Rumina decollata ‘Decollate Snail’

Description

Scientific Name: Rumina decollata
Common Name: Decollate Snail

Young between 0.5-1.5cm

Rumina decollata, commonly known as the Decollate Snail, is a distinctive terrestrial snail prized for its elongated shell, active behaviour, and unusual appearance. Unlike many land snails, this species develops a tall, tapered shell that naturally loses its upper whorls as it matures, creating the characteristic “decollated” shape that gives the species its name.

Its unique profile immediately sets it apart from more familiar garden snails. Furthermore, its active nature and attractive shell structure make it an excellent display species for naturalistic vivariums and specialist snail collections. Whether observed exploring leaf litter or climbing through a humid enclosure, this fascinating species offers plenty of opportunities for observation.

Native Habitat

Rumina decollata originates from the Mediterranean region, where it inhabits grasslands, scrubland, woodland edges, gardens, and other areas rich in organic matter. These environments provide abundant shelter beneath leaf litter, fallen wood, stones, and other natural cover.

The species thrives in warm conditions with access to moisture while still benefiting from periods of drier weather. Consequently, it adapts well to naturalistic captive environments that replicate these conditions.

Care Information

This species thrives in a well-ventilated enclosure containing a deep substrate rich in organic material. Leaf litter, rotten hardwood, moss, and decaying plant matter should form the foundation of the setup. A moisture gradient is beneficial and allows individuals to regulate their preferred conditions naturally.

Unlike most terrestrial snails kept in the hobby, Rumina decollata is an opportunistic carnivore and scavenger. In nature, it is known to feed on other small snails, slug eggs, and soft-bodied invertebrates, alongside decaying organic matter. Consequently, keepers should provide occasional protein-rich foods such as fish flakes, dried shrimp, insect-based diets, or other suitable invertebrate foods. Due to their predatory tendencies, Decollate Snails should not be housed with smaller snail species that may be viewed as potential prey.

Temperature: 18-25°C
Humidity: Moderate to high humidity with good ventilation
Diet: Leaf litter, decaying plant material, fungi, vegetables, protein-rich foods, small invertebrates, snail eggs, and calcium supplements
Difficulty: Easy

Regular access to calcium is essential for healthy shell growth and maintenance. Therefore, cuttlebone, oyster shell, limestone, or other calcium-rich materials should always be available.

Although this species appreciates humidity, excessive moisture should be avoided. Consequently, maintaining adequate airflow alongside a damp area generally produces the best long-term results.

Breeding Information

Rumina decollata can breed successfully in captivity when maintained under stable conditions with access to quality food and calcium sources. Females deposit eggs within the substrate, where developing young remain protected until hatching.

Juveniles grow steadily when provided with suitable environmental conditions and a varied diet. Furthermore, established colonies often become self-sustaining over time when food and moisture remain consistently available.

Patience is important, as growth rates can vary depending on temperature, nutrition, and enclosure conditions.

Captive-Bred Details

All specimens are captive bred. Captive-bred Rumina decollata adapt well to established enclosures and support sustainable invertebrate keeping.

With its unusual shell structure, active behaviour, and distinctive appearance, Rumina decollata stands out as one of the most interesting terrestrial snails available in the hobby. Whether maintained in a naturalistic display enclosure or incorporated into a bioactive ecosystem, this remarkable species offers a unique and rewarding experience for snail enthusiasts and collectors alike.
