The length of decollate fragment (two whorls) measures 2 mm, the diameter 1 mm.

The shell of the decollate snail is long and roughly cone-shaped. It grows to approximately 40 mm in length, and upon reaching mature size, grinds or chips off the end of its own shell by moving its body roughly against hard surfaces, so that the shell takes on a decollate shape, tapering to a blunt end.

Front view of decollate snail from Austin, Texas Lateral view of decollate snail Rumina decollata is a voracious predator, and feeds readily upon common garden snails and slugs and their eggs. The snail eats plant matter as well, but the damage it causes to plants is considered minor when compared with the benefit of its predation on garden snails and other pest species of snails. Unfortunately it will also consume harmless local species of land gastropods, and beneficial annelids. Decollate snails are tolerant of dry and cold conditions, during which they burrow deep into the soil.

Slug Trap From Recycled Water Bottles The decollate snail (Rumina decollata) will capture and eat garden snails, and because of this it has sometimes been introduced as a biological pest control agent. However, this is not without problems, as the decollate snail is just as likely to attack and devour other species of gastropods that may represent a valuable part of the native fauna of the region.

Molluscivorous birds, such as oystercatchers and the Everglades snail kite, insert their elongate beak into the shell to sever these attachment ligaments, facilitating removal of the prey. The carnivorous terrestrial pulmonate snail known as the "decollate snail" ("decollate" being a synonym for "decapitate") uses a similar method: it reaches into the opening of the prey's shell and bites through the muscles in the prey's neck, whereupon it immediately begins devouring the fleshy parts of its victim. The walrus sucks meat out of bivalve molluscs by sealing its powerful lips to the organism and withdrawing its piston-like tongue rapidly into its mouth, creating a vacuum. Another method is used by many molluscs, themselves.
|
|
The length of the shell varies between 30 mm and 75 mm. (Original description) The decollate, fusiform shell is moderately large, slender and solid. The spire is longer than the aperture . The shell has a broad, somewhat constricted anal fasciole and closely appressed suture, the fasciole chiefly sculptured by incremental lines.

The springs are also located in active oil and gas extraction regions, and pollution of the water is a threat. Fire is also a destructive force in the wildlife refuge habitat. The introduction of the decollate snail (Rumina decollata) is a potential threat, as it could be a predator upon the assiminea.

Length of four whorls, 15.0 mm; of body whorl, 12.5 mm ; of aperture, 9.5 mm ; max. diam. 8.0 mm. (Original description) The small shell is stout, solid, decollate, with a whitish substratum and strong olivaceous periostracum. The four remaining whorls are closely coiled and have the aperture longer than the remaining portion of the spire.
|
|
The length of the decollate holotype attains 16 cm, its diameter 6.25 mm. (Original description) The white shell has a thin, pale olive periostracum. The apex is invariably eroded, and the subsequent whorls, eight or more, are polished and faintly showing incremental lines. The suture is inconspicuous, the anterior margin is sometimes raised like a small cord.
|
|
The (decollate) shell attains a length of 11 mm, its diameter 4.7 mm. (Original description) The shell is small with the protoconch eroded. It is whitish with a dark dull olivaceous periostracum and about five remaining whorls. The suture is appressed, with a broad smooth ridge in front of it and behind the excavated anal fasciole.
|
|
The five whorls have a height of 16 mm and a maximum diameter 5.75 mm. The small, slender shell is elongate. It contains more than 6 flattish whorls (specimen decollate). The suture is distinct, separated from the fasciole in front by an elevated spiral ridge, carinated and beveled from the carina to the suture which is slightly undulated by the ribs.
|

A molluscivore is a carnivorous animal that specialises in feeding on molluscs such as gastropods, bivalves, brachiopods and cephalopods. Known molluscivores include numerous predatory (and often cannibalistic) molluscs, (e.g.octopuses, murexes, decollate snails and oyster drills), arthropods such as crabs and firefly larvae, and, vertebrates such as fish, birds and mammals. Molluscivory is performed in a variety ways with some animals highly adapted to this method of feeding behaviour.

The size of an adult shell varies between 18 mm and 30 mm (Original description) The slender shell slender contains about eight (slightly decollate) whorls. Its color is livid olivaceous with a pale peripheral band, lighter near the aperture. The suture is appressed, on the upper whorls rudely nodulous. The spiral sculpture in front of the fasciole on the spire consists of five or six strong cords with narrower interspaces, overriding the ribs.
|
|
The length of the shell attains 5 mm. (Original description) The shell is decollate and with the aperture imperfect, having evidently the general form of Eubela limacina, but with a slightly more differentiated siphonal canal. The surface is smooth, polished, with a distinct suture in front of which the fasciole appears as a narrow raised band, with an incised line in front of it and marking its edge. The only other sculpture consists of six or seven sharply incised lines on the siphonal canal near its anterior end .

Some animals, such as the song thrush, break the shell of the snail by hammering it against a hard object, such as stone, in order to expose its edible insides. Other predators, such as some species of frogs, circumvent the need to break snail shells by simply swallowing the snail whole, shell and all. Some carnivorous species of snails, such as the decollate snail and the rosy wolf snail, also prey on Helix snails. Such carnivorous snails are commercially grown and sold in order to combat pest snail species.

|
The length of the remaining whorls of the holotype is 8 mm, the diameter 4 mm. (Original description) The small, white shell is decollate, but consists originally of five or more whorls exclusive of the protoconch. The first two remaining intact whorls (the first is eroded) are axial]y sculptured with about 20 close-set obliquely protractive rounded ribs cut by sharp grooves which make of the interspaces rounded nodules, the second row from the preceding suture being more prominent and forming a shoulder to the whorl. There are five of these rows on the spire, and the ribs they represent extend from suture to suture.

The larva of a glowworm (Lampyris noctiluca) attacking and eating a land snail In an attempt to protect themselves against predators, land snails retract their soft parts into their shell when they are resting; some bury themselves. Land snails have many natural predators, including members of all the land vertebrate groups, three examples being thrushes, hedgehogs and Pareas snakes. Invertebrate predators include decollate snails, ground beetles, leeches, certain land flatworms such as Platydemus manokwari and even the predatory caterpillar Hyposmocoma molluscivora. In the case of the marsh snail Succinea putris, the snails can be parasitized by a microscopic flatworm of the species Leucochloridium paradoxum, which then reproduces within the snail's body.

Examples in Chicago sources continued with the term reaching other cities by the end of 1916. By 1917 the term was in widespread use. The first known use in New Orleans, discovered by lexicographer Benjamin Zimmer in 2009, appeared in the New Orleans Times-Picayune on November 14, 1916: > Theatrical journals have taken cognizance of the "jas bands" and at first > these organizations of syncopation were credited with having originated in > Chicago, but any one ever having frequented the "tango belt" of New Orleans > knows that the real home of the "jas bands" is right here.
