小塔螺科

肠纽目的一科软体动物

小塔螺科[2]（學名：Pyramidellidae），亦作尖塔螺科或簡單只叫塔螺科，是軟體動物門腹足綱下的一個科。舊屬腸紐目（Heterostropha，又譯異旋目）[2]，成員主要是營寄生生活的小型海螺。

小塔螺科的物種分佈於整個世界，有超過六千個不同的物種，合組成超過350個屬與亞屬[3]。由於本科物種皆屬於微小貝，相關研究少，物種間支序親緣關係（英语：phylogenetic）並不十分清楚，大眾對於各物種的歸屬也沒有共識。舉例說：單單是 Schander (1999) 就列出了超過300個屬級以上的分類單元命名，並將這些分類單元整理[4]。由於近年本科在世界各地各個屬的分類未再有可一般化的修訂，這個科內各個分類單元仍然保持是多系群，也就是說這些分類的混亂還有一段時間。然而，從整個科來看仍然是個單系群[5]。

分類

编辑

本科物種主要分為11個亞科（Ponder & Lindberg 1997）[6]。An alternative interpretation is that the family Pyramidellidae is but one of six families within the superfamily Pyramidelloidea (Schander, van Aartsen & Corgan 1999).[7] 當中有不少罕見或不常紀錄的物種。

本科之下的亞科在不同年代刊行的分類學文獻都有所不同，當中最為普遍的分類是2005年的布歇特和洛克羅伊的腹足類分類[8]。以下詳列自1997年以來多個分類間的差異。

1997年分類

2005年分類

编辑

在2005年《布歇特和洛克羅伊的腹足類分類》，原來小塔螺總科之下的各科均被降級成為新的小塔螺科的亞科；而各科之下的亞科亦變成了各個亞科之下的族。這些變更總結如下[8]：

    • Tribe Eulimellini Saurin, 1958 - formerly subfamily Eulimellinae
  • Pyramidellidae incertae sedis

往後分類的轉變

编辑

2010年，本科得到確認為單系群[9]。

2017年，棲息於中南太平洋深海的塔螺總科新屬Helodiamea屬 Peñas & Rolán, 2017得到確認[10]。

截至2018年7月9日 (2018-07-09)，WoRMS紀錄小塔螺科包括下列各亞科與族[11]：

  • Subfamily Cyclostremellinae D. R. Moore, 1966
  • Subfamily Odostomiinae Pelseneer, 1928
    • Tribe Chrysallidini Saurin, 1958
    • Tribe Cyclostremellini D. R. Moore, 1966

分佈

编辑

本物種有世界性分佈，但當中不少物種都只在相當細小範圍內分佈。在佛得角的各物種均為當地的特有種[13]。

型態描述

编辑

The length of the slender, elongated (turreted or conical) shells varies between 0.5 mm and 3.5 cm, but most species in the family have shells which are smaller than 13 mm.

The texture of these shells is smooth or sculptured in various forms such as ribs and spirals. Their color is mostly white, cream or yellowish, sometimes with red or brown lines.

The shell of these snails has a blunt, heterostrophic (i.e. whorls appear to be coiled in the opposite direction to those of the teleoconch) protoconch, which is often pointed sideways or wrapped up. The teleoconch is dextrally coiled, but the larval shells are sinistral. This results in a sinistrally coiled protoconch.

The columella has usually one, but sometimes several, spiral folds. The aperture is closed by an operculum.

The operculum is ovoid and paucispiral, with the apex anterior, a thread-like arcuate ridge on the proximal side, the inner margin notched in harmony with the plaits of the pillar when prominent.

習性

编辑

The Pyramidellidae are ectoparasites, feeding mainly on other molluscs and on annelid worms, but some are known to feed on peanut worms and crustaceans.[14][15] A few species in the family Pyramidellidae, such as Otopleura mitralis, are symbiotic with sea anemones, such as Neoaiptasia morbilla.[16]

They do not have a radula. Instead their long proboscis is used to pierce the skin of its prey and suck up its fluids and soft tissues. The eyes on the grooved tentacles are situated toward the base of the tentacles. These tentacles have a concave surface. Between the head and the propodium (the foremost division of the foot), a lobed process called the mentum (= thin projection) is visible. This mentum is slightly indented in midline.

These gastropods are hermaphrodites, laying eggs in jelly-like masses on the shell of its host. Some species have spermatophores.[4][17][18]

語源

编辑

本科的學名源於金字塔的英語pyramid，而這亦是這些物種普遍的外型[19]。 準確點說：這些物種都呈正圓錐體的模樣[20]，又或是正多邊形的錐體[21]。
