Background: The rising temperature of the world’s oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin. Methodology/Principal Findings: Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers’ field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality exceeded prior efforts in detail and extent, and provided a new standard for documenting the effects of bleaching and for testing nowcast and forecast products. Collaborators from 22 countries undertook the most comprehensive documentation of basin-scale bleaching to date and found that over 80% of corals bleached and over 40% died at many sites. The most severe bleaching coincided with waters nearest a western Atlantic warm pool that was centered off the northern end of the Lesser Antilles. Conclusions/Significance: Thermal stress during the 2005 event exceeded any observed from the Caribbean in the prior 20 years, and regionally-averaged temperatures were the warmest in over 150 years. Comparison of satellite data against field surveys demonstrated a significant predictive relationship between accumulated heat stress (measured using NOAA Coral Reef Watch’s Degree Heating Weeks) and bleaching intensity. This severe, widespread bleaching and mortality will undoubtedly have long-term consequences for reef ecosystems and suggests a troubled future for tropical marine ecosystems under a warming climate

Among the fish species of the family Nemipteridae, the two little known species, namely, Nemipterus mesoprion (Bleeker) and Nemipterus delagoae (Smith) are recorded from the Cochin waters. Nemipterus mesoprion is a new distributional record from the west coast of India. N. delagoae is described with adequate numbers of specimen for the first time from Indian waters. Moreover, the results of the present study show that the colour of the viscera, the number of pyloric caeca and the gill rakers can also be used for the diagnosis of the species of the genus Nemipterus. The affinity of the above species with other related species of the genus Nemipterus and their geographical distribution are presented.

A description of a whale shark (Rhincodon typus) captured on June 1934 along the coast of Cap Ti Oan is given. The scientific name Rhincodon is not correct due to a typographic error. The name with greek origin, should be: Rhineodon typus.

Many aquarists know this fish as Ambylgobius hectori but accepted name is actually Koumansetta hectori. K. hectori, Hector's goby, is a species of goby native to the Indian Ocean (including the Red Sea), first record from Persian Gulf (Kish Island, Iran) to the islands of Micronesia in the western Pacific Ocean. It can be found on sheltered coral reefs at depths of from 3 to 30 meters (though usually between 5 to 20 meters). This species reaches a length of 8.5 centimeters (3.3 in) SL. This attractive little fish measures only 2” at maturity and spends its time hovering over rocks and substrates out in the open water column. Known for their bold yellow stripes, peaceful disposition, the diminutive Hector’s Goby is a nano reef favorite. It can also be found in the aquarium trade.
