Polymorphic. Polymorphisms
refer to spasmodic genetic variation within the same species of an organism resulting in varying forms of the species. Polymorphic viruses, mutate at faster rates hence the virus
population is subject to high rates of turnovers. The high divergence of various
species, such as influenza, is as a result of 0.01 mutations per nucleotide site
per year.
Binary fission occurs in single-celled organisms only and mitosis is just one cell dividing into two (eukaroytic cells)

They find shells that other crabs have left behind and use them
