A squid is a mollusc with an elongated soft body, large eyes, eight arms, and two tentacles in the orders Myopsida, Oegopsida, and Bathyteuthida. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius or pen, made of chitin.
A cephalopod is any member of the molluscan class Cephalopoda such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology.
The giant squid is a species of deep-ocean dwelling squid in the family Architeuthidae. It can grow to a tremendous size, offering an example of abyssal gigantism: recent estimates put the maximum size at around 12–13 m (39–43 ft) for females and 10 m (33 ft) for males, from the posterior fins to the tip of the two long tentacles. The mantle of the giant squid is about 2 m long, and the length of the squid excluding its tentacles rarely exceeds 5 m (16 ft). Claims of specimens measuring 20 m (66 ft) or more have not been scientifically documented.
Sea monsters are beings from folklore believed to dwell in the sea and are often imagined to be of immense size. Marine monsters can take many forms, including sea dragons, sea serpents, or tentacled beasts. They can be slimy and scaly and are often pictured threatening ships or spouting jets of water. The definition of a "monster" is subjective; further, some sea monsters may have been based on scientifically accepted creatures, such as whales and types of giant and colossal squid.
Tentacle erotica is a type of pornography most commonly found in Japan that integrates traditional pornography with elements of bestiality, fantasy, horror, and science fiction. It is found in some horror or hentai titles, with tentacled creatures having sexual intercourse, predominantly with females or, to a lesser extent, males. Tentacle erotica can be consensual but mostly contains elements of rape.
The Dream of the Fisherman's Wife, also known as Girl Diver and Octopi, Diver and Two Octopi, etc., is a woodblock-printed design by the Japanese artist Hokusai. It is included in Kinoe no Komatsu, a three-volume book of shunga erotica first published in 1814, and has become Hokusai's most famous shunga design. Playing with themes popular in Japanese art, it depicts a young ama diver entwined sexually with a pair of octopuses.
Cephalopod intelligence is a measure of the cognitive ability of the cephalopod class of molluscs.
In Caribbean folklore, the Lusca is a name given to a sea monster said to exist in the region of the blue holes nearby Andros, an island in the Bahamas.
The giant squid's elusive nature and fearsome appearance have long made it a popular subject of legends and folk tales. Its popularity as an image continues today with references and depictions in literature, film, television, and video games.
References to the fictional kraken are found in film, literature, television, and other popular culture forms.
Octopodiformes is a superorder of the subclass Coleoidea, comprising the octopuses and the vampire squid. All living members of Octopodiformes have eight arms, either lacking the two tentacles of squid or modifying the tentacles into thin filaments. Octopodiformes is often considered the crown group of octopuses and vampire squids, including all descendants of their common ancestor. Some authors use the term Vampyropoda for the same general category, though others use "Vampyropoda" to refer to the total group. Another term is Octobranchia, referring to cephalopods without prominent tentacles.
The St. Augustine Monster is the name given to a large carcass, originally postulated to be the remains of a gigantic octopus, that washed ashore on the United States coast near St. Augustine, Florida in 1896. It is sometimes referred to as the Florida Monster or the St. Augustine Giant Octopus and is one of the earliest recorded examples of a globster. The species that the carcass supposedly represented has been assigned the binomial names Octopus giganteus and Otoctopus giganteus, although these are not valid under the rules of the ICZN.
Cephalopods, which include squids and octopuses, vary enormously in size. The smallest are only about 1 centimetre (0.39 in) long and weigh less than 1 gram (0.035 oz) at maturity, while the giant squid can exceed 10 metres (33 ft) in length and the colossal squid weighs close to half a tonne (1,100 lb), making them the largest living invertebrates. Living species range in mass more than three-billion-fold, or across nine orders of magnitude, from the lightest hatchlings to the heaviest adults. Certain cephalopod species are also noted for having individual body parts of exceptional size.
All cephalopods possess flexible limbs extending from their heads and surrounding their beaks. These appendages, which function as muscular hydrostats, have been variously termed arms, legs or tentacles.
Cuttlefish, or cuttles, are marine molluscs of the suborder Sepiina. They belong to the class Cephalopoda which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone, which is used for control of buoyancy.
The kraken is a legendary sea monster of enormous size, per its etymology something akin to a cephalopod, said to appear in the sea between Norway and Iceland. It is believed that the legend of the Kraken may have originated from sightings of giant squid, which may grow to 12–15 m in length.
Cephalopod attacks on humans have been reported since ancient times. A significant portion of these attacks are questionable or unverifiable tabloid stories. Cephalopods are members of the class Cephalopoda, which includes all squid, octopuses, cuttlefish, and nautiluses. Some members of the group are capable of causing injury or death to humans.
"The Sea Raiders" is a short story by H. G. Wells, first published in 1896 in The Weekly Sun Literary Supplement. It was included in The Plattner Story and Others, a collection of short stories by Wells published by Methuen & Co. in 1897. It was included in The Country of the Blind and Other Stories, a collection of short stories by Wells published by Thomas Nelson & Sons in 1911.
