Foraminiferans and radiolarians are distinguished by their unique, intricate shells made of calcium carbonate (foraminiferans) or silica (radiolarians). These structures serve as protective coverings and help with buoyancy and capturing food, setting them apart from other amoebae that lack such specialized structures. Additionally, foraminiferans and radiolarians are marine organisms found in ocean environments, unlike many other amoebae that inhabit terrestrial or freshwater habitats.

Some amoebae can be pathogenic to humans, with the most notable example being Entamoeba histolytica, which causes amoebic dysentery. Other species, such as Naegleria fowleri, can lead to severe brain infections. However, many amoebae are harmless and play important roles in the ecosystem as decomposers and in nutrient cycling. Overall, while not all amoebae are pathogenic, certain species can pose significant health risks.
Amoebae are single-celled organisms, and there are ways to kill them such as through harsh environmental conditions, chemicals, or medications specifically targeted at them. However, it's essential to consider the potential effects on the surrounding environment and other organisms when attempting to control amoebae populations.
There can be other things in the sample beside bacteria that don't grow on this kind of plate like viruses, molds or larger microbes like amoebae. So the sample isn't necessarily sterile.
Sarcodines are unicellular protists that move and capture food using pseudopods, which are temporary extensions of their cell membrane. This distinguishes them from other protists that may use cilia or flagella for movement and feeding. Sarcodines also exhibit diverse shapes and structures, such as amoebas and foraminiferans.

Amoebae are heterotrophic, meaning they must eat other organisms to survive.
plantsAmoebas eat bacteria, algae and other protozoa.

Some amoebae are predatory and live by consuming bacteria and other protists. Some are detritivores and eat dead organic material.

Radiolaria can be defined as amoeboid protists which produce mineral skeletons. The skeletons, usually of silica have a central capsule. Radiolaria are heterotrophs who eat other things, but also may include protest algae as endosymbionts.
Amoeba (sometimes amœba or ameba, plural amoebae or amoebas) is a genus of Protozoa consisting of shapeless unicellular organisms.The cell's organelles and cytoplasm are enclosed by a cell membrane; it obtains its food throughphagocytosis. This makes amoebae heterotrophs. Amoebae have a single large tubular pseudopod at the anterior end, and several secondary ones branching to the sides. The most famous species,Amoeba proteus, averages about 220-740 μm in length, while in motion [6] making it a giant among amoeboids.[7] A few amoeboids belonging to different genera can grow larger, however, such as Gromia, Pelomyxa, and Chaos.Amoebae's most recognizable features include one or more nuclei and a simple contractile vacuole to maintain osmotic equilibrium. Food enveloped by the amoeba is stored and digested in vacuoles. Amoebae, like other unicellular eukaryotic organisms, reproduce asexually viamitosis and cytokinesis, not to be confused with binary fission, which is how prokaryotes (bacteria) reproduce. In cases where the amoeba are forcibly divided, the portion that retains the nucleus will survive and form a new cell and cytoplasm, while the other portion dies. Amoebae also have no definite shape.
