型態描述

本物種在蓑海牛類裸鰓動物來說算是體型比較大的一種,其身長可達42 mm[4][5]。其伸展開來的身體有尖尖的尾部,而且背部滿佈被稱為「角突」的延伸。這些角突在不同的個體間大小不一。如同其他蓑海牛裸鰓動物物種那樣,本物種在吃掉刺胞動物後,能將牠們的刺絲胞儲存在自身背部的這些角突裡[6][5]。 The rhinophores are pointed and look like feathers. The oral tentacles are thin, cylindrical and longer than the rhinophores.[7] The coloration is variable and here's a description for the two main coloration which can be easily met underwater:

  • The classic coloration: the body is milky white to translucent, three reddish to purple continuous or dotted lines are running on both side and in the middle of the body, oral tentacles and rhinophores are whitish with a mauve to purple ring at the two third of their extremity, cerata are also whitish with a purple ring and with orange tip.
  • The purple coloration: whole body including cerata, rhinophores and oral tentacles are purple to mauve, without any continuous reddish line on the body but with just a darker ring at the two third of the cerata with clearest tips.

由於本物種的顏色多變,有作者認為這個物種很可能其實是一個复合种[8]

分佈及棲息地

本物種的模式產地位於紅海,但相信廣泛分佈於印度洋西太平洋熱帶亞熱帶溫帶的海域,北起日本以南[5]、東至夏威夷、南抵澳大利亞新南威爾士州[5]。本物種亦有見於香港西貢果洲群島[2]法屬波里尼西亞留尼汪马约特等地[5]的海域。此外, 本物種亦被發現已入侵地中海棲息[9]:114。 從觀察所見,本物種以水螅為食,而且棲息於有豐富水螅棲息的淺礁或海底岩坡[5]
