He observed that the large particles accumulated on the left epipodium (neck lobe) and were then transported anteriorly by the action of cilia on the left anterior edge of the mantle (Fig.
McLean (1981, 1982), however, identified certain lineages within these subfamilies that shared distinctive features of the shell, radula and epipodium.
It was resolved to some extent by McLean's synonymy which recognized 13 species from a previous total of 58 names based on characters of the shells, epipodium, and in some cases radulae, complemented by data on their geographic distributions.
The edible part of abalone can be differentiated into 3 parts: the columellar region (adductor muscle), the epipodium, and the petal sole (Olley & Thrower 1977).
Cephalic lappets present but small and not extending across forehead; right postocular peduncle well developed, similar in size to eyestalk or perhaps larger; right subocular tentacle not evident; neck lobes similar, each with 5 or 6 tentacles of varying size; epipodium posterior to neck lobes with 4 or 5 tentacles of varying sizes on each side, with an epipodial sense organ faintly discernable at base of larger ones.
In the inflorescence branches, the internode length is variable; with the epipodium being the internode showing the main variations.
External anatomy (Figs 5B, 6E): Body white with pale brownish maculations on sides of foot and underside of epipodium, snout heavily marked (transversely) with dark brown to black.
In Andropogoneae, the shBr consists generally of a short hypopodium (virtual); a prophyll whose axillary bud forms a sessile spikelet; a long epipodium (pedicel); and a pedicellate, generally more reduced spikelet (Vegetti, 1994, 1999).
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 color in H.
