Wageningen/Stuttgart, 13.04.2023. It is five centimetres long, but larger than all its relatives: Microichthys grandis, literally ‚big little fish‘. Researchers from the State Museum of Natural History Stuttgart in Germany and Wageningen Marine Research in the Netherlands discovered this new fish species during a survey off the Irish coast last year. This finding in the Northeast Atlantic is something special for the scientists and has now been published in the scientific journal „Ichthyological Research“.
