The One Ocean Summit opens this Wednesday in the French port of Brest. Seas and oceans cover around 70 percent of the surface of our planet, but continue to face an onslaught of problems, from pollution to rising temperatures. In the Maldives, coral reefs are dying because of climate change. However, locals are doing their best to save them. Our France 2 colleagues report, with FRANCE 24’s Wassim Cornet.
Maldives, officially the Republic of Maldives, is an archipelagic country in the Indian subcontinent of Asia, situated in the Indian Ocean. It lies southwest of Sri Lanka and India, about 750 kilometres from the Asian continent’s mainland.
The deep sea is rife with competition and conflict. Deep sea biodiversity relies on the scattered organisms interacting in order to survive, whether they’re working together in symbiosis, scavenging, being predated, or parasitising a host animal. But there is one ecological interaction that does more than any other to influence organisms to change and diversify, and thus plays an important role in the success of deep sea communities. The limited resources mean only a small number of niches can exist. Thus, there is greater competition between different species trying to fill the same niches. This explains why the deep sea has so much competition, for animals must share the ecosystem with other competing species all trying to consume the same limited resources.

In the second episode of SeaLegacy: The Voyage, Sony Artisans of Imagery Paul Nicklen and Cristina Mittermeier, along with the rest of the SeaLegacy crew, discover sometimes things don’t always go to plan. See how the crew manages the challenge and creates a new game plan when dealing with a sometimes uncooperative dolphin pod. Learn more: https://alphauniverse.com/stories/in-…
A family of saddleback clownfish have found an excellent home, however, they need a place to lay their eggs.
Amphiprion polymnus, also known as the saddleback clownfish or yellowfin anemonefish, is a black and white species of anemonefish with a distinctive saddle. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone.
The killer whale or orca is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. Killer whales have a diverse diet, although individual populations often specialize in particular types of prey.
The octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda. Around 300 species are recognised, and the order is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.
With its insanely clear waters, lagoons, waterfalls and gigantic jungles Raja Ampat is beyond your imagination. There is an unparalleled richness in wildlife and it’s not a coincidence that this gem is home of three-quarters of all known coral species in the world, but this place could be soon in danger. Over the last few years there’s been a noticeable increase in the amount of trash especially plastic in #RajaAmpat waters – Watch the video until the end to see more.
Every day approximately 8 million pieces of plastic pollution find their way into our oceans. Plastics consistently make up 60 to 90% of all marine debris studied. Today, marine conservation is considered one of the greatest scientific problems on our planet. Ecosystems have changed irreversibly, ocean management is fragmented and oceans are managed independently of the terrestrial (land) environment. Nonetheless, given that 71% of our planet is covered by water, the state of our waterways is now one of our most pressing issues.
