Well last year, scientists at a lab in Hungary had a real OOPS moment. At the Research Institute for Fisheries and Aquaculture, they just wanted to try to preserve critically endangered species. Their focus was the Russian sturgeon, also known as the diamond sturgeon. Instead of merely fertilizing the eggs and then disappearing into the ether, the sperm actually fused with the eggs, creating a hybrid fish, affectionately known as a “sturddlefish.”Research Institute for Fisheries and Aquaculture in Hungary reported to have created hybrid fish of Russian sturgeons and American paddlefish. This new, uninentional hybrid species had some interesting differences.
