Pipefish, Ecomare


Two species of pipefish are commonly found in the tidal regions and the coastal water: the great pipefish (up to 50 centimeters) and the lesser pipefish (up to 20 centimeters). The great pipefish is more common, mostly found in deep channels of tidal regions. Pipefish live primarily between seaweed and eelgrass, and therefore swim in pools on overgrown sea dikes and breakwaters. They suck up small crustaceans and fish larvae. Pipefish care for their brood: the males carry the eggs and the larvae (in June and July) in their brood-pouch.

    Snake pipefish, Ecomare

    The snake pipefish used to be rare in the North Sea but has been increasing spectacularly in numbers. Sea birds along the English-Scottish rocky coasts even use dried specimen as nest material. One is caught in the Wadden Sea every once in awhile. The deep-snouted or broad-nosed pipefish disappeared from the Wadden Sea together with the eelgrass in the 1930s.
