Habitat. Slime molds live in somewhat variable habitats all over the world. Generally slime molds live in damp areas of vegetation. They live under rotting logs and damp leaves. Some of the other habitats that slime molds will inhabit include water such as tropical fish tanks.
Slime molds. Slime molds are organisms in two taxonomic groups, the cellular slime molds (Phylum Acrasiomycota) and the plasmodial slime molds (Phylum Myxomycota). Organisms in both groups are eukaryotic (meaning that their cells have nuclei) and are fungus-like in appearance during part of their life cycle.
