Janthinoidea is a superfamily of sea snails containing wentletraps (Epitoniidae) and surfing snails (Janthinidae). It includes species that have tethered egg masses, some of which are used for flotation.
Molecular evidence supports a tree for Janthinoidea that shows the sequential development of traits for a neustonic life. The wentletraps (Epitoniidae) have tethered egg masses that started to be used for flotation in Recluzia and then totally divorce from its original function for the ovoviviparous Janthina janthina.
Janthinoidea includes the following families, genera, and species.
