siphon

a structure occurring in molluscs through which water is drawn in and out of the mantle cavity and which in some is used to create a jet to propel the animal through the water.

He mentioned as main shell differences in Bulliinae the lack of a recurved siphonal channel with a carina on the dorsal side of the fasciole, and the reduced ornamentation.
Nucella trancosana is a low-spired thick-shelled species with strong apertural teeth that extend into the aperture as ribs, a short siphonal canal, and numerous spiral cords (up to 24) on the body whorl.
APLEN Aperture length, the length from the suture of the aperture to the tip of the siphonal canal.
Sipho thick basally narrower distally; siphonal capsule very weakly hook shaped with opposite arm distinctly large broader cylindrical while adjacent arm very small narrow; median lobe narrow apically slightly longer than parameres; trabes apically bifurcated.
Description: Shell fusiform with truncated base; b/l 0.35-0.38, a/l 0.38-0.41; whorls strongly convex with narrow angular shoulder, and undulant, fairly deep suture, base of last whorl without a waist-like constriction; rostrum narrow, without a fasciole; aperture narrowly elliptical; siphonal canal strongly contracted but slightly expanded terminally, end truncate, oblique in dorsal view, not notched.
bugensis in the anatomy of the siphonal region, but it remains to be seen if this character state endures future scrutiny, especially among populations occurring within the native range of Dreissena spp.
Not included in this length-frequency analysis were 7.8% of OC, 9.0% of ES, and 6.3% of VB whelk landed on-board with broken siphonal canals, which were largely the result of culling practices on board commercial vessels (personal experience) and result in inaccurate length measurements.
deltoidea individuals used in the trials ranged in size from 19.1 mm siphonal length (SL; the distance from the apex to the tip of the siphonal canal) to 44.8 mm SL (mean [+ or -] 1 SE = 33.0 [+ or -]1.1 mm SL).
The shell lengths were taken from the apex to the distal end of the siphonal canal (Fig.
The elongated and tubular shape of the shell, with siphonal and pedal gapes, facilitates penetration into the substrate, whereas ejection of water through the pedal gape liquefies the surrounding substrate (Stanley 1975, Checa & Cadee 1997).
