''Oulactis muscosa'', also known as the sand anemone and speckled anemone, is a species of sea anemone in the family Actiniidae.〔 ==Description== This is a large, greenish-grey to off-white species, growing to 60-80 mm. It has up to one hundred〔 short, conical tentacles that are transparent to pale greenish to greyish-white, to pale brown, grouped into three rows. On the column, there are vertical rows of adhesive bumps (verrucae) that are relatively darker than the rest of the body. The tentacles also have horizontal black bands. The oral disk varies in colouration, and is sometimes red, green, black or white, and may have streaks of darker colour radiating outward from its mouth. This species can be recognized by gravel, bits of shell or coarse sand that it attaches between its tentacles.〔 ''Oulactis muscosa'' is closely related to ''Oulactis macmurrichi'' (the southern sand anemone), which shares the same distribution and habitat. ''Oulactis muscosa'' can be distinguished by the difference in colouration. The column of ''Oulactis macmurrichi'' is more reddish-brown, or green to light purple, and has light green tentacles. It is possible that the two are variants of the same species.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oulactis muscosa」の詳細全文を読む スポンサード リンク
