Bithynia leachii
This record describes Bithynia leachii (species). Recorded family: Bithyniidae. Recorded order: Littorinimorpha.
Identification and Appearance
4-7mm. A conical but rounded aquatic snail, usually with just four swollen whorls and a relatively blunt tip. The aperture (mouth) is oval and has an operculum, though this is usually missing if viewing dead shells. The shell is usually light brown (old shells can be discoloured in sediment). Like its larger relative, Bithynia tentaculata, it has long tentacles that extend from the mouth when the animal is moving. Images should show the side profile and the shell aperture. Also state the size. Larger, well-vegetated water bodies such as lakes, canals and ditches. Rarely found in ponds. No additional images available for this species.

About Littorinimorpha: the wider group
Order-level background for Littorinimorpha, the group containing Bithynia leachii. Species-specific details appear above.
Group overview
This is a smaller arthropod order with specialized ecological roles. Arthropods are the most diverse animal phylum, comprising over 80% of all known animal species with approximately 1.2 million described species globally.
Ecological role of the group
Members of this order contribute to broader arthropod ecosystem functions including decomposition, predation, and serving as food sources for vertebrates. Arthropod biodiversity is essential for ecosystem resilience.
Economic and practical significance of the group
While this order has limited direct economic impact, arthropods collectively provide ecosystem services worth trillions of dollars annually through pollination, decomposition, pest control, and nutrient cycling.
