Classification provided by the World Register of Marine Species (WoRMS). [181221<\/a>]<\/p><\/div>Taxonomic note:<\/strong> This species has been traditionally confused with Berthella aurantiaca<\/em> because its external morphology is very similar, so much so that it is virtually impossible to distinguish them “de visu”. To differentiate these species is mandatory an study of the mandibular structure and the radular teeth. The radula of B. edwardsii<\/em> has numerous denticulate teeth (more than 150) in each semi-row and an elongated jaws and with smooth mandibular parts while the teeth of the radula of B. aurantiaca<\/em> are much less numerous (from 50 to 80 per semi-row) ) the mandibles are shorter and with the mandibular parts with denticles on the sides. Adult specimens can also be differentiated by the size of the inner shell, which in B.edwardsii<\/em> never exceeds 5.5mm (in specimens up to 60mm) since it stops growing when the animals reach circa 15mm in length (Jakov Prki\u0107, com.pers.), whereas in Berthella aurantiaca<\/em>\u00a0the shell is proportionally larger (Vayssi\u00e8re reported a 15mm shell in a 30mm specimen), as it protects the entire visceral mass.<\/p>\n
