摘要

棘头类动物的可伸缩喙上装有钩,用于附着在最终寄主的肠道上。在它们的进化史上,棘头类动物已经发展出各种各样的方法来最大限度地锚定宿主的肠道,避免移位。鱼钩在长鼻的纵轴上的大小和形状、质地、结构和硬度以及它们对营养吸收的贡献各不相同。钩子的化学成分也各不相同,尤其是钙、磷和硫,这有助于它们的硬度。钩根是最重要的锚定他们的角质层和角质层的吻。根的大小和形状各不相同,通常是简单的,指向后方,但通常有前柄,也可能退化或缺失,特别是在后方。树根的核心层通常与钩子的核心层是连续的。钩子在家庭中经常(但不总是)保持类似的模式。由于钩的描述不一致和不充分,特别是在线条图中,在不同的棘头类动物群体中,我们决定提供我们多年来研究的许多物种中形态学和解剖学变异的最大分类。因此,我们报告了13科30种棘头类动物鱼钩的扫描电镜,试图阐明棘头类动物科的模式和趋势特征。

SEM Study of Hooks in the Acanthocephala with Emphasis on Structural-Functional Relationships
The retractable proboscis of acanthocephalans is equipped with hooks for attachment to the intestine of the definitive host. Throughout their evolutionary history, acanthocephalans have developed a variety of ways to maximize their anchoring to host gut and to avoid dislodgement. Hooks vary in their size and shape along the longitudinal axis of the proboscis, texture, structure, and hardness as well as in their contribution to the absorption of nutrients. Hooks also vary in their chemical composition, especially calcium, phosphorus, and sulfur, contributing to their hardness. Hook roots are paramount in anchoring them to the cuticular and subcuticular layers of the proboscis. Roots vary in size and shape and are often simple and directed posteriorly but often have anterior manubria or may be vestigial or absent especially posteriorly. The core layer of roots is usually continuous with that of the hook. Hooks often, but not always, maintain a similar pattern in families. Because of the inconsistencies and inadequacies in the description of hooks, especially in line drawings, in various groups of acanthocephalans, we have decided to provide the largest assortment of morphological and anatomical variabilities among the many species that we have studied over the years. We are, thus, reporting the SEM of hooks of 30 selected species of acanthocephalans in 13 families in an attempt to elucidate patterns and trends characteristic of acanthocephalan families.
