This handle usually carries the latch. Choil The unsharpened portion of the blade just above the kicker, that makes it easier to sharpen the blade.
Gladius, showing measurement of rachis and vane. The gladius (pl.: gladii), or pen, is a hard internal bodypart found in many cephalopods of the superorder Decapodiformes (particularly squids) and in a single extant member of the Octopodiformes, the vampire squid (Vampyroteuthis infernalis). [1]
Cephalopod limbs bear numerous suckers along their ventral surface as in octopus, squid and cuttlefish arms and in clusters at the ends of the tentacles (if present), as in squid and cuttlefish. [9] Each sucker is usually circular and bowl-like and has two distinct parts: an outer shallow cavity called an infundibulum and a central hollow ...
The beak of a giant squid. All extant cephalopods have a two-part beak, or rostrum, situated in the buccal mass and surrounded by the muscular head appendages. The dorsal (upper) mandible fits into the ventral (lower) mandible and together they function in a scissor-like fashion. [1] [2] The beak may also be referred to as the mandibles or jaws ...
The same is true of the chitinous gladius of squid [83] and octopuses. [84] Cirrate octopods have arch-shaped cartilaginous fin supports, [85] which are sometimes referred to as a "shell vestige" or "gladius". [86] The Incirrina have either a pair of rod-shaped stylets or no vestige of an internal shell, [87] and some squid also lack a gladius ...
However, other studies have recovered it as an oegopsid squid. [3] Orthocone nautiloids range in size from less than 25 mm (1 in) to (in some giant endocerids of the Ordovician) 5.2 m (17 ft) long. Orthocone cephalopod fossils are known from all over the world, with particularly significant finds in Ontario, Canada and Morocco.
The squid’s common name refers to the area where it lives. The Ryukyu Islands are a chain of 55 islands in the west Pacific Ocean and stretch about 700 miles from southwest Japan to northeast ...
The image was published in the 1993 book European Seashells by Guido T. Poppe and Goto Yoshihiro, where it was identified as Architeuthis dux, the giant squid, and said to have been taken in the North Atlantic. [12] [clarification needed] If true, this image would represent the earliest known photograph of a live giant squid. [11]
