The family Stichopodidae is represented in the Mediterranean Sea by the genus Parastichopus which includes two non-endemic species; Parastichopus tremulus (Gunnerus, 1767) and Parastichopus regalis (Cuvier, 1817). On the Algerian coast (southwestern Mediterranean Sea), two morphotypes of P. regalis were observed, one with dark spots on the dorsal surface and the other non-spotted. In total, 65 individuals of P. regalis were recorded from 22 stations along the Algerian coast during an oceanographic campaign. Twelve individuals (6 of each morphotype) were used for a comparative study of the morphological (including endoskeletal) characteristics. Table ossicles, the only ossicles of the body wall of the two morphotypes of P. regalis, are here compared with regard to the disk diameter of the tables and the total area of the surface of the disc. Statistical analysis did not show any significant differences between the spotted and the non-spotted morphotypes.
叶腕足科家族在地中海地区由 Parastichopus 属代表，其中包括两个非特有物种；Parastichopus tremulus (Gunnerus, 1767) 和 Parastichopus regalis (Cuvier, 1817)。在地中海的阿尔及利亚海岸（西南地中海），观察到两种 P. regalis 形态型，一种在背面有深色斑点，另一种没有斑点。在一次海洋学考察中，在阿尔及利亚沿海的 22 个站点共记录到 65 只 P. regalis 个体。从这 65 只个体中选取了 12 只（两种形态型各 6 只）进行形态（包括内骨骼）特征的比较研究。表骨片是 P. regalis 两种形态型体壁的唯一骨片，本文比较了表的盘径和盘表面总面积。统计分析显示，有斑点和无斑点形态型之间没有显著差异。
