The snail feeds on a variety of plants, including economically important crops such as bananas, lettuce, peanuts, and peas. [5] There are also possible public health ramifications of the spread of the snail as an invasive species: it is a carrier of the parasitic rat lungworm, which causes angiostrongyliasis, which in turn is the most common cause of the eosinophilic meningitis or eosinophilic ...
Lymnaea stagnalis, better known as the great pond snail, is a species of large air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Lymnaeidae. The great pond snail is a model organism to study parasitology, neurology, embryonal development and genetic regulation.
The common slow worm, i.e. the species Anguis fragilis, is often called simply "slow-worm", though all species of the species complex comprising the genus Anguis are also called "slow-worms". Common slow worms are semifossorial [2] (burrowing) lizards, spending much of their time hiding underneath objects. The skin of slow worms is smooth with ...
The number of gastropod species can be ascertained from estimates of the number of described species of Mollusca with accepted names: about 85,000 (minimum 50,000, maximum 120,000). [9] But an estimate of the total number of Mollusca, including undescribed species, is about 240,000 species. [ 10 ]
The Vermetidae, the worm snails or worm shells, are a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Littorinimorpha. [1] The shells of species in the family Vermetidae are extremely irregular, and do not resemble the average snail shell, hence the common name "worm shells" or "worm snails".
This finally results in a slow death by starvation. The rosy wolf snail is a hermaphrodite and is oviparous. [3] The courtship rituals for the snail begin with one following the trail of another snail. The pursuing snail then mounts the rear side of the shell of the snail it was following.

The snail's shell is reverse countershaded, because of its upside-down position in the water column. There is a light purple shade on the spire of the shell, and a darker purple on the ventral side. [9] The animal has a large head on a very flexible neck. The eyes are small and are situated at the base of its tentacles.
