The first epipodial
tentacle was observed later after the onset of metamorphosis in Haliotis gigantea which was different from findings of this study for Haliotis mariae.
Similar tentacles occur posteriorly along the length of the epipodial
fold, the number depending on the size of the species and the individual.
4E); propodium distinctly demarcated; except for the anterior portion surrounded by thin epipodial
The papillae have neuroepithelial cells that are widely distributed on the surface of cephalic and epipodial
tentacles, and exhibit intense staining for GABA, along with their innervating nerve fibers.
External anatomy (Figs 5A, 6A): Head-foot with extensive dark brown to black pigmentation in living animal; cephalic tentacles more or less uniformly dark; blackish colour of neck lobes and epipodial
tentacles contrasting with whitish upper parts of foot.
This mechanism of shell overgrowth is also distinct from the growth of epipodial
(e.g., Anaspidea) or parapodial (e.g., Cephalaspidea) lobes in juveniles of other shelled opisthobranchs (Tardy, 1991).
tentacles were clipped from the respective parents of each family and mantle tissue samples were collected from the offspring for DNA isolation.
3 tentacles in anterior half; 6 or 7 large epipodial
tentacles on each side, with frequent smaller intermediary tentacles of varying size; an indistinct epipodial
sense organ present at base of larger epipodial
tentacles, none evident under neck lobes.
Tissue samples of mantle were cut from adults, and epipodial
tentacles from juveniles were removed with clippers.
On observation (day 63 after tagging), 8 animals had abnormal epipodial
tissue near the tagging site.
