The common octopus (Octopus vulgaris) is the most studied of all octopus species. Its range in the eastern Atlantic extends from the Mediterranean Sea and the southern coast of England to at least Senegal in Africa. It also occurs off the Azores, Canary Islands, and Cape Verde Islands. The species is also common in the Western Atlantic.

The Greenland halibut or Greenland turbot (Reinhardtius hippoglossoides) belongs to the Pleuronectidae family (the right eye flounders), and is the only species of the genus Reinhardtius. It is a deepwater fish distributed from 200 to 1600 m but has been caught at depths more than 2,200 m . It is mainly found in waters with temperatures from 1-4 °C, but has also observed at sub-zero temperatures down to -2.1 °C. It has a circumpolar distribution and is found in both the Atlantic and the Pacific oceans. Its morphology with the left eye positioned on the dorsal ridge of the forehead gives it an appearance of a cyclops when looking straight at it. The central position of the left eye in the Greenland halibut probably gives it a much wider range of peripheral vision in comparison to other flatfish where the eye has migrated completely. The body shape is elongated and compressed dorsal-ventrally and muscles on both sides are equally developed. Both sides are pigmented; however the left blind side is slightly lighter in color than the right side. Its physical appearance suggests it to be a vigorous swimmer that can swim in a vertical position. Vertical swimming has been observed during tagging experiments. However, video analyzing of Greenland halibut behavior in front of a bottom trawl showed no sign of swimming in a vertical position. Even though most Greenland halibut are caught in bottom fishing gears (trawl, longline and gillnet) they have also been caught in surface drift nets which indicates that they can have a pelagic occurrence. Stomach analysis has also shown that the diet consists mostly of pelagic or bathypelagic organisms. Even though the Greenland halibut is a flatfish it does at times behave more like a roundfish.

The haddock (Melanogrammus aeglefinus) is a marine fish distributed on both sides of the North Atlantic. Haddock is a popular food fish and is widely fished commercially.

The common ling or simply the ling, Molva molva, is a large member of a family of cod-like fishes. An ocean fish whose habitat is in the Atlantic region and can be found around Iceland, Faroe Islands, British Isles, the Norse coast and occasionally around Newfoundland, the ling has a long slender body that can reach 2 metres in length; in adulthood, it is generally a deep-running fish, spending much of its life at depths of 100 m or more; younger fish are found at shallower depths. The ling is edible; its flesh is prized and can be considered interchangeable with cod in either its fresh, salted or dried forms. The salted roe of the ling is considered a delicacy in Spain and is known as huevas de maruca. The lutefisk – ling that is first dried, then soaked in water and then steeped in a lye of soda and slaked lime – is a traditional dish at the Christmas table in Sweden, Norway and Finland.

The northern pike (Esox lucius), known simply as a pike in Britain, Ireland, Canada, and most parts of the USA, also called jackfish or simply "northern" in the Upper Midwest of the USA), is a species of carnivorous fish of the genus Esox (the pikes). They are typical of brackish and fresh waters of the Northern Hemisphere (i.e. holarctic in distribution). Pike grow to a relatively large size; lengths of 150 cm (59 in) and weights of 25 kg (55 lb) are not rare. The average length is about 70-120 cm (28-47 in). The heaviest specimen known so far was caught in 1983 at an abandoned stone quarry in Germany, where the species is known as a Hecht. She (the majority of all pikes over 8 kg or 18 lb are females) was 147 cm (58 in) long and weighed 31 kg (68 lb). The longest pike ever recorded and confirmed was 152 cm (60 in) long and weighed 28 kg (62 lb). A pike of 60.5 in (154 cm) was caught and released in May 2004 in Apisko Lake, Manitoba. Historic reports of giant pike, caught in nets in Ireland in the late 19th century, of 41-42 kg (90-93 lb) with a length of 173-175 cm (67-68 in), were researched by Fred Buller and published in The Domesday Book of Mammoth Pike.

The rainbow trout (Oncorhynchus mykiss) is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America. The steelhead is a sea-run rainbow trout usually returning to freshwater to spawn after two to three years at sea; rainbow trout and steelhead trout are the same species. The fish are often called salmon trout. Several other fish in the salmonid family are called trout; some are anadromous like salmon, whereas others are resident in freshwater only. The species has been introduced for food or sport to at least 45 countries, and every continent except Antarctica. In some locations, such as Southern Europe, Australia and South America, they have negatively impacted upland native fish species, either by eating them, outcompeting them, transmitting contagious diseases, or hybridization with closely related species and subspecies that are native to western North America.

Salmonidae are a family of ray-finned fish, the only living family currently placed in the order Salmoniformes. It includes salmon, trout, chars, freshwater whitefishes and graylings. The Atlantic salmon and trout of genus Salmo give the family and order their names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They are slender fish, with rounded scales and forked tails. Their mouths contain a single row of sharp teeth. Although the smallest species is just 13 centimetres long as an adult, most are much larger, and the largest can reach 2 metres . All salmonids spawn in fresh water, but in many cases, the fish spend most of their lives at sea, returning to the rivers only to reproduce. This life cycle is described as anadromous. They are predators, feeding on small crustaceans, aquatic insects, and smaller fish.

Pollock (alternatively spelled pollack) is the common name used for either of the two species of marine fish in the Pollachius ("P.") genus. Both P. pollachius and P. virens are commonly referred to as pollock. Other names for P. pollachius include the Atlantic pollock, European pollock, lieu jaune, and lythe; while P. virens is sometimes known as Boston blues (distinct from bluefish), coalfish (or coley), silver bills or saithe.

Gadus is a genus of demersal fish in the family Gadidae, commonly known as cod, although there are additional cod species in other genera. Until recently, three species in the genus were recognized. Modern taxonomy also includes a fourth one, the Alaska pollock (Gadus chalcogrammus), which is not separate from the Norway pollock. Furthermore, Greenland cod (G. ogac) is no longer considered a distinct species but rather a subspecies of Pacific cod (G. macrocephalus).

Clupeinae is a subfamily of herrings, sardines and sprats belonging to the family Clupeidae.

Perciformes, also called the Percomorphi or Acanthopteri, are the largest order of vertebrates, containing about 40% of all bony fish. Perciformes means "perch-like". They belong to the class of ray-finned fish, and comprise over 10,000 species found in almost all aquatic ecosystems.

The term shrimp is used to refer to some decapod crustaceans, although the exact animals covered can vary. Used broadly, it may cover any of the groups with elongated bodies and a primarily swimming mode of locomotion – chiefly Caridea and Dendrobranchiata. In some fields, however, the term is used more narrowly, and may be restricted to Caridea, to smaller species of either group, or to only the marine species. Under the broader definition, shrimp may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long narrow muscular tails, long whiskers and slender legs. They swim forwards by paddling with swimmerets on the underside of their abdomens. Crabs and lobsters have strong walking legs, whereas shrimp have thin fragile legs which they use primarily for perching. Shrimp are widespread and abundant. They can be found feeding near the seafloor on most coasts and estuaries, as well as in rivers and lakes. To escape predators, some species flip off the seafloor and dive into the sediment. They usually live from one to seven years. Shrimp are often solitary, though they can form large schools during the spawning season. There are thousands of species, and usually there is a species adapted to any particular habitat. Any small crustacean which resembles a shrimp tends to be called one. They play important roles in the food chain and are important food sources for larger animals from fish to whales. The muscular tails of shrimp can be delicious to eat, and they are widely caught and farmed for human consumption. Commercial shrimp species support an industry worth 50 billion dollars a year, and in 2010 the total commercial production of shrimp was nearly 7 million tonnes (see production chart on the right). Shrimp farming took off during the 1980s, particularly in China, and by 2007 the harvest from shrimp farms exceeded the capture of wild shrimp. There are significant issues with excessive bycatch when shrimp are captured in the wild, and with pollution damage done to estuaries when they are used to support shrimp farming. Many shrimp species are small as the term shrimp suggests, about 2 cm long, but some shrimp exceed 25 cm . Larger shrimp are more likely to be targeted commercially, and are often referred to as prawns, particularly in Britain.

Crayfish – also called crawfish or crawdads – are freshwater crustaceans resembling small lobsters, to which they are related; taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills and are found in bodies of water that do not freeze to the bottom. They are mostly found in brooks and streams where there is fresh water running, and which have shelter against predators. Most crayfish cannot tolerate polluted water, although some species such as the invasive Procambarus clarkii are more hardy. Crayfish feed on living and dead animals and plants. In Australia, New Zealand and South Africa, the term crayfish or cray generally refers to a saltwater spiny lobster, of the genus Jasus that is indigenous to much of southern Oceania, while the freshwater species are usually called yabby, from the indigenous Australian and Maori names for the animal respectively, or by other names specific to each species. An exception is the freshwater Murray crayfish, which belongs to the family Parastacidae and is found on Australia's Murray River.

A flatfish is a member of the order (Pleuronectiformes) of ray-finned demersal fishes, also called the Heterosomata, sometimes classified as a suborder of Perciformes. In many species, both eyes lie on one side of the head, one or the other migrating through and around the head during development. Some species face their left side upward, some face their right side upward, and others face either side upward. Many important food fish are in this order, including the flounders, soles, turbot, plaice, and halibut. There are more than 400 species of this order. Some flatfish can camouflage themselves on the ocean floor.

Frozen dessert is the generic name for desserts made by freezing liquids, semi-solids, and sometimes even solids. They may be based on flavored water (shave ice, sorbet, snow cones, etc.), on fruit purées (such as sorbet), on milk and cream (most ice creams), on custard (frozen custard and some ice creams), on mousse (semifreddo), and others.

A cracker is a baked good typically made from grain flour dough and usually manufactured in large quantities. Crackers (equivalent to savory biscuits in the UK) are usually flat, crisp, small in size and are made in various shapes, though are commonly round or square. Flavorings or seasonings, such as salt, herbs, seeds, and/or cheese, may be added to the dough or sprinkled on top before baking. Crackers are eaten on their own, or can accompany other food items, such as cheese or meat slices, or dips. [Wikipedia]

Vegetable juice is a drink made primarily of blended vegetables. Vegetable juice is often mixed with fruits such as tomatoes or grapes to improve flavor. It is often touted as a low-sugar alternative to fruit juice, although some commercial brands of vegetable juices use fruit juices as sweeteners, and may contain large amounts of sodium.

A soft drink (also called a soda, pop, coke, soda pop, fizzy drink, tonic, or carbonated beverage) is a non-alcoholic beverage that typically contains water (often, but not always carbonated water), a sweetener, and a flavoring agent. The sweetener may be sugar, high-fructose corn syrup, or a sugar substitute (in the case of diet drinks). A soft drink may also contain caffeine, fruit juice, or both. Widely sold soft drink flavors are cola, lemon-lime, root beer, orange, grape, vanilla, ginger ale, fruit punch, and sparkling lemonade. Soft drinks may be served chilled or at room temperature. They are rarely heated. [Wikipedia]
