Description:

Example species: Minke whale

Habitat: Pelagic
Main role: Predator

Diet: Their diet is dominated by fish: mostly sandeel, but also herring, mackerel and gadoids such as whiting, haddock, and Norway pout.

Threats: Minke whales are sensitive to entanglement in fishing gear and boating accidents. Fishing can deplete their food resources.


Example species: Porpoise

Habitat: Pelagic
Main role: Predator
Trophic level: 4,8

Diet: Porpoises prey on whiting and sandeel.

Threats: Sensitive to entanglement in fishing nets and fishing depletion of food resources.


Example species: White-beaked dolphin

Habitat: Pelagic
Main role: Predator
Trophic level: 4,8

Diet: They prey on whiting and cephalopods.

Threats: Sensitive to entanglement in fishing nets and fishing depletion of food resources.
