Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
I know of only three types: central vacuole - helps maintain plants' shape and structure by storing water (hypotonic). contractile vacuole - pumps water out of protist cells to maintain a suitable concentration. food vacuole - storage for molecules that is a food source for the cell (phagocytosis).
The Contractile Vacoule.
In plant cells there is 1 large vacuole that acts as the main water source for the plant. In animal cells, there are multiple small vacuoles scattered throughout the plant that act as water sources also.

contractile vacuoles merge with the cell membrane..
Contractile vacuoles in protists collect water and then expel it when they become full.
Contractile vacuoles are responsible for regulating osmotic balance in unicellular organisms by expelling excess water. Having mitochondria surrounding the contractile vacuoles helps provide the necessary energy (in the form of ATP) for the vacuoles to pump out water efficiently. This ensures proper functioning of the contractile vacuoles in maintaining cellular homeostasis.
The paramecium might have a contractile vacuole, whereas cells like animal and plants just have a normal one.
Contractile vacuoles in protists collect water and then expel it when they become full.
Contractile vacuoles are primarily found in single-celled organisms, such as protists, that live in freshwater environments. They help regulate the water content of the cell by pumping out excess water to prevent it from bursting. Neither animal nor plant cells typically possess contractile vacuoles.

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.
