Haminoea is a genus of medium-sized sea snails or bubble snails, marine opisthobranch gastropod molluscs in the family Haminoeidae, the haminoea bubble snails, part of the clade Cephalaspidea, the headshield slugs and bubble snails.
Systematics
Three different spellings (Haminoea, Haminea, Haminaea) were used for this genus over two hundred years. The ICZN finally made a decision that the correct spelling is Haminoea.
Oskars et al. (2019) restricted Haminoea to species from the Atlantic and eastern Pacific, and resurrected Haloa and Lamprohaminoea for Indo-Pacific species.
Description
Many species within this genus have green algae growing on their shells. The posterior tip of the headshield is bilobed, except in Haminoea elegans.
