Euglandina rosea
species of mollusc
Euglandina rosea, the rosy wolfsnail or cannibal snail, is a species of medium-sized to large predatory air-breathing land snail, a carnivorous terrestrial pulmonate gastropod mollusk in the family Spiraxidae.
This species is a fast and voracious predator, hunting and eating other snails and slugs. The rosy wolfsnail was introduced into Hawaii in 1955 as a biological control for the invasive African land snail, Lissachatina fulica. This snail is responsible for the extinction of an estimated eight native snail species in Hawaii. This has caused the snail to be added to the IUCN's top 100 most invasive species.
Description
The rosy wolfsnail lives around 24 months. The snail takes 30–40 days to hatch and is then considered young (before sexual maturity). Sexual maturity begins between 4 and 16 months after hatching. The snail is relatively fast moving at about 8 mm/s. The snail has a light grey or brown body, with its lower tentacles being long and almost touching the ground.
The public source identifies “Euglandina rosea” as species of mollusc. This brief keeps that definition visible, then builds a research path around Euglandina, rosea and species.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Euglandina rosea”, the useful work is to connect “species of mollusc” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q2710885. The Library of Congress control number is sh2007005880. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1955.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
