Instal Snail limax.io2/20/2024 The nervous system is composed of the typical ganglia. Of the six convolutions of the intestine, four are imbedded in the liver, and two hang freely in the body cavity. The intestine has six convolutions and is without a caecum. Shells of different Limacidae species are undiagnostic: in other words, they are not helpful for identification purpose.ĭigestive system: The formula of the radula is: 62-73/ × 138–157. The length of the shell is 13 mm (1/2 inch) and the width of the shell is 7 mm (1/4 inch). The apex or nucleus is at the posterior margin but inclined towards the left side, and forming the apophysis by which the shell is organically attached to the animal. The shape of the shell is oblong-oval and thin, slightly convex above, and correspondingly concave beneath, with a membranous margin. The calcitic shell is situated beneath the hinder part of the shield, and is perceptible through the skin. The occurrence of this internal shell was known to Pliny the Elder the shell was used by the ancient physicians for the sake of its carbonate of lime. The shell of Limax maximus is reduced and internal, under the shield. Internal anatomy Reproductive system of Limax maximus: Īlthough color varieties have no actual taxonomic significance, a large number of color varieties have been described, prominent among them being the varieties serpentinus, vulgaris, cellarius (typical), johnstoni, maculatus, ferrussaci, obscurus, fasciatus and rufescens, of Alfred Moquin-Tandon, and cornaliee, of Pini. The mucus is colorless and iridescent, and not very adhesive. The pneumostome is just posterior to the midpoint of the mantle, as it is in all Limacidae. The shield is rounded in front, angular behind, and forming an angle of about 80 degrees when in motion, usually of a similar tint to the body, but boldly marbled or maculate with black, somewhat concentrically and interruptedly ridged around a sub-posterior nucleus. The shield is oblong, about one third of the total length of the animal. The reproductive pore is near the base of the right upper tentacle. Drawing of color variability of Limax maximus The foot-fringe is pale, with a row of minute submarginal blackish tubercles. The sole of the foot is a uniform ash or yellowish-ash color. The body is longitudinally streaked or spotted with black. The body color is pale-grey, ash-colored, brownish or sometimes yellowish-white. The greater part of the body is rounded, but there is a short keel on its tail, with about 48 longitudinal rows of elongate, detached tubercles. The body length of the adult is 10-20 cm (4-8 in). This species has a very unusual and distinctive mating method, where the pair of slugs use a thick thread of mucus to hang suspended in the air from a tree branch or other structure.Īlthough native to Europe, this species has been accidentally introduced to many other parts of the world, first discovered outside its native range in Philadelphia, USA in 1867. The adult slug measures 10–20 cm (4–8 in) in length and is generally a light greyish or grey-brown with darker spots and blotches, although the coloration and exact patterning of the body of this slug species is quite variable. Limax maximus is the type species of the genus Limax. It is among the largest keeled slugs, Limax cinereoniger being the largest. Limax maximus (literally, "biggest slug"), known by the common names great grey slug and leopard slug, is a species of slug in the family Limacidae, the keeled slugs.
