Name
Janthinoidea Lamarck, 1812
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.[1]
Phylogeny
Molecular evidence supports a tree for Janthinoidea that shows the sequential development of traits for a neustonic life.[1] 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.[1]
