Geneva ? Scientists have discovered at least 52 new species of animals and plants on the southeast Asian island of Borneo since 2005, including a catfish with protruding teeth and suction cups on its belly to help it stick to rocks, WWF International said Tuesday.

“The more we look, the more we find,” said Stuart Chapman, WWF International coordinator for the study of the Heart of Borneo, a 85,000-square-mile rain forest in the center of the island where several of the new species were found. “These discoveries reaffirm Borneo’s position as one of the most important centers of biodiversity in the world.”

Much of Borneo, which is shared by Indonesia, Malaysia and the sultanate of Brunei, is covered by one of the world’s last remaining rain forests.

The discoveries bring the total number of species newly identified on the island to more than 400 since 1996, according to WWF, known in North America as the World Wildlife Fund.
