Summary
From the book jacket
Not precisely, Doctor. On  the 'teddy bears' are alive and they have six-inch fangs
- Spock to McCoy, 

It's a menagerie out there…
From the Klingon targ to the Ceti Alpha eel, the galaxy plays hosts to lifeforms that strain the imagination of even Starfleet's finest zoologists. They won't strain yours, though, because Creatures gives you the complete readout on dozens of aliens beasts for your Star Trek RPG series. You'll know what to do when the Tarkassian razor charge, and you'll learn the best way to avoid mugato bites. In fact, after reading this book, alien monsters will probably cease to give you any tribble at all…

Creatures includes :
 Creatures from all eras of STAR TREK, including guidelines for incorporating them into your series.
 More than 60 creature descriptions, from the Aldebaran serpent to the Yridian yak, complete with full STAR TREK RPG statistics and rules.
 Detailed and expanded rules for creature design.
