Abstract

The form of the globiferous pedicellariae from Psammechinus miliaris is described. The valve ossicle resembles that of Parechinus in its triangular valve shape and open blade form, contrasting with Echinus in these features. The present study indicates that the relationship of the valve nerve pathway to the skeletal ossicle is related to the form of the distal blade. It is proposed that subterminal teeth or a tubular blade may be alternative structural devices for strengthening the venom tooth during venom injection.

摘要

描述了来自粒屑海胆的球根状叉棘的形态。瓣状小骨在其三角形瓣状形状和开放叶片形式上类似于猬团海胆，在这些特征上与海胆属形成对比。本研究表明，瓣状神经通路与骨骼小骨的关系与远端叶片的形态有关。有人提出，亚末端齿或管状叶片可能是在毒液注射期间加强毒牙的替代结构装置。
