Along with its sister group, the sea angels (Gymnosomata), the sea butterflies (Thecosomata) are included in the order Pteropoda. [3] The validity of the pteropod order is not universally accepted; it fell out of favour for a number of years, but recent molecular evidence suggests that the taxon should be revived. [14]

The monophyly of Pteropoda is the subject of a lengthy debate; they have even been considered as paraphyletic with respect to cephalopods. [1] Current consensus, guided by molecular studies, leans towards interpreting the group as monophyletic. [2]
As pelagic marine gastropods, Limacina swim by flapping their parapodia, inspiring the common name sea butterflies. Sea butterflies are part of the clade Thecosomata. Sea angels, similar to Limacina, are in the order Gymnosomata. Both of these orders are still referred to as "pteropods". Sea butterflies of the order Thecosomata have a shell ...

There are around 300 species of squid living in the ocean and they can range in size from less than an inch to the massive 50-foot-long giant squid. The strawberry squid ( Histioteuthis heteropsis ...
