The pursuing snail then mounts the rear side of the shell of the snail it was following. Rosy wolfsnails use slime trails to track their prey and potential mates, resulting in rosy wolfsnails following these trails more than 80% of the time they are alive. Other forms of control for the rosy wolfsnail have been investigated. Infection occurs by ingesting the bacteria, if they contaminate the snail's food, or by contact with another individual that is infected. The first extinction of 2019 was a snail named George. Cannibalism among adults has also been seen by the rosy wolfsnail. (1989). Non-native predators, such as rats and Jackson’s chameleons, are the greatest threats to kāhuli tree snails. The shell of some specimens can reach 2.75 inches long and the body can reach 4 inches when stretched out! (2020). Following this mounting, a head-waving display occurs, where the pursuing snail vigorously shakes its head for 15 minutes. These snails sometimes burrow under mulch and boards or plywood and they even pursue their prey into water. One strategy to protect the native snails from the predatory rosy wolfsnail has been to breed the native tree snails in captivity, then introduce the small population into a predator-proof patch of forest. Behavioral Neuroscience 117.5:1086-095. Because they feed on snails and slugs that feed on plants, rosy wolf snails can be considered beneficial to landscapes and gardens.  These prey snails were at an increased risk of predation-caused extinction because of their extremely low reproduction rates. In addition, introduced predators such as rats, the predatory rosy wolf snail Euglandina rosea, and Jackson’s chameleons all depredate on Hawai‘i’s native snails. Smaller prey species can even be digested whole given the rosy wolfsnail the nickname “the cannibal snail”. It has a delicate pink shell which belies its carnivorous appetite and ruthless hunting behavior. Chemical poisoning has been used extensively in many areas, though it is not very effective in controlling the population. This forest patch consists of a galvanized iron barrier; at the base of the iron barrier, a plastic trough was attached and filled with salt and then a pair of electric wires connected to a battery. "Factors Affecting Prey Choice And Feeding Technique In The Carnivorous Snail Euglandina Rosea Ferussac." PMID 19459894. The Rosy WolfSnail does not have a direct impact on Humans, but it does kill many native species of Snails in Hawaii, which are very valuable because of their distinct colors of shapes only found in Habitat Description Euglandina rosea is usually found singly in hardwood forests, roadsides and urban gardens in its native range in Florida (Hubricht 1985, University of Florida 2009). The rosy wolf snail, sometimes known as the cannibal snail, is Florida‘s largest predatory air-breathing land snail.  The enclosure allows the native snails to breed in a safe location, but does not allow them to travel outside of the protected area.  The rosy wolfsnail was introduced into Hawaii in 1955 as a biological control for the invasive African land snail, Achatina fulica.  The rosy wolfsnail prefers to consume smaller snails because these are quicker and easier to eat. Image adapted from Yeung et al. • Smooth galvanized aluminum walls and the rolled hood prevent rats and chameleons from climbing the wall.  Due to this, the International Union for Conservation of Nature (IUCN) has placed the rosy wolfsnail on the list of the top 100 worst invasive alien species in the world. A compilation of attacks and feedings of the Rosy Wolf Snail. The radula is enlarged and has teeth specialized into elongated cones.

Kluwer Academic Publishers. The rosy wolf snail has a long, light brown shell, and the body is light gray to brown. Somespecies, though, also settled in the area of the Mediterranean. Triangles mark records of A. gagneorum’s range since 2010 while circles represent its historic range based on specimens collected in the 1940s. The rosy wolf snail uses its lappets to follow the slime trails of prey.  This has caused the snail to be added to the IUCN’s top 100 most invasive species. Wolf snails are are part of the mainly neotropicland snail family of Oleacinidae, whose area of distribution spread fromSouthern and Central America up into the South Eastern United States. This did not, however, reduce the populations of A. fulica, but rather caused a decline in native snail populations. The rosy wolf snail is a hermaphrodite and is oviparous; it has both male and female reproductive parts and lays eggs instead of giving live birth. These predatory snails were originally introduced to Hawaii in an attempt to eliminate another invasive species, the giant African land snail, Achatina fulica. It has expanded its range from disturbed areas infested with A. fulica and spread into the native forests, into higher elevations where Hawaiian endemic tree snails are found. This means that live individuals cannot be brought to the islands. It also is known from several of the islands in the Caribbean region and from Costa Rica.

The American snail had been introduced for the islands in an attempt to wipe out the African giant land snail, that had been previously introduced, but it preyed upon the tiny native Partula snails instead. However, the species came close to extinction in the 1980s after the rosy wolf snail from Florida was introduced in the 1970s. . No control seems necessary for rosy wolf snails (unless you are concerned about preserving native molluscs!). After a rain, rosy wolf snails may gather in small numbers to mate.
