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, despite the fact that this monophyly had been questioned, based on the wide variety in sperm
morphology, in a paper by Healy & Willan in 1991.

The term sperm is derived from the Greek word sperma and refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell...
