Another beautiful nudibranch in the Netherlands at Goese Sas: Polycera quadrilineata.
Today I started diving in the Netherlands again after a cold winter. The weather was not very good and the water temperature still only 11 degrees Celcius. However, it was a great dive with a maximum depth of only 3.2 meters. We did see a lot of nudibranchs, including this nice Flabellina Gracilis at Goese Sas, Zeeland (the Netherlands).
