It got me thinking about how in most Traveller games I've been a player in the worlds we visited seemed to be either very Earth like, with green clorophyle based flora, or very arid/desert like.  When I run games, I like to have very alien planets.  I really liked the graphic book Expedition by Barlow, thre are some far out critters there...

Ever eat seaweed? It is sometimes purple. Also there are purple velvet
