Squid

Squid are cephalopods of the order Teuthida, which comprises around 304 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.

Taxonomy

Squid are members of the class Cephalopoda, subclass Coleoidea, order Teuthida, which has two major suborders, Myopsina and Oegopsina (including giant squid such as Architeuthis dux). Teuthida is the largest cephalopod order with around 300 species classified into 29 families.

The order Teuthida is a member of the superorder Decapodiformes (from the Greek for "ten legs"). Two other orders of decapodiform cephalopods are also called squid, although they are taxonomically distinct from Teuthida and differ recognizably in their gross anatomical features. They are the bobtail squid of order Sepiolida and the ram's horn squid of the monotypic order Spirulida. The vampire squid, however, is more closely related to the octopuses than to any squid.

Fist

A fist is an action where a hand has the fingers curled into the palm and the thumb retracted, displaying the knuckles. There can be an open fist or a closed fist.

Formation of a fist for the purpose of punching is the most basic knowledge taught in the sport of boxing. Fists are taught in martial arts like karate, kung fu, and taekwondo for the process of punching and striking. Fight 100% says "more than 90% of the people actually don't know how to make a fist correctly", and adds that correct formation means the user "won't break [their] hand", "won't strain their wrist", will "be able to launch very powerful punches", and "be able to knock someone out in one punch". Fists are also well-known revolution symbols — as "persistent symbol[s] of resistance and unity", in the form of a raised fist.

Various phenomema, which include the term "fist" in their name such as the sexual act of fisting or the fist bump greeting, involve the use of a fist.

Improper formation of the fist whilst punching or striking an object can cause bruising and broken small bones in the hand known as Boxer's Fracture. Boxer's Fracture occurs when metacarpals or small bones in the hand break on the side of the pinky and ring finger. The name derives from the fact that such injuries are most common in Boxers and practitioners of other fighting arts.

Index (typography)

The symbol ☞ is a punctuation mark, called an index, manicule (from the Latin root manus for "hand" and manicula for "little hand") or fist. Other names for the symbol include printer's fist, bishop's fist, digit, mutton-fist, hand, hand director, pointer, and pointing hand.

History

The symbol originates in scribal tradition of the medieval and Renaissance period, appearing in the margin of manuscripts to mark corrections or notes.

Manicules are first known to appear in the 12th century in handwritten manuscripts in Spain, and became common in the 14th and 15th centuries in Italy with some very elaborate with shading and artful cuffs. Some were playful and elaborate, but others were as simple as "two squiggly strokes suggesting the barest sketch of a pointing hand" and thus quick to draw.

After the popularization of the printing press starting in the 1450s, the handwritten version continued in handwritten form as a means to annotate printed documents. Early printers using a type representing the manicule included Mathias Huss and Johannes Schabeler in Lyons in their 1484 edition of Paulus Florentinus' Breviarum totius juris canonici.
