Bladder snail (Physa Acuta)

The Bladder Snail (Physa Acuta) is a fascinating species of freshwater snail that belongs to the class Gastropoda and the family Planorbidae. These snails are known for their unique shell shape, which resembles a urinary bladder, hence their common name.

The Bladder Snail can be found in a wide range of freshwater habitats worldwide, including lakes, ponds, slow rivers, and canals. These snails primarily live in stagnant water or those with very little current, as their fragile shells cannot withstand strong water conditions. They also prefer warmer waters and places with abundant vegetation.

The size of the Bladder Snail ranges from 2 to 2.5 centimeters in length and has a characteristic oval shape. Their shells are typically light in color, generally white or yellow, and the surface is smooth and shiny. Over time, the bladder snail's shell may yellow or even develop uneven spots of darker color.

An interesting aspect of this snail is its respiratory system. The Bladder Snail has a respiratory tube that allows it to come to the water's surface to take in the necessary oxygen. Additionally, these snails have a specialized organ called a pneumostome, located at the top of their bodies, which acts as an opening to the respiratory tube. Through this organ, the Bladder Snail can directly take in oxygen from the atmosphere.

The Bladder Snail is an omnivorous species, feeding on a variety of algae, aquatic plants, and organic matter in the water. These snails play an important role in the aquatic ecosystem by helping maintain ecological balance through the consumption of organic waste and algae, which could otherwise lead to water pollution and toxic algal blooms.

Although Bladder Snails are hermaphroditic, they still require sexual reproduction to produce offspring. The two snails engage in a complex mating ritual, involving the transfer of sperm from one individual to another. After mating, the eggs are deposited in an external gelatinous mass, which adheres to the surface of objects on the water's bottom. These eggs then transform into larvae and eventually into fully developed young snails.

Although the Bladder Snail is a common and widespread species, these snails are sensitive to water pollution and environmental changes. Due to their unique respiratory system and specific habitat preferences, these snails are often used as biological indicators for water quality and the health of aquatic ecosystems.

The Bladder Snail is also used in scientific research and biology laboratories as they are easily raised in captivity and provide a means to study various aspects of their unique biology. Due to their ability to absorb chemicals from the surrounding environment and react to changes in water quality, Bladder Snails are used in studies of toxicology and water pollution monitoring.

In conclusion, the Bladder Snail (Physa Acuta) is a fascinating species of freshwater snail with unique shell shapes and a specialized respiratory system. This snail plays an important role in the aquatic ecosystem, contributing to the maintenance of its health and ecological balance. However, despite being a common and widespread species, it is sensitive to water pollution and environmental changes, making it a valuable indicator of water quality and the health of aquatic ecosystems.









The bladder snail (Physa Acuta) is a freshwater snail that belongs to the family Physidae. It is present in all the fresh waters of the world. The most common area is Europe and North America. It can often be found in Croatia, Germany, the Netherlands, Belarus, the Mediterranean area and Africa. In America it is found mainly in Maryland, New Jersey, and Virginia.

Acute Physa Food

They will feed on dead plants, detritus, leftover fish food, dead fish. A cycled aquarium populated with plants and fish will provide them with enough food for a large population without any additional effort on the part of the owner.

Features Of Acute Physa

They are very easy to care for, which is why the population often grows explosively and is considered harmful, largely because of aesthetics. It does not require special conditions.

They are peaceful snails and are often considered harmful but can be easily combated with killer snails or fish that will eat snails like Botia.

Reproduction Of Acute Physa

Sexual dimorphism: snails are hermaphroditic, meaning they have both male and female reproductive organs but for reproduction it requires the eggs to be fertilized by another individual.

They breed through eggs that they lay in water, on rocks or on the glass of the aquarium and are covered by a protective gelatinous matter. It is an active and fast snail that prefers clean and well oxygenated water. It can also survive in outdoor ponds.
