  • SHELLFISH/SEAFOODThe main species ofcrustaceans and molluscs
  • CrustaceanSpider Crab•We can find them on the AtlanticEuropean Coast and in theMediterranean Sea.•They live in the rocky bottoms ofthe shoreline, although some ofthese species are migratory.•Males are easily distinguishedfrom females because their clawsare bigger.•In addition, the former shed theircarapace from time to time.
  • Crustacean:Brown Crab/Edible Crab•They are found in the North Sea,North of the Atlantic Ocean andthe Mediterranean Sea.•As most of these species they arenocturnal.•Brown crabs are captured mainlyin France, in Brittany.•Perhaps its most notable featureis their very big and powerfulclaws with a characteristic blacktip.
  • Crustacean:Velvet Crab•We can find them in all shorelineof the European Atlantic Oceanand the Mediterranean Sea.•They are captured mainly inEngland and Scotland where thereare lots because they prefer coldwaters.•Their main predator is octopus, infact the velvet crab is used as baitin the octopus fishing.•Their lateral movement is verycharacteristic of these kinds ofcrabs.
  • Crustacean:Spiny Lobster/RedLobster•In Ireland, Australia, NewZealand and South Africa it iscalled crayfish/crawfish.•They are caught all around theworld because it is regarded adelicacy in a lot of countries.•They have spiny antennae butnot too much developed claws.•Generally they are more or lessreddish but, although less known,they can be greenish too.Obviously their name then isGreen lobster and they areimported from the west coast ofAfrica.
  • Crustacean:European Lobster•Also called Common lobster asopposed to Canadian andAmerican lobsters.•They can be distinguishedthrough their colours. TheEuropean lobster is bluish, in factin Asturias it is named Bluelobster, and the Canadian lobsterhas an orange hue.•Their first pair of legs are twopowerful claws which must be tiedup so as to handle them.
  • Crustacean:Barnacle/Neck GooseBarnacle•They can be found on the PacificCoast of North America, Chile andthe European Atlantic shoreline asfar as the north of Morocco.•Barnacles grow in groups on rocksand they prefer places with strongwaves so their capture is a verydangerous work that most timesincreases their prize.• Although they are crustaceanthey are filter feeder as mollusc.•In Spain it is prized as a delicacyand it is caught in Galicia andAsturias. Barnacles are also eatenin Portugal and France.
  • Crustacean:Prawn King Prawn There are a lot of species all around the world inboth fresh and salt water. Their size is smaller than the king prawn andtheir colour is grey when they are alive ,but theyturn red when they are cooked . In American English they are named shrimps. The colour of this species is pinkish withbrown stripes across its body and its size isbetween 12/15 cm. In Spain the most prized king prawns are fromHuelva.
  • Molluscs:Clam Cockle The word clam is used as the general term forbivalve and especially for the species that liveburied in the mud or sand in the UnitedStates ,but not in the United Kingdom wherethe term is referred to specific species ofclams. In Galicia, the main seller in Spain, they aresowed in the sand so it could be regarded as acrop. We can find them in sandy sheltered beachesthroughout the world. They have rounded shells which aresymmetrical. Their ribbed shell is also a verycharacteristic feature of these molluscs. Sometimes this word is also given to othersmall bivalves so they are known as Truecockles.
  • MolluscsMussel•They can be found all around theworld, but they prefer cold seas.•The mussels shell is black and itsshape is similar to a tear.•They attached themselves to asolid substrate which is normallyrock, but also ships, platforms andanything that is in the sea.•In addition, they are able toreproduce easily so on someoccasions they can become a pest.But generally these behaviourshave been used by men in order togrow them.•The structures for mussel farmingare known as “bateas”.
  • Molluscs:Oyster Scallop Also known as European flat oyster or mudoyster, we can find them on the EuropeanAtlantic Coast and the Mediterranean Sea, butnowadays they also come from sea farming. They are regarded as a delicacy and normallythey are associated with luxury. The common way to eat them is uncookedand only dressed with a bit of lemon. Most species lie on sandy bottoms and whenthey are in danger they are able to get away byswimming. Its shape looks like a fan and its shell is thesymbol of pilgrims who travel to Santiago deCompostela.
