Cephalopods – Cephalopoda

Cephalopods are an ancient group of animals that have existed for about 500 million years. Like bivalves and gastropods, they belong to the class Mollusca, although their relationship is not necessarily obvious.

Blue whale

The blue whale is the world's biggest animal, even if we count the enormous dinosaurs that died out more than 60 million years ago. The largest blue whales caught in the Antarctic were up to 32.6 metres long and could weigh up to 190 tonnes.

Lophius piscatorius 06-2015_2.jpg

Anglerfish

Anglerfish in the Northeast Atlantic actually comprise to closely related species. The Norwegian catches are almost exclusively white-bellied anglerfish (Lophius piscatorius), while only a few certain observations are made of the black-bellied anglerfish (L. budegassa).

Stinging jellyfish

Jellyfish are familiar summer visitors to Norway’s beaches and fjords. They are frequently encountered by swimmers and can get caught in fishing nets. In both cases there is a clear and present danger of coming in contact with the tentacles trailing underneath their dome-like mantles where stinging projectiles (called nematocysts) lay waiting to be released.

Sprat

Sprat are schooling fish that live in pelagic waters, and are seldom found deeper than 150 m. They often make vertical migrations relative to fluctuating light of day, and go to the surface when the brightness decreases. In the summer they occur higher in the water column, often near the surface.

Tusk

Tusk is a bottom dweller that prefers stony bottoms on the continental shelf and slope at depths between 100 and 1000 meters. The adults live in relatively deep water, while the juveniles prefer shallow water.

HI-001691.jpg

Fin whale

Fin whales are found in all the oceans of the world and local populations are even found in the Mediterranean. In the southern hemisphere, fin whales reach about 26 metres (females) and 25 metres (males). They are somewhat shorter in the northern hemisphere and weigh from 60–80 tonnes in the south and 40–50 tonnes in the north.

Sea spiders

There is some disagreement as to how sea spiders should be classified, but for a long time they have been considered arthropods. They are marine animals, and are found in all of the oceans and at both poles. Pycnogonida means “with many knees”, and refers to the many segments that make up the legs.

Great scallop are common along the coasts of the North-eastern Atlantic Ocean from the Iberian peninsula in the south to Vestfjorden in the north. They are found on sandy bottom from just below the intertidal zone and down to depths of more than 100 m. In Norwegian waters they are most common at depths of 5–30 m in the counties of Sør-Trøndelag, Nord-Trøndelag and Nordland.

Hooded seals are widespread in the Arctic parts of the North Atlantic. Adults gather in patches in the drifting pack ice during the breeding period in March. Pups born on the ice, where they remain throughout the lactation period, which lasts for four to five days.

HI-017860.jpg

Humpback whale

With its extremely long pectoral fins (a third of its body length), hump on its back and wart-like growths on its upper and lower mandibles, the humpback whale is distinct from the other whales in the fin whale family. The generic name Megaptera is of Greek origin and means ”large-winged" (mega = large; ptera = wing). This obviously refers to the long pectoral fins.

Salmon – Atlantic

The Atlantic salmon is an anadromous fish. They spend their first years in freshwater, and when they are big enough they undergo physiological and morphological changes, and migrate into seawter as a ’smolt’.

HI-029827.jpg

Sea lice

The salmon louse is the most common parasite on farmed salmon, and the biggest disease problem in the aquaculture industry in Norway. Monitoring programs of salmon lice shows that the magnitude of the problem is increasing and that in many cases the lice have become resistant to frequently used treatments such as oral and bath treatments.

HI-036734.jpg

Ling

Ling inhabit various environments: areas of hard or sandy seabeds with scattered large rocks; warm, relatively deep habitats on the continental shelf; on north Atlantic sea banks; in fjords from the Bay of Biscay to Iceland; on the Skagerrak and Kattegat, and in the southwestern Barents Sea. Ling also dwell in the northwest Atlantic from southern Greenland to Newfoundland.

The Atlantic bluefin tuna is the most iconic fish species in the world. It is the largest of all tuna species and one of the largest fish species on our blue planet. They can reach sizes of more than 3 meters in length and weigh more than 700 kg. They can reach swimming speeds of up to 70 km/h, cross the Atlantic Ocean in 50 days and dive deeper than 1000 m depths.

HI-035403.jpg

Porpoise

The porpoise is all small toothed whale about one and a half metres long. In Norway, the porpoise takes its name, "nise", from an Old Norse word for to sneeze. This refers to the sound of the spout when the porpoise comes to the surface to breathe. The porpoise has a dark grey back and somewhat lighter abdomen with a dark stripe from the corner of the mouth to the pectoral fin. Together with five other species, they form the Phocoenidae family.

Spiny dogfish

Several shark species are found in Norwegian waters. The most common are spurdog, velvet-belly lanternshark, Greenland shark, porbeagle and basking shark. Spurdog is one of the most abundant sharks we know, and it has a worldwide distribution. The species is divided into several stocks, and the Northeast Atlantic stock is found from the Bay of Biscay to the Barents Sea.

Polar cod is a pelagic or semi pelagic fish, ie. it lives in the free water masses, but is usually distributed down to the bottom, often in very dense concentrations. It is a cold-water species which thrives best north of the Polar front. 

HI-034608.jpg

Lumpfish

Despite its commercial interest, lumpfish is a poorly studied group, and many aspects of its lifecycle and ecology are unknown. Lumpfish is a semi-pelagic species. The adults are distributed in the open ocean but migrate towards coastal areas to spawn. This happens during the spring season and the males generally arrive at the coast before the females.

HI-035578.jpg

Pacific oyster

The Pacific oyster is easily differentiated from the indigenous European flat oyster by its shape and shell structure. The European flat oyster has a rounded flat shell with a fine, “flaky” surface. The Pacific oyster is usually longer, has a cupped lower shell and a rough surface, often with radial brownish or violet lines.
