AbstractOctopuses prey on molluscs by boring through their shell.
Among the regular naticid borings, traces of cephalopod predation
should be found soon on Dutch beaches. Bottom trawling
has declined, and by the effects of global warming
Octopus will find its way back to the North Sea where it lived
before. I describe the distinguishing characters for Octopus
bore holes, give an introduction into this type of behaviour,
present a short history of Dutch octopuses and a prediction of
their future.
