Sven Erik Gehrmann, born in 1969, was originally born in Berlin. Since 2011, he has been living on the North Sea coast of Lower Saxony, where he maintains numerous relationships with fishermen, marine biologists, journalists, employees of public institutions and other people who are concerned with the topic of the sea and its diverse inhabitants. He runs various small and large aquaria to study and document the behaviour of marine animals. His particular passion are the inhabitants of the North Sea and the Mediterranean. That is why he keeps and maintains various collections. He has always been fascinated by groyne, beach and silt fringe finds. He would like to share his observations and insights with others in order to make a small contribution to a new environmental awareness.
