Novel deep reef ocean section, the Rariphotic teaming with new fish species denotes that distinctive fish fauna perceived from manned submersible on a southern Caribbean reef system in Curaçao, Smithsonian explorers expounded a new ocean-life zone, the rariphotic, between 130 and 309 meters (about 400 to 1,000 feet) below the surface. The rariphotic transpires just below the prior defined the reef zone, the mesophotic which expands from about 40 to as deep as 150 meters (about 120-450 feet). The task of this new zone as a shelter for insubstantial reef fishes pursuing reassurance from warming surface waters or diminishing coral reefs is still not elucidated properly.
The prior inducement for examining deep-reef ecosystems was the decreasing health of shallow reefs. Many researchers contemplate that if deeper reef areas sometimes known as the coral reef twilight zone might behave as safety for shallow water organisms. As the Smithsonian researchers solicit to answer this question, it dawned upon them that scientists have viewed only the tip of the iceberg when it comes to contemplation of biodiversity of reef fishes.
Carole Baldwin, curator of fishes at the Smithsonian’s National Museum of Natural History, lead author of the study and director of the Smithsonian’s Deep Reef Observation Project (DROP) said that it is believed that 95 percent of habitable space on Earth is in the Ocean. And only little of that space has been explored. That’s comprehensible for areas that are thousands of miles away and deep but tropical deep reefs are just below favored, highly studied shallow reefs – necessarily our own back yards.
