For 50 years an Israeli oil company kept bathers and scuba divers away from a prime strip of beach in the Red Sea resort of Eilat. But it couldn’t stop the sea life.
In the future, climate change and diminishing nutrient loads may reduce the amount of animals living on the seafloor in the Baltic Sea. This benthic fauna has so far been increasing in shallow waters during past eutrophication, and this has more than compensated for the hypoxia-driven loss of fa ...
A newborn calf spotted among a population of critically endangered killer whales will survive into maturity, scientists say. Researchers are hoping that the juvenile whale is a female, as this will give the group the best chance of producing more offspring.
The world's giant kelp forests—vital marine wildernesses as important to Earth's ecology as rainforests and coral reefs—are being mapped by a team of international scientists.
Gorgonians are an order of soft corals that belong to the large group of Cnidaria, which also includes hard corals, sea anemones, jellyfish and many other species. Gorgonians colonize the seabed all over the world, from shallow coastal areas to deep sea canyons, temperate and tropical areas to p ...
North China's Inner Mongolia Autonomous Region said three major lakes in the region have seen improved ecological environment and increased biodiversity in recent years.
Research finds marine predators are significantly smaller and much rarer in areas closer to people
A researcher studying whales and dolphins was treated to an extremely rare sight in January: a baby humpback whale swimming with its mum, less than 20 minutes after being born.
The great white shark is often viewed as the most hardcore thing in the ocean. The top of the food chain. The silent slayer in the dark. But evidence is increasingly emerging that even the great white isn't safe. In fact, these fish too are prey.
From the ship’s deck, there nothing to see but deep blue water, not the remotest sign of a marine paradise that lies just a few metres below the waves.
The Covid-19 pandemic brought into sharp focus the relationship people around the world have with the ocean. As lockdowns eased, people flocked to the seashore and the beaches as the oceans’ appeal to the inner stirrings of both body and soul became more pronounced.
WWF-Pakistan on Thursday appealed to the government to declare Churna Island a Marine Protected Area (MPA) after coral bleaching was reported in some areas of the island.
One hot 2019 afternoon in Lakshadweep, as marine mammal scientist Divya Panicker sat engrossed in listening to recordings retrieved from underwater sound recorders, she came across low blue-whale moans amid the cacophony of a rooster crow.
Sierra Leone — As dawn breaks, the fishing wharf at Tamba Kula in Freetown buzzes with the movement of early-morning commerce. Fishers just back from days spent far out at sea unload their catch from wooden boats, hauling snapper, barracuda and other fish out of icy compartments into cartons car ...
SUNGAI NIBUNG, Indonesia — The phone signal comes and goes and the electricity grid has yet to reach this patch of jungle on the west coast of Borneo.
