Up and down
The Wadden Sea is a very special sea. It’s a tidal sea, meaning that large parts dry up during low tide. This attracts many unique animals that can deal with those changing circumstances. Because of this it’s important that these dynamics stay intact. There has been the threat of oil/gas drillings in the Wadden Sea and the rising sea levels changing this (causing less sea to become dry at low tide), but fortunately there are also other mechanisms that counter this. The Musselbanks in the front of these picture make the seafloor a bit higher again, which hopefully result in keeping this wonderful habitat like it should be.
