Zeffliffl

Zeffliffl, the fourth planet orbiting Markbee's Star, is home to the seaweed-like aliens also known as Zeffliffl. They inhabit the shallow seas surrounding the smaller southern continent of the planet, and must spray themselves with seawater when spending time on land. The Zeffliffl exist in close groups of several individuals, and their bodies will automatically reject any outsider who attempts to join this group. [TCS]
