Tritonioidea

Tritonioidea is a superfamily of small sea slugs, nudibranchs, shell-less marine gastropod mollusks in the clade Dendronotida.

Tritonioidea is 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, who in turn based his conclusions on the study by Odhner in 1968.

The study of Wägele and Willan, published in 2000, 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.
