Tail fin of Giant Squids (?) Explanation: Definition: widely distributed fast-moving ten-armed cephalopod mollusk having a long tapered body with triangular tail fins . http://en.wikipedia.org/wiki/Giant_squid & http://www.answers.com/topic/squid Squid The common name applied to cephalopods of the order Teuthoidea. They are marine mollusks that inhabit the oceans of the world. Squids are characterized by having eight arms and two longer tentacles around the mouth; an elongated, tapered, usually streamlined body; an internal rod- or bladelike shield (gladius); and fins on the body (mantle). The arms have two (infrequently four or six) rows of suckers and occasionally clawlike hooks, and the tentacles have terminal clubs with suckers, hooks, or both. The muscular, elastic tentacles are contractile, not retractile into pockets like those of cuttlefishes (Sepioidea). See also Sepioidea. Squids have an exceptionally well-developed brain and organs of the central nervous system that approach in complexity and function those of fishes and even some birds and mammals. Squids are active, powerful swimmers, driven by jet propulsion as water taken into the mantle cavity is forcefully expelled through the funnel. Prey, normally shrimps, fishes, or other squids, are captured with the two tentacles and held with the arms while the beaks cut off bites that the radula and tongue shove down the throat. See also Nervous system (invertebrate). Two groups (suborders) of squids are recognized: Myopsida and Oegopsida. See also Cephalopoda; Coleoidea. Any of nearly 400 species of 10-armed cephalopods, found in both coastal and oceanic waters, that prey on fishes and crustaceans. They range from less than 0.75 in. (1.5 cm) to more than 65 ft (20 m) long (in the case of the giant squid). Two of the 10 arms are long, slender tentacles; each has an expanded end and four rows of suckers with toothed, hard-edged rings. An internal shell supports the slender tubular body of most species. Squid eyes, almost as complex as human eyes, are usually set into the sides of the head. Squids may be swift swimmers (propelling themselves by contracting and relaxing their mantle or by undulating their two fins) or mere drifters; water expelled from a funnel below the head can propel the squid backward. Like the octopus, the squid may emit an inky cloud from its ink sac when in danger from sperm whales, fishes, or humans, among other predators.

Perdón mi ignorancia .... la concha es interna, muy reducida y de naturaleza córnea, ésta recibe el nombre de pluma (part of Barbara's note). |

internal shell Explanation: A los primeros pertenecen los calamares, las sepias o jibias y los chopos; son moluscos de cuerpo alargado, provistos de aletas laterales de forma triangular que llevan alrededor de la boca una corona de ocho brazos de longitud semejante entre sí y otros dos más largos; la concha es interna, muy reducida y de naturaleza córnea, ésta recibe el nombre de pluma. The squid, a representative cephalopod, shows several variations on the mollusk body plan. With a name meaning “head-footed,” the cephalopod’s “foot,” which is single and large in most other mollusks, is divided into sucker-bearing arms, or tentacles, specialized for drawing food into the animals’ beaklike jaws. Another cephalopod adaptation is the mantle. Highly muscular, it forces water from the cavity through the tubular siphon to propel the animal quickly through the water. Most notable perhaps is the internal shell, greatly reduced from the large external shells of other mollusks. This shell is entirely absent in octopuses. -------------------------------------------------- Note added at 3 hrs (2006-11-27 02:35:43 GMT) -------------------------------------------------- more info PEN: http://ca.encarta.msn.com/encyclopedia_761576141/Cephalopod.... More advanced cephalopods are exemplified by the squid and cuttlefish, in which the shell is reduced and covered by tissue. The squid has a thin, horny, internal shell called a pen.
