Harbour porpoises, what do they eat?

This video is called Harbour porpoise (Phocoena phocoena).

Dutch biologist Mardik Leopold recently investigated what harbour porpoises eat. He found out (translated):

To find out, he studied the stomach contents of 829 porpoises that had washed up between 2005 and 2014 on the Dutch coast.

In the stomachs Leopold found some seventy different prey species. Four types of prey are really important: gobies, cod species, sand eels and herring species. The staple food of young porpoises consists mainly of gobies, says Leopold. “As they get older and bigger they need bigger fish such as whiting and fatter fish such as herring, sprat and sandeel.”

Otter news from the Netherlands

This is an otter video from Poland.

Translated from Alterra Wageningen in the Netherlands:

Friday, November 20th, 2015

The number of otters in the Netherlands has again increased last year, as evidenced by the latest monitoring data, from the winter of 2014/2015, which are now available. However, this does not apply to the spatial distribution, otters have barely expanded into new areas. There is mainly compaction in the areas where the otter already occurred. Unlike in previous years, there was no further loss of genetic variation due to inbreeding.
