because marine species are usually in isotonic equilibrium with their environment.
That's correct, marine protozoa do not have contractile vacuoles. Contractile vacuoles are typically found in freshwater protozoa and serve to regulate water balance by expelling excess water from the cell. Marine protozoa have adaptations to maintain water balance in a high-salt environment without the need for contractile vacuoles.
Contractile Vacuole
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
paramecium has the contractile vacuole yooo!
plasma membrane. it controls the water movement through osmosis.

A contractile vacuole is present in a paramecium protozoa but absent in the cells of a strawberry plant. The contractile vacuole helps regulate water content in paramecium cells by expelling excess water, a function not needed in plant cells due to their rigid cell walls.

The Contractile Vacoule.
The contractile vacuole is the structure in amoeba responsible for expelling excess water and maintaining osmotic balance within the cell. It collects and removes the excess water by contracting and expelling it out of the cell.
The contractile vacuole is an organelle found in some unicellular organisms, such as protozoa, that functions to regulate osmotic pressure by expelling excess water from the cell. This helps maintain cellular homeostasis and prevents the cell from bursting due to osmotic influx. Without the contractile vacuole, these organisms would struggle to manage water balance, leading to potential cell lysis and ultimately impairing their survival in freshwater environments.
contractile vacuole
No, an amoeba typically has one contractile vacuole, which is responsible for expelling excess water and waste from the cell. The contractile vacuole helps to regulate the osmotic balance of the cell by maintaining the proper water content.
