Abstract

Family Pterasteridae is almost exclusively from deep water and is of worldwide distribution (Clark and Downey, 1992), and is composed of eight genera: Amembranaster Golotsvan, 1998, Benthaster Sladen, 1882, Calyptraster Sladen, 1882, Diplopteraster Verrill, 1880, Euretaster Fisher, 1940, Hymenaster Thomson, 1873, Hymenasterides Fisher, 1911, and Pteraster Müller & Troschel, 1842 (Mah and Hansson, 2015). Species of this family usually have stout thick body, inflated dorsal surface, and supra­ dorsal membrane forming a cover over dorsal surface. They have a hole in the middle of disc called osculum, which can be used to expel mucus for defending against predators, like many other members of the order Velati­ da (Mah, 2010). Genus Pteraster comprises 46 species of which P. tesselatus Ives, 1888 distributed Korea, Ja­ pan, and North Pacific Ocean have been reported in Ko­ rean fauna (Shin, 2010).
标题东海海星属新记录(星总纲:帆形目:翼星科)
Pterasteridae科几乎全部来自深水,分布于全球(Clark and Downey, 1992),由8个属组成:Amembranaster Golotsvan, 1998年,Benthaster Sladen, 1882年,Calyptraster Sladen, 1882年,Diplopteraster Verrill, 1880年,Euretaster Fisher, 1940年,Hymenaster Thomson, 1873年,Hymenasterides Fisher, 1911年,Pteraster m ller & Troschel, 1842年(Mah and Hansson, 2015)。本科的种类通常有粗壮厚实的身体,膨大的背表面,背上膜形成覆盖在背表面上。它们在圆盘的中间有一个孔,叫做隐骨,可以用来排出粘液来防御捕食者,就像许多其他的Velati - da目成员一样(Mah, 2010)。Pteraster属包括46种,其中P. tesselatus Ives, 1888分布于韩国、Ja - pan和北太平洋,已在Ko - rean区系中报道(Shin, 2010)。
