Orca / killer whale (Orcinus orca)
Males: 7 m and 4-5 tonnes, Females: 5.5 m and 3 tonnes
In the past years, orcas were particularly often found in Norwegian waters during the winter because that is when the spring-spawning herring – their main prey – migrate towards land. Lately, the migration has changed and orcas may now be seen regularily in Norwegian waters during all seasons of the year, but they are less concentrated than in the 70-90`s when they overwintered in the Vestfjord/Tysfjord area. Their diet is very varied, composed mainly by fish such as herring and mackerel but also cod-fish, cephalopods, birds, seals and even other cetaceans may be on the meny.
