CharlieMarmorkrebs are the only known decapod crustaceans to reproduce by parthenogenesis. All individuals are female. Offspring are genetically identical to the parent, indicating they reproduce by apomixis (Martin et al. 2007). Because Marmorkrebs are genetically identical, easy to care for, and reproduce at high rates, they are a potential model organism, particularly for studying development (Alwes & Scholz 2006).
