Jaws

Jaws is a 1975 American thriller film directed by Steven Spielberg and based on Peter Benchley's novel of the same name. The police chief of Amity Island, a fictional summer resort town, tries to protect beachgoers from a giant man-eating great white shark by closing the beach, only to be overruled by the town council, which wants the beach to remain open to draw a profit from tourists during the summer season. After several attacks, the police chief enlists the help of a marine biologist and a professional shark hunter. Roy Scheider stars as police chief Martin Brody, Richard Dreyfuss as marine biologist Matt Hooper, Robert Shaw as shark hunter Quint, Murray Hamilton as the Mayor of Amity Island, and Lorraine Gary as Brody's wife, Ellen.
Jaws is regarded as a watershed film in motion picture history, the father of the summer blockbuster film and one of the first "high concept" films. Due to the film's success in advance screenings, studio executives decided to distribute it in a much wider release than ever before. The Omen followed suit in the summer of 1976 and then Star Wars one year later in 1977, cementing the notion for movie studios to distribute their big-release action and adventure pictures (commonly referred to as tentpole pictures) during the summer.
Widely regarded as one of the greatest films of all time, Jaws appeared at number 48 on American Film Institute's 100 Years... 100 Movies, a list of the greatest American films of all time, dropping down to number 56 on the 10 Year Anniversary list. It ranked second on a similar list for thrillers, 100 Years... 100 Thrills and was number one on Bravo's list of The 100 Scariest Movie Moments. The film was followed by three sequels, none with the participation of Spielberg or Benchley.

Squids

Squid are marine cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles. Squid are strong swimmers and certain species can 'fly' for short distances out of the water.


 Jellyfish

Jellyfish (also known as jellies or sea jellies or Medusozoa) are free-swimming members of the phylum Cnidaria. Jellyfish have several different morphologies that represent several different cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000–1500 species that make jellyfish and many more that do not). Medusa is another word for jellyfish, and refers to any free-swimming jellyfish stages in the phylum Cnidaria.
Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, are also found in fresh water; freshwater species are less than an inch (25 mm) in diameter, are colorless and do not sting. Many of the best-known jellyfish, such as Aurelia, are scyphomedusae. These are the large, often colorful, jellyfish that are common in coastal zones worldwide.
In its broadest sense, the term jellyfish also generally refers to members of the phylum Ctenophora. Although not closely related to cnidarian jellyfish, ctenophores are also free-swimming planktonic carnivores, are generally transparent or translucent, and exist in shallow to deep portions of all the world's oceans.
Alternative names for groups of jellyfish are scyphomedusae, stauromedusae, cubomedusae, and hydromedusae. These may relate to an entire order or class.

Prawns

Prawns are decapod crustaceans, belonging to the sub-order Dendrobranchiata.^[3] The term "prawn" is also used in various contexts for other animals, especially caridean shrimp.^[4] They are found worldwide and include commercially significant species, such as the whiteleg shrimp Litopenaeus vannamei, Atlantic white shrimp Penaeus setiferus, Indian prawn Fenneropenaeus indicus and tiger prawn Penaeus monodon.

Crabs

True crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (Greek: βραχύς / brachys = short,^[2] οὐρά / οura = tail^[3]), or where the reduced abdomen is entirely hidden under the thorax. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs, horseshoe crabs and crab lice – are not true crabs.
