Squids, for example, are attracted to the angler fish’s bright antennae, and are lured to their fate by the beckoning light. They can use it to attract prey (as seen in the anglerfish), to enhance vision for finding prey, for mate attraction, or even to expel bioluminescent fluid in order to escape predators ! For those animals using bioluminescence to attract prey, it is used to attract sighted animals. Marine organisms use bioluminescence for distinct functions. Other marine life, such as jellyfish, sea squirts and squid, also illuminate. Among marine vertebrates, bioluminescence is observed in cartilaginous fish no lobe fish have been reported to have this trait. However, bioluminescence is most common amongst aquatic life. Fireflies are an example of bioluminescence on land. īioluminescence is seen all over the world, not just in the oceans. These species, for example, vary in whether they have bioluminescent lures. Not all deep sea anglerfish were created equal. Of these 321 species, about half live in the deep sea. These fish are in the order Lophiiformes, which consists of 321 species. Anglerfish obtained their name from using their lures in a way similar to how fly fishermen use their imitation flies. In The Blue Planet, a deep sea angler fish swims rapidly with its angler waving back and forth in constant motion. Anglerfish use bioluminescence to attract prey in the deep ocean. The International Union for Conservation of Nature has documented damage to them from marine heatwaves in recent years.Anglerfish shine a light in perpetual darkness, but beware: Not all lights lead to safety. Kelp are threatened by human-caused climate change, which warms the oceans. They found the kelp-whose support of numerous lifeforms was noted by Charles Darwin-sequester 4.91 million metric tons of CO 2, thus removing planet-warming gas from the atmosphere. “Globally, these kelp forests produce an estimated average $500 billion per year,” they concluded, making them “over three times more valuable than previously acknowledged”. They also calculated the benefits from kelp’s role in nitrogen and CO 2 removal. The international team of scientists quantified the contribution of six kinds of kelp to fisheries production through the species they support. The study published in Nature Communications offered a rare gauge of the contribution from the tall seaweed, which is threatened by climate change, valuing it at three times the amount previously thought. Scientists estimate sea kelp generates $500 bn a year (PHSY.ORG) The other component will establish an inter-ministerial commission and regional coordination mechanisms to facilitate coordination between sectors of the blue economy. The Moroccan government will use the loan to strengthen natural resource management, develop institutional frameworks and improve strategic sectors that will make the country’s blue economy more resilient to climate change. This will include vocational training in blue economy management, training in ecosystem restoration and management and improving climate resilience in coastal areas. According to a news story in Afrik21, a key component of the funding will be invested in sustainable aquaculture and tourism projects to help jumpstart the country’s Covid-19 recovery. The blue economy development programme hopes to stimulate job creation and economic growth, while shoring up food security and improving the sustainability and resilience of Morocco’s natural resources.
