What is "squid"

Squid \Squid\ (skw[i^]d), n. [Cf. Squirt.]

1. (Zo["o]l.) Any one of numerous species of ten-armed cephalopods having a long, tapered body, and a caudal fin on each side; especially, any species of Loligo, Ommastrephes, and related genera. See Calamary, Decacerata, Dibranchiata.

   Note: Some of these squids are very abundant on the Atlantic coast of North America, and are used in large quantities for bait, especially in the cod fishery. The most abundant of the American squids are the northern squid ( Ommastrephes illecebrosus), ranging from Southern New England to Newfoundland, and the southern squid ( Loligo Pealii), ranging from Virginia to Massachusetts.

2. A fishhook with a piece of bright lead, bone, or other substance, fastened on its shank to imitate a squid.

   Flying squid, Giant squid. (Zo["o]l.) See under Flying, and Giant.

   Squid hound (Zo["o]l.), the striped bass.

marine mollusk, cuttlefish, 1610s, of unknown origin; perhaps a sailors' variant of squirt, so called for the "ink" it squirts out.

Etymology 1 n. 1 Any of several carnivorous marine cephalopod mollusks, of the order Teuthida, having a mantle, eight arms, and a pair of tentacles 2 A fishhook with a piece of bright lead, bone, or other substance fastened on its shank to imitate a squid. 3 (context mildly pejorative English) A sailor in the Navy. 4 (context UK slang humorous rare English) A quid; one pound sterling. Etymology 2

n. (context slang motorcycling pejorative English) A motorcyclist characterized by lack of riding gear, reckless/careless/unsafe riding, especially of sport bikers.

1. n. (Italian cuisine) squid prepared as food [syn: calamari, calamary]

2. widely distributed fast-moving ten-armed cephalopod mollusk having a long tapered body with triangular tail fins

3. [also: squidding, squidded]

A SQUID (for superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions.

SQUIDs are sensitive enough to measure fields as low as 5 a T (5×10 T) within a few days of averaged measurements. Their noise levels are as low as 3 fT· Hz. For comparison, a typical refrigerator magnet produces 0.01 tesla (10 T), and some processes in animals produce very small magnetic fields between 10 T and 10 T. Recently invented SERF atomic magnetometers are potentially more sensitive and do not require cryogenic refrigeration but are orders of magnitude larger in size (~1 cm) and must be operated in a near-zero magnetic field.

Squid is a caching and forwarding web proxy. It has a wide variety of uses, from speeding up a web server by caching repeated requests; to caching web, DNS and other computer network lookups for a group of people sharing network resources, to aiding security by filtering traffic. Although primarily used for HTTP and FTP, Squid includes limited support for several other protocols including TLS, SSL, Internet Gopher and HTTPS.

Squid was originally designed to run as a daemon on Unix-like systems. A Windows port was maintained up to version 2.7. New versions available on Windows use the Cygwin environment. Squid is free software released under the GNU General Public License.

A squid is a type of marine cephalopod with ten limbs.

Squid was a British World War II ship-mounted anti-submarine weapon. It consisted of a three-barrelled mortar which launched depth charges. It replaced the Hedgehog system, and was in turn replaced by the Limbo system.

Literally ordered directly from the drawing board in 1942, under the auspices of the Directorate of Miscellaneous Weapons Development, this weapon was rushed into service in May 1943 on board HMS Ambuscade. The first production unit was installed on HMS Hadleigh Castle, it went on to be installed on 70 frigates and corvettes during the Second World War. The first successful use was by HMS Loch Killin on 31 July 1944, when she sank U333; the system was credited with sinking 17 submarines in 50 attacks. By 1959, 195 Squid installations had been produced. This weapon was a three-barrel mortar with the mortars mounted in series but off-bore from each other in order to scatter the projectiles. The barrels were mounted in a frame that could be rotated through 90 degrees for loading. The projectiles weighed with a minol charge. On some vessels, the Squid installations were at the stern – the bombs were fired over the length of the ship and dropping into the sea slightly ahead of it. Sink rate was 43.5 ft/s (13.3 m/s) and a clockwork time fuse was used to determine the detonation depth; all three projectiles had to be set to the same depth; this could be continuously updated right up to the moment of launch to take into account the movements of the target. The maximum depth was . The weapons were automatically fired from the sonar range recorder at the proper moment. The pattern formed a triangle about 40 yards (37 m) on a side at a distance of 275 yards (250 m) ahead of the ship. Most Squid installations utilised two sets of mortars. All six bombs were fired in salvo so they formed opposing triangular spreads. The salvos were set to explode above and below the target, the resulting pressure wave crushing the hull of the submarine. Postwar trials found Squid was nine times more effective than conventional depth charges.

Despite its proven effectiveness, some officers, notably Captain Kenneth Adams, RCN, opposed fitting Squid to escorts because it meant sacrificing guns, which would make ships unsuitable for fleet actions.

In April 1977, the Type 61 frigate Salisbury became the last ship to fire Squid in Royal Navy service. Examples of the mortars are on display at the Explosion! Museum of Naval Firepower in Gosport, Hampshire and another at Devonport Naval Base. In addition, the system is fitted to , which is part of the historic ships collection in the Historic Dockyard in Chatham, Kent.
