东港卷管螺科(学名:Cochlespiridae)是一个捕食性海螺的分类单元,是芋螺总科之下的一个海洋腹足纲软体动物的一个科[1]。
本科物种在型态学上与其他科物种的分野并不明显,而且其螺壳的型态与分子生物学的数据并不一致。各属所属的物种很可能还要再调整
本科物种主要由原来卷管螺科东港卷管螺亚科(Cochlespirinae),再加入新的属升格而成。升格后的东港卷管螺科不设亚科级分类单元。
本科物种的体型一般都在20到30 mm左右;Nihonia maxima的体型比较大,最长可达128 mm,Aforia magnifica的螺壳甚至可达150 mm长。螺壳呈卷管状,纺锤形,有长而尖的壳尖。 Axial sculpture is absent or feebly developed. The aperture is ovate. The columellar margin is smoot. The outer lip has a narrow profound anal sinus on the subsutural ramp。与大多数芋螺总科物种不同的是:本科物种的虹管沟通常非常直、窄和狭长。The螺厣has a terminal nucleus.
The foot of the animal is truncated anteriorly, obtuse posteriorly. The eyes are located externally near the base of cylindrical tentacles. 齿舌的齿式是1-0-R-0-1[1]。 The duplex radular teeth are nonhypodermic.
