Haliotis exigua : ウィキペディア英語版 | Haliotis exigua
''Haliotis exigua'' is a species of sea snail, a marine gastropod mollusk in the family Haliotidae, the abalones.〔( Index molluscorum maris japonici, conscriptus et tabulis iconum xvi illustratus a Guilielmo Dunker. p. 148 )〕 H. Pilsbry regarded ''Haliotis exigua'' as a juvenile of ''Haliotis diversicolor''.〔(H. Pilsbry (1895), Catalogue of the marine mollusks of Japan )〕 It is unclear whether this species deserves recognition.〔Geiger, D. L. 1998. Note on the identity of Haliotis clathrata Lichtenstein, 1794 (not Reeve, 1846). Molluscan Research 19: 157–159〕 ==Description== The size of the shell attains 21 mm. The flat oval shell has an irregular sculpture. It is slightly canaliculate in the middle. It is densely spirally striate and lirate, but obsoletely plicate. The apex is prominent. It has a dark coloration of gray-red. The inner surface is vividly iridescent.〔
