The European squid or common squid (Loligo vulgaris) is a large squid belonging to the family Loliginidae. It occurs abundantly in coastal waters from the North Sea to at least the west coast of Africa.

The Atlantic Warty Octopus or Unihorn Octopus (Scaeurgus unicirrhus) is a species of octopuses in the family Octopodidae found in Portuguese territory.

The common cuttlefish or European common cuttlefish (Sepia officinalis) is one of the largest and best-known cuttlefish species. The common cuttlefish is native to at least the Mediterranean Sea, North Sea, and Baltic Sea, although subspecies have been proposed as far south as South Africa.

The musky octopus (Eledone moschata) is a species of octopus that lives in the Mediterranean Sea. Eledone moschata is found throughout the Mediterranean Sea, and is occasionally found in adjacent parts of the Atlantic Ocean, around the Gulf of Cadiz and off the coast of Portugal.
