Just to tell you about a free d20 supplement available for free: the Book of beasts v3
http://www.dcrouzet.net/nbomisc/downloads/bookofbeasts_v3.pdf
This is a free netbook detailing many new creatures for the d20 system. The interesting thin is that there are several specifically science-fiction creatures. Yet, many animals and "vermin" could also be used in a traveller campaign. I think you should not miss it. It's free after all.
