Abstract Only a few records exist of the sponge crab Dromia personata in the North Sea. Most records are in local languages, and have limited availability. On 11 August 2016, D. personata was found by divers in the Eastern Scheldt, a former estuary in the south-western part of the Netherlands. In the months to follow, at least four other individuals were observed by divers at the same and nearby locations. This paper lists these and former records in the North Sea. The distribution pattern, and the possible migration of the sponge crab in relation to environmental conditions such as seawater temperature are discussed, as well as the crab’s use of the non-native sponge Celtodoryx ciocalyptoides.
