Types of dimorphism (having two body types) include:

• Sexual dimorphism is differences in the body appearance of a species based on sex.

• Nuclear dimorphism is when a cell's nuclear apparatus is composed of two structurally and functionally differentiated types of nuclei.

• Phenotypic dimorphism is switching between two cell-types. For example the fungus Candida albicans infects host tissue by switching from its usual unicellular yeast-like form into an invasive, multicellular filamentous form.
