Tritonioidea is a superfamily of sea slugs, nudibranchs, shell-less marine gastropod mollusks in the Suborder Cladobranchia.[1]
Tritonioidea was the only superfamily in the clade Dendronotida. The taxonomy of Bouchet & Rocroi for the clade Dendronotida was largely based on the classification established by Boss in 1982,[2] who in turn based his conclusions on the study by Odhner in 1968.[3]
The study of Wägele and Willan, published in 2000,[4] concluded that Dendronotida is monophyletic, although this monophyly had been questioned, based on the wide variety in sperm morphology, in a paper by Healy & Willan in 1991.[5]
