长棘星螺(学名:Guildfordia yoka),又名長刺螺[3],是一種深海海螺物種,屬於海洋腹足綱軟體動物蝾螺科刺螺屬的一個物種[4][5]

分佈與棲息地[编辑]

這種熱帶的海洋生物物種棲息於西太平洋的日本和菲律賓對開海域,見於水深200、500米(660、1,640英尺)的海洋[6]; 也見於中国大陆台湾[4]。常栖息在潮下带[4]

型態描述[编辑]

The size of the shell varies between 70、105 mm(2.8、4.1英寸). The color pattern of the shell varies from very light brownish to purple-brown. Some specimens contain only 6 whorls instead of 7 as in the holotype. The upper whorls are smooth, then follows the body whorl with scarcely 2 rows of granules, instead of 7 or 8. Towards the keel it has very irregular radiating ribs, which leave however a nearly smooth zone above the keel, with only a few spiral striae.

The base of the shell is less convex than the upper part. Some specimens lack the rose-coloured line round the umbilical callosity. The aperture is oval, thick, with the nucleus in the external lower corner. The outer surface is slightly rugose, by irregular wrinkles, almost parallel with the basal margin of the operculum. The nucleus is marked by an olive spot.[2]

Biology[编辑]

Embryos of Guildfordia yoka develop into free-swimming planktonic larvae with several bands of cilia (trocophore). Later they develop into juvenile veligers, finally into fully grown adults.[6]
