What species of Mollusks are unique to Argentina?

Hystricomorphy, a unique muskoskeletal pattern involving the jaw, enables the mouth to be opened in a large gape. \n\nHystricomorphy is characteristic of the hystricomorph rodents, but has also now been found in the extinct saber-toothed Barbourofelis. \n\nAlthough it is believed that a highly-detailed phylogenetic analysis should spot the independent acquisition of the two complexes of traits, it is acknowledged that supposedly-unique character complexes could arise through convergence and ‘fool’ the evolutionist into believing that they had arisen from common ancestry. (What qualifies as a chimeric creature?)

Argentina of course, what a question! ;)

Snail shells can be either right-handed (as you\nhave described) or left-handed, although the\nright-handed ones are much more common.  Even\nin the same species of snail an occasional one\nwill come out with handedness opposite to the\nusual.  The handedness seems to be fixed by\nthe tilt of the spindle during the earliest cell\ndivisions of the embryo.  If the spindle leans one\nway the result is a right-handed shell, if it leans the\nother way, left-handed.  Why right-handed is more\ncommon no one seems to know.  It may be just\na historical accident.

It is a mollusk that can partly come out of its body. It has mouth and other feeding organs with the help of which it can feed.

Snails are mollusks; that puts them in the same phylum as clams, oysters and cuttlefish.

There are edible land snails ranging in size from 1/4 inch to giant African snails growing up to 12 inches. The traditional escargot is the common garden-variety snail. Escargot (French for snail) are available fresh, chilled, canned, or frozen.\n\nI thnk the giant African snails might be the best.\n\nSnails are also popular in Portugal, where they are called "caracóis" (Portuguese for "snails"), and served in cheap snack houses and taverns, usually boiled with garlic. Traditional Spanish cuisine is very fond of snails ("caracoles"), too, consuming several species such as Helix aspersa, Helix punctata, Helix pisana or Helix alonensis among others. Small to medium size varieties are usually cooked in several spicy sauces or even in soups, while the bigger ones may be reserved for other dishes such as the "arroz con conejo y caracoles" (a paella-style rice with snails and rabbit meat, very popular in the inner regions of south-eastern Spain) or the many local versions of gazpacho (also a typical meal of meat and vegetables with pieces of unlevened flour cakes).\n\nI live in the Seattle area, slugs are abundant.  It is not exciting to me to eat what I have stepped on in my garden, will not come off until scrubbed with pine-sol!  But this comes out of the mouth aof a woman who loves Dungeness Crab (who eats junk off the bottom of the Puget Sound) so pay no never mind to what grosses me out.  \n\nI think prepartaion is what makes the flavor of the snail. You can buy platters in which to bake snails on.  Real butter seems to really enhance the flavor, garlic too.  \n\nHappy snail eating.  Or Slug munching. Ick.

No, Argentina is in South America. A lot of people living there have ancestors from Spain and Italy, the latter of which is definitely a Mediterranean country. So I would imagine it has some Mediterranean culture.

Yes; their scientific name is Mesocricetus auratus and they belong to family Cricetidae.\n\n--------------\nEDIT: and to think that a week ago I answered this seriously...

snails have a shell, slugs doesn't

none.  They are mollusks.  They do have those hard little beaks, but those are not bones any more than a bird's beak is a bone.

Cephalopod transtates literally to Head Foot.  THey are a class of mollusks that include squids and octopi.

They vary as widely as the body plans of different mollusks, but basically there are both macrophagous (herbivores and predators) and microphagous (suspension feeders) forms.\n \n**Gasteropods (snails and slugs) are mainly herbivorous; they use their radula to scratch plant tissues. However, there are also predatory snails (with modified radula, or proboscis, or even a venom-injecting radula). There are also microphagous planktonic forms (pteropods).\n**Cephalopods (squids, octopi and their relatives) are predatory carnivores, they have a modified radula and a horny "beak" with which they eat different invertebrates and vertebrates.\n**Bivalves (clams, mussels, oysters, etc) are primarily microphagous or suspension (filter) feeders. They don't have a radula and rely on their modified gills for filtration. There are also some primitive detritivores among the bivalvians.\n**The chitons (Polyplacophora) are grazing herbivores (with  radula).\n**The Scaphopoda (tusk shells) capture small food items (particulate matter) with their tentacles (captacula).\n**Other less known mollusks include the caudofoveatans (these capture foraminiferans and other very small organisms from sediments), solenogasters (these eat corals) and monoplacophorans (with a radula, but not much is known about their ecology).

The three species of Lagidium (Lagidium peruanum, L. viscacia, and L. wolffsohni) share a number of cranial features which classify the Family Chinchillidae:  They are hystricognathous (the angular process where the masseter arises is lateral to the plane of the rest of the jaw), and strongly hystricomorphous (in which the infraorbital foramen is enlarged for attachment of the medial masseter muscle).  The mandibles have no masseteric crest, the lacrimals are large and the lacrimal canal opens on the side of the rostrum.  The auditory bullae are enlarged.  The teeth have a pattern of 1/1, 0/0, 1/1, 3/3 = 20) and are hypodont and rootless.  Their molars have two or three closely packed lamellar plates.\n\nSome workers have suggested that the large genetic distances (between 5.9% and 8.9%) between the described species may mean that there are more than the three species of Lagidium that are currently recognized.  Other authors include L. peruanum within L. viscacia, meaning only two species in the Genus.\n\nIf you are looking for the specific characters used to distinguish the different species, I would recommend checking out the following references:\n\nWoods, C. 1993.
