The Indonesian coelacanth (Latimeria menadoensis, Indonesian: raja laut), also called Sulawesi coelacanth,
Discovery
On September 18, 1997, Arnaz and
The fish collected by Erdmann was described in a 1999 issue of Comptes Rendus de l'Académie des sciences Paris by Pouyaud et al. It was given the scientific name Latimeria menadoensis (named after Manado where the specimen was found).[10] The description and its naming were published without the involvement or knowledge of Erdmann, who had been independently conducting research on the specimen at the time.[11] In response to Erdmann's complaints, Pouyaud and two other scientists asserted in a submission to Nature that they had been aware of the new species since 1995, predating the 1997 discovery. However the supplied photographic evidence of the purported earlier specimen, supposedly collected off southwest Java, was recognised as a crude forgery by the editorial team and the claim was never published.[12][13]
The fish is legally protected through the Minister of Forestry Regulation No. 7/1999.[14] However, it continued to be caught by local fishermen; on November 5, 2014, a fisherman found a specimen in his net, the seventh Indonesian coelacanth found in Indonesian waters since 1998.[15] Eight have been caught as of 2018.[16]
Description
Superficially, the Indonesian coelacanth, known locally as raja laut ("king of the sea"), appears to be the same as those found in the Comoros except that the background coloration of the skin is brownish-gray rather than bluish. It has the same white mottling pattern as the Comorian coelacanth, but with flecks over the dorsal surface of its body and fins that appear golden due to the reflection of light.[9] It may grow to 1.4 meters long.[17][16]
An analysis of a specimen recovered from Waigeo, West Papua in eastern Indonesia indicates that there may be another lineage of the Indonesian coelacanth, and the two lineages may have diverged 13 million years ago. Whether this new lineage represents a subspecies or a new species has yet to be determined.[21]
