Fisheries of North Sulawesi province) were informed and Mr. Arifin Kiay Demak came immediately to the Tumpaan fish market and took the coelacanth with him to freeze it.

On March 11, 2011, Japan's Fukushima Aquarium was damaged by the tsunami following a massive earthquake. Initial reports indicated that the staff was successfully evacuated to the third floor, but when power to the life support systems was cut off, as many as 200,000 resident aquarium fishes died. Some marine mammals were removed to other facilities. The impact of this event on the aquarium's coelacanth search program is presently unknown to dinofish.com, however the aquarium is scheduled to reopen this July 15th.
During the November 2010 expedition, scientists from Fukushima Aquarium in Japan, in cooperation with the Sam Ratulangi University in Manado (Indonesia) were able to locate and film 5 coelacanths (in three dives) in Indonesia. With the ROV they traced these coelacanths close to Biak Island (Papua/Indonesia), about 1800km more East than the previous dive locations around Manado (North-Sulawesi).
Later, three more were observed in the same area. (photo below)
Here are the results from the ROV investigations around Biak.
For the statistics…
11 November between 14:22 and 14:46 at a depth of 210m – 2 Coelacanths
13 November between 16:48 and 17:05 at a depth of 194.93m – 3 Coelacanths
15 November at 14:54 at a depth of 194.91m – 1 Coelacanth
One coelacanth has been seen twice, so in total 5 different ones.
On September 21, 2010 a pregnant female coelacanth was caught North of Karanga Island, about 750 m from Nyuli sand bank, heading east, in Tanzania. The female had about 17-19 pups in her belly and has been preserved.
On 21/22 September 2010 and on 27 November 2010, two coelacanths were found in a shark net in Madagascar, West of Nosy Ve (Anakao) – Toliara in Madagascar. Both specimens are now preserved. Sad news came from Zanzibar a few days ago where the female coelacanth and her 23 pups, caught on 17 July 2009, had to be discarded because they had decomposed, due to problems in the electricity distribution on Zanzibar.

First Filming of Living Juvenile Coelacanth
The sixth R.O.V. expedition of Japan's Aquamarine Fukushima, succeeded in locating and filming a juvenile coelacanth on October 6th, 2009. The fish was found in Manado Bay, North Sulawesi, Indonesia. It was measured by a laser beam to be 31.5cm. The expedition leader was Masa Iwata from Fukushima Aquarium. (Courtesy Rik Nulens).

The same expedition that filmed the juvenile made a picture of six coelacanths in one cave. See the full account of the Fukushima expeditions on dnofish.com at Recent History/Fukushima. , and an account of the Indonesian Coelacanths at Recent History/Indonesian Coelacanths.
New Coelacanth Research Center / Shrine
One small step for a fish! The Coelacanth Rescue Mission (CRM), funded by contributors to this web site via Coelashop purchases, initiated financing for a coelacanth research center (CoelaCenter) at Itsoundzou, a fishing village on Grand Comoro island in the Indian Ocean. The center is within several hundred feet of where the largest and most studied colony of coelacanths reside by day in their submarine caves. It is being built and will be operated by APG, a local group supporting coelacanth conservation. The center will be used to increase conservation awareness locally, and conduct ecological research. It will also be a museum dedicated to the history of the coelacanth. Groundbreaking began in April '04. By winter '08, thanks entirely to "coelashoppers" walls were completed for the first floor. In Feb. '08, the Comoros office of the United Nations Development Project (UNDP) Global Environment Facility/ Small Grants Programme, agreed to finance the next phase of the Center's completion, an exciting giant leap for the center and the people of Itsoundzou..
