Shell description

All ''Bulla'' species have large, ovate, external shells, which are large enough to accommodate the whole snail when retracted. All species have rather similarly shaped shells, which have a deep, narrow umbilicus at the apex. No operculum is seen. The smooth shell of ''Bulla'' spp. is ovate and expanded, with a deep, sunken involute top. Since little difference exists between the shells and in the morphology of the radular teeth, some uncertainty remains about the exact taxonomy of the species in ''Bulla''.

Anatomy of the soft parts

The gizzard of ''Bulla'' is rather different from that of other herbivorous groups. It has three large, corneous crushing plates and ancillary corneous spines, instead of just grinding plates. These crawling snails show prominent, frilled, or lobed parapodia. ''Bulla'' species have a soft

radula The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food ...

Taxonomy

This family seems to have evolved separately in an early stage of the evolutionary history of the opisthobranchs. For a fuller treatment of the whole group see Cephalaspidea. ''Bulla'', ''Haminoea'', and ''Smaragdinella'' form the well-defined

group Bulloidea, according to the 1996 phylogenetic analysis of Paula M. Mikkelsen, but according to Dr. Bill Rudman and others, differences in the alimentary canal and reproductive system still put ''Haminoea'' and ''Smaragdinella'' into the separate superfamily Haminoeidea. Historically, since the 18th century and even in the 20th century, the genus name ''Bulla'' has been used for a great number of bubble-shelled species that belonged to the order Cephalapsidea. From the mid-20th century, authors began to restrict species to the genus ''Bulla'' in its current meaning. Misidentifications were still numerous through high levels of intraspecific variability in the shell,
