Physical Characteristics:

• Physella is a genus of small to medium-sized freshwater snails.
• Their shells are typically thin, fragile, and often translucent.
• The shell is sinistral, meaning it coils to the left, which is a distinguishing feature.

Habitat and Distribution:

• Physella species are commonly found in freshwater habitats such as ponds, streams, and lakes.
• They prefer slow-moving or still waters with plenty of aquatic vegetation.
• In the Comunidad Valenciana, they can be found in various freshwater environments, supporting a rich aquatic ecosystem.

Behavior and Diet:

• Physella snails are herbivorous, feeding on algae, detritus, and plant material.
• They play an essential role in the aquatic ecosystem by helping to control algae growth.
• These snails are often seen grazing on submerged surfaces.

Reproduction:

• Physella snails are hermaphrodites, possessing both male and female reproductive organs.
• They can self-fertilize or cross-fertilize with other snails, laying eggs in gelatinous clusters.
• Reproduction occurs throughout the warmer months, leading to multiple generations each year.

Overall, Physella snails are an integral part of freshwater ecosystems within the Comunidad Valenciana, contributing to biodiversity and ecological balance.
