There are a total of four dolphinariums in the Canary Islands that hold seven orcas and 30 bottlenose dolphins. The most famous dolphinarium is located in Loro Parque, Tenerife, which attracts an estimated one million visitors annually. The Canaries are one of the best places in the world to see whales and dolphins in the sea. The Whale and Dolphin Conservation Organization (WDC) calls on tourists to avoid dolphinariums and instead opt for sustainable whale watching.
The German Maritime Museum Stralsund commemorates the International Museum Day on May 19, 2019 with activities around the topic of diving. The highlight is the demonstration of the replica of a historic diving machine in a dive container at the Ozeaneum.
The most dangerous shark net at the coast of South Africa has been dismantled. For many years, this net was also named "net 99" (in Richards Bay in KwaZulu Natal). The reason it has been installed was that it should protect surfers and swimmers from shark attacks. In the last decad, 15 endangered humpback dolphins died in this network. At the same time, "net 99" only warded off a single potentially dangerous shark. Now the net has been replaced by four baited hooks (drumlines).
The protection status of the inner Baltic Sea porpoises has recently not been included in the list of migratory species at the highest level in Annex I to the Convention on the conservation of migratory species (CMS); despite a request by the Whale and Dolphin Conservation Society (WDC) and the Coalition Clean Baltic (CCB). The reason is that the Baltic porpoise is not a separate species and thus the German Federal Ministry of Food and Agriculture (BMEL) does not consider it to be particularly worthy of protection.
Scientists have looked into the depths of the Great Barrier Reef and documented that they are full of life. They call for taking their findings into account and to better protect the reef. The research team has studied 48 sites at depths between 54 and 260 meters in the central Great Barrier Reef with a sonar and relatively simple BRUVS that attract and film fish with lures.
The research team of Five Deeps Expedition has dived for the first time with a submarine to the deepest point of the Indian Ocean: the bottom of the Java Trench at 7,192 meters. There, the researchers made an amazing discovery that they captured in a video.
Researchers from the University of Exeter and the Plymouth Marine Laboratory, supported by Greenpeace Research Laboratories, studied 50 dead animals from 10 species of dolphins, seals and whales. In all animals they found micro-plastics (smaller than 5 mm). The researchers have now published their findings in a study in the journal Nature.
When it comes to understanding the future climate, the South Asian summer monsoon offers a paradox: most climate models predict that monsoon rains and wind will intensify with increasing human warming - but the weather data gathered in the region shows that rainfall has been decreasing in the past 50 years.

White sharks are still a mystery to scientists. For example, earlier research indicated that the predators prefer open water and rarely dare to swim in kelp forests. New research shows that some sharks in South Africa spend a lot of time in kelp forests, where they may be looking for seals.
