The amoeba has no definite form.
The name for a protozoan of ever changing shape is Amoeba. Amoebas are single-celled organisms that constantly alter their shape as they move and feed.

Amoeba: A common unicellular protozoan that moves and feeds using pseudopods. Paramecium: A ciliated protozoan with a characteristic slipper-like shape. Trypanosoma: A parasitic protozoan that causes diseases like sleeping sickness and Chagas disease. Plasmodium: A protozoan parasite responsible for causing malaria in humans. Giardia: A flagellated protozoan that can cause gastrointestinal issues in humans and other animals.
microscopic protozoan
Protozoan parasites are single-celled eukaryotic organisms, while bacteria are prokaryotes. Protozoan parasites are generally larger and have more complex cellular structures compared to bacteria. Additionally, protozoan parasites often have more specialized modes of transmission and lifecycle strategies that are adapted to living within a host organism.

If a saltwater protozoan is transferred to a freshwater lake, it will likely face osmotic stress due to the significant difference in salinity. The freshwater environment can cause water to enter the protozoan's cells rapidly, potentially leading to cell swelling and rupture, a process known as osmotic lysis. Most saltwater organisms are not adapted to handle such drastic changes in salinity, so the protozoan is unlikely to survive in the freshwater environment.
The gullet of a protozoan is an essential structure that plays a key role in feeding. It serves as a passageway for food particles to enter the cell, often leading to a food vacuole where digestion occurs. The gullet helps the protozoan to efficiently ingest and process nutrients from its surroundings. This process is crucial for the organism's survival and growth.
