A French-led marine expedition team believes it has discovered thousands of new species of mollusks and crustaceans around a Philippine island, officials and scientists announced Monday.
Some 80 scientists, technicians, students and volunteers from 19 countries surveyed waters around Panglao island, 390 miles southeast of Manila from 2004-2005.
The Panglao Marine Biodiversity Project turned over to the Philippine National Museum on Monday more than a hundred holotypes or representative specimen of the rare finds, officials said.
"Numerous species were observed and photographed alive, many for the first time, and it is estimated that 150-250 of the crustaceans and 1,500-2,500 of the mollusks are new species," said a statement from the expedition team, which was led by Philippe Bouchet of the French National Museum of Natural History.
"However, it requires a thorough comparison with all previously named species to ascertain if a novel species is indeed new to science," it added. "This is a slow and tedious process."
The expedition team said its survey revealed over 1,200 species of decapod crustaceans — a group that includes crayfish, crabs, lobsters and shrimps — and some 6,000 species of mollusks.
The expedition received funding from the French Ministry of Foreign Affairs and the Total Foundation.
