variations in the development of the epipodium in the different species
epipodium determines whether inflorescences are looser or denser.
6D): General body colour yellowish white, epipodium paler with a few scattered black blotches, also on sides of the foot; cephalic tentacles, forehead and snout usually with grey-brown to black pigmentation.
Notes on the soft parts of Trochus infundibulum Watson with an account of a remarkable sexual modification of the epipodium, hitherto undescribed in Mollusca.
The internode growth from the inflorescence branch axes (except the epipodium
) affects the inflorescence shape, especially in the manner in which branches group in the distal portion of an inflorescence branch with a developed epipodium
; these groups can be simply described as a contracted head or glomerulous (e.g.
Shell length was measured (to the nearest millimeter) and animals were evaluated for cuts or abrasions to the foot or epipodium
, shell chips, and presence of boring sponges.
Progressive signs of disease include pedal atrophy, diminished responsiveness to tactile stimuli, discoloration of the epipodium
, and a loss of ability to maintain adhesion to rocky substratum.
Future studies should focus on the cause of the variation of epipodium

The removal of an epipodium
