If I am correct, they are simple cell organisms, meaning they have no need of sexual reproduction. Instead, they bud, or asexually reproduce.

Different species of Amoeba show different relationship e.g. Entamoeba histolitica & Entamoeba coli are parasitic . Amoeba patauxant is comensal on Hydra .
hydra
Asexual and sexual reproduction, two methods of reproduction among animals, produce.
An ameoba is a microscopic, blob-like protist, while a hydra is like coral or sea anemones.
Hydras most commonly reproduce by budding in which as small juvenile, "polyp", grows on the stalk of it's body. When the polyp has matured, (or when the parent hydra dies), it will break off as a free swimming juvenile. In rare occasions, hydra reproduce sexually.
