Little Asians
The little assassin snail grows to a length of up to 2.8 centimetres and originates from Asia, where it can be found in both flowing and stagnant waters. When not actively hunting, it likes to bury itself in the substrate to await its next prey. It therefore favours a sandy substrate.
The assassin snail usually has a brown and yellow striped shell although single-coloured varieties also exist. If in danger or if a water body threatens to dry out, for example, the snail can use a plate (Operculum) to close the opening to its shell, sealing it from within. However, it also does this when sleeping to protect itself against possible predators or overly curious fish.
