Euglandina rosea

Field Notes
Description:
The rosy wolfsnail has a light brown elongated shell and a light grey or brown body. Its lower tentacles are long and almost touch the ground. The shell is often 40 to 50 mm in maximum dimension but can sometimes be as large as 60 or even 70 mm. The immature snails have a shorter shell and can be almost appear yellow in color.
Habitat:
Euglandina rosea can be found in hardwood forests, roadsides and urban gardens.
Notes:
According to the Global Invasive Species Database (issg.org), Euglandina rosea is considered one of the world's 100 worst invaders. The presence of Euglandina rosea has been strongly linked to the extinction and decline of numerous snail species in every area where it has been introduced. Conservationists are working to prevent the further spread of Euglandina rosea. “Exclosures” have been built in Hawaii and French Polynesia to prevent E. rosea from attacking native tree snails. These barriers are somewhat successful but require constant monitoring and maintenance. A toxic bait using snails from the genus Pomacea is being tested in Hawaii.
