Anthopleura sola

Anthopleura sola and Anthopleura elegantissima have the same morphology (body form), but A. sola doesn’t reproduce by longitudinal fission (splitting in two). They live alone, and are significantly larger. Other evidence distinguishing them as another species, is they have distinctly different northern habitation boundaries and genetic variations which together confirm they are different species and therefore, do not reproduce with each other.
