The three otters were lying together on the road and, according to Arend Spijker, are ‘one hundred percent traffic casualties’. Spijker, a member of the Otterwerkgroep in Overijssel and former forester, received a report early this morning of the dead animals. He has already collected them. They later go to Wageningen University for DNA research. “We always do that with otters who are traffic victims. This way we can learn more about them. Where they come from, what their living environment is and whether they are related in this case, for example.”
