The rosy wolf snail ( Euglandina rosea ) is a predatory land snail from the family of Spiraxidae , native to North America ; this family belongs to the subordination of land snails (Stylommatophora).
features
The right-hand wound, spindle-shaped, almost transparent housing is about 7.6 cm, sometimes 10 cm long in the adult animal and reaches a diameter of about 2.8 cm. The case mouth is egg-shaped to crescent-shaped, the spindle cut off. The surface has clear growth stripes and is typically brown to brownish pink. The snail itself is also brown in color. The lower feelers almost touch the ground. Compared to other members of the Spiraxidae family, the rosy wolf snail has particularly long labial palps - two tentacle-like appendages on the front end of the foot in the mouth area.
Occurrence, way of life and distribution
The rosy wolf snail can be found in forests, on roadsides and in gardens. It mainly eats other shell snails. Smaller prey animals are completely devoured with the shell, whereby the lime is also used by the wolf snail. With larger prey, pieces of meat are cut out and devoured with the help of the radula . The snail also penetrates into the furthest turns in order to completely devour the prey.
The snail has its natural range in tropical North America, in the USA in Alabama , Florida , Georgia , Louisiana , Mississippi , South Carolina and in southeastern Texas . It was released in Hawaii and French Polynesia to control the introduced agate snail, Achatina fulica , but is now linked as an invasive species to the disappearance of native tree snail species (families Achatinellidae , Amastridae and Partulidae ).
Systematics
The rosy wolf snail belongs to the subfamily Euglandininae (Baker 1941) and traditionally belongs to the Oleacinidae , but according to Thompson (2010) it belongs to the Spiraxidae .
