Rhinomuraena quaesita has several characteristics that have lead experts to suggest that it should be placed in its own family — the Rhinomuraenidae; 
these include the positioning of its kidneys and most of its reproductive organs posterior to the anus (a unique condition that has not been reported in 
any other vertebrate).
