Origins and Habitat

Assassin snails originate from Southeast Asia, scientifically known as Clea helena or Anentome helena. Their natural habitat includes freshwater rivers, lakes, and ponds where they can dwell amongst sand, rocks, or aquatic plants. Assassin snails prefer slightly acidic to neutral water with a temperature range between 70 and 80 degrees Fahrenheit.

Physical Characteristics

The appearance of assassin snails is unique, with their shells featuring a conical shape and several whorls. The shell’s size typically reaches up to 1 inch in length. The base color of the shell can vary from brown to yellow, with dark brown stripes spiraling around it. This striking pattern allows assassin snails to blend in with their surroundings, making them efficient predators.

Assassin snails have a well-developed foot that allows them to burrow and move around in search of prey. Their tentacles are long and slender, hosting their eyes at the base, which helps them detect movement and locate their prey.

The snail’s siphon is a small tube-like structure used to detect chemical traces in the water, which aids in finding potential prey. The operculum is a rigid plate that seals the shell’s opening when the snail retracts, protecting it from potential threats. As for respiration, assassin snails possess gills to extract oxygen from the water.

Varieties of Assassin Snails

Although Clea helena is the most common species of assassin snail, other varieties have slightly different physical characteristics. Some species may have shells with different patterns, colors, or shapes, but their appearance and behavior remain relatively similar.
