The mangrove rivulus, also known as the mangrove killifish, is native to the Americas and is about five centimetres (two inches) long.

The fish has long been studied for its many unique features. It's the only vertebrate known to naturally self-fertilize, for example. In some populations, it can become a hermaphrodite, developing both male and female parts simultaneously, to produce clones of itself.

“This discovery gives us great hope that there is a future for Irrawaddy dolphins,” said WCS researcher Brian D. Smith, who led the study. “Bangladesh clearly serves as an important sanctuary for Irrawaddy dolphins, and conservation in this region should be a top priority.”

The scientists counted nearly 6,000 of the dolphins in the South Asian country’s Sundarbans mangrove forest and the adjacent waters of the Bay of Bengal.

As one of the eight new natural sites that have been added to the World Heritage List, following IUCN’s recommendations you find the Socotra Archipelago in Yemen. Socotra is a small archipelago of four islands and islets in the Indian Ocean off the coast of the Horn of Africa some 190 nautical miles (220 mi/350 km) south of the Arabian peninsula. It is a part of the 'Adan Governorate of the Republic of Yemen.

The diving centres on the black list have not complied to standards EN 14467/ISO 24803 for Recreational Diving Services and will not be able to renew their license from the Ministry of Tourism and therefore will be operating illegally.

The auditing process to check that diving centres are meeting these standards began in May 2008 and by 31st March 2009 was completed in South Sinai and will continue to 31st July 2009 in the Hurghada area. Steps will then be put into action to close down illegal operations that fail to comply.
