Bulla

Bulla ampulla, copyright Erwin Köhler.

Belongs within: Cephalaspidea.

Bulla is a genus of relatively large bubble snails with a well-developed shell into which the animal is able to withdraw completely.

Characters (from Malaquias & Reid 2008): Shell ovoid, solid, mottled in drab colours. Spire involute. Aperture slightly longer than shell height. Cephalic shield produced antero-laterally, forming pair of siphon-like tentacles. Penis invaginable, formed by a long duct continuous with coiled prostate, ending in a narrow terminal blind caecum; all structures enclosed in thick muscular sheath, contiguous with a long tubular vestibular area; retractor muscle attached to proximal area of penial sheath. Anterior gonoduct slightly helicoid; fertilization chamber rounded, located at mid-length; seminal receptacle placed antero-ventrally, attached to wall of common genital duct. Rachidian tooth broad, denticulate, with central cusp usually smaller. Large gap between rachidian and laterals. Inner lateral claw-shaped, usually symmetrical with major central cusp and 3–4 lateral cusps on either side. Outer lateral with smooth vertical internal edge and denticulate convex outer edge with 4–10 cusps; base with denticle. Second outer lateral teeth reduced, plate-like. Gizzard plates uncalcified, smooth, with longitudinal keel.

The Retusidae, canoe shells, are a family of infaunal cephalaspid gastropods characterised by the lack of a radula. Instead, their diet of forams and minute molluscs is processed by gizzard plates.

Haminoeidae

Atys naucum, copyright Erwin Köhler.

Belongs within: Cephalaspidea.

The Haminoeidae are a group of bubble snails that primarily graze on algal tissue and/or diatoms; the shell may be partially or entirely covered by lateral outgrowths of the mantle. The shell may be thin and fragile as in the genus Haminoea, or relatively solid and thick as in Atys.

Characters (from Too et al. 2014): Shell usually thin, translucent, fragile, occasionally solid and thick; varying from bulloid to cylindrical-elongate; spiral grooves may be present at ends or covering entire shell. Mantle and other body parts usually dull and cryptically coloured, occasionally colourful or capable of changing colour to suit environment. Muscular buccal bulb present containing chitinous jaws and radula formed by variably-shaped central tooth plus hook-shaped lateral teeth. Fizzard present with three plates containing pointed rods.

Thecosomata

The Thecosomata, sea butterflies, are a group of pelagic marine gastropods that have the foot modified into a pair of wing-like parapodia used in swimming. Most Thecosomata retain a calcareous shell though the shell is demineralised or lost in some subgroups. Loss of the adult shell is found in the Cymbuliidae and Desmopterus within the Cymbulioidea.

The Philinidae are a group of headshield slugs with a delicate internal shell and a dorsal aspect divided between the four regions of head, visceral mass and lateral parapodial lobes. They commonly live infaunally in fine sediments; a smaller number of species live epifaunally.

Gymnosomata

Hunting Clione limacina, copyright Alexander Semenov.

Belongs within: Euopisthobranchia.

The Gymnosomata are a group of shell-less, pelagic marine gastropods in which the foot has been modified into a pair of large parapodia used for swimming. The lateral position of the parapodia well behind the head has lead to their vernacular name of 'sea angels'.

Systellommatophora

Warty slug Onchidium verruculatum, copyright Cory Pittman.

Belongs within: Heterobranchia.

The Systellommatophora are a group of slug-like gastropods including the marine Onchidiidae and the terrestrial Veronicelloidea. Members of this group have two pairs of contractile tentacles on the head, with the eyes at the tip of the upper pair, and have the anus and renal opening at the posterior end of the body (Burch & Pearce 1990). The dorsum is covered by a leathery covering, the notum. The Veronicelloidea are divided between the herbivorous Veronicellidae and the carnivorous Rathouisiidae, the latter family being characterised by narrow dagger-like radular teeth (Stanisic et al. 2010).

Scaphopoda

Siphonodentalium lobatum, copyright Natural History Museum Rotterdam.

Belongs within: Rostroconchia.
Contains: Cadulus, Dentalium.

The Scaphopoda, tusk shells, are a group of benthic molluscs with a tubular shell that live buried in the sediment, feeding on micro-organisms. In members of the Dentaliida, the shell generally tapers evenly whereas Gadilida commonly have the shell constricted toward the mouth (Ludbrook 1960). Two pairs of dorsoventral muscles are present in Dentaliida whereas a single pair is found in Gadilida (Steiner 1996). Dentaliida have an encircling sheath around the foot that is expanded laterally and interrupted dorsally (Ludbrook 1960) and the pedal muscles are associated with the body wall along the entire length of the body (Steiner 1996). Gadilida have the foot simple and vermiform, or distally expanded into a symmetrical disc (Ludbrook 1960). The pedal muscles are separated from the integument in the distal part of the foot in Entalina and are entirely separate from the body wall in Gadilimorpha; instead, they occupy a central position in the body and attach to the dorsoventral muscles at the diaphragm between intestinal sinus and perianal sinus (Steiner 1996). The disc of the foot has a digitate periphery in the genus Entalina; the shell of Entalina is Dentalium-like and strongly ribbed (Ludbrook 1960).

Characters (from Ludbrook 1960): Marine, bilaterally symmetrical mollusks protected by an external elongate, tubular, tapering, calcareous shell, open at both ends and generally somewhat curved. Concave side of shell dorsal, convex side ventral; aperture or anterior opening larger, apex or posterior opening simple or variously slit or notched, some forms with terminal pipe. Shell substance of three distinct layers. Shell secreted by mantle of same shape, larger (anterior) opening of which is contracted by muscular thickening of mantle, giving egress to long conical foot; smaller (posterior) opening serving as outlet for organic waste and genital products. Mouth furnished with radula, borne on cylindrical snout and surrounded by rosette of lobes; a cluster of threadlike, distally enlarged appendages known as “captacula” springing from its base. No eyes or tentacles; otocysts present. Liver 2-lobed, symmetrical; gut strongly convoluted, anus ventral and somewhat anterior, kidney openings near it. Heart rudimentary; no gills, respiration performed by general integument. Nervous system with well-developed ganglia united by commissures. Gonad simple, sexes separate, reproduction without copulation.
