Vienna-Three Blaupunkt mask rays were born in the House of the Sea in Vienna. You can be seen in the mangrove aquarium on the 8th floor. The species has been bred here, and since 2010 the house of the sea has coordinated its Europe -wide breed. This makes a contribution to maintaining the species. Many of the animals born here have already been taught to other European aquariums, it said in a broadcast on Tuesday.
