Although Nimare have developed to be bipedal over centuries, due to also laying claim to homes on land and interacting with the surface more, they have ever retained the ability to turn into their leg-less mer form. Since for this transformation, their legs and fins merge to form a long tail or tentacles respectively, their rank cannot always be determined by the size of it alone - although it is still true that most betas and alphas will have bigger or longer tails than an omega.
