Together with the cuttlefish and the dwarf cuttlefish, squids are among the ten-armed squids, most of which are strictly night-active. Two of their ten arms, which are heavily prolonged and are provided with suction cups only at their thickened end, can be vorgeschleuderted quickly, depending on the type of fish or crustaceans. While cuttlefish and dwarf cuttlefish live as loners on the ground, Squids are predominantly inhabitants of the free water and can, in particular to reproductive time, form some huge swarms.
The Loligo vulgaris, which is up to a maximum of 50 cm long and weighs up to 1.5 kg, which is found in the coastal waters of the northeast Atlantic including the North Sea and the Mediterranean Sea, is hunting for small fish that sleep in the open water at night. Encounters with larger groups as in the photo are extremely rare and represent an absolute highlight!
