Trill

Trill: You appear as a standard Terran, but your hair is generally darker and your skin ranges from pink to olive. However, dark brown spots — that are unique, much like fingerprints on Terrans — run from your head, down your neck and to the back of the heels of your feet.
What separates you from other Trill, is that you share a symbiotic relationship with a worm-like creature. You share some knowledge and traits with this symbiont.

 
You can choose one skill, this will always be a class skill. Further, your result cap with these skills is increases by 5 (maximum 60). These are based upon the symbiont’s past key progression. While this skill is usually revolves around Science or Medicine, it's certainly not limited to those.
The skill chosen above gains four bonus skill points at Career Level 1, and 1 additional skill point for each Career Level gained thereafter.
Based on your symbiont's past you gain 1 acquaintance-grade contact. This contact improves by 1 grade at Career Levels 6, 12, and 18.
Semi-hominid. Attempts to treat you with non-Trill medicine suffer a -8 penalty. You suffer an -4 penalty on all attempts to disguise yourself or blend in with non-Trill.
You gain access to Trill racial feats.
You suffer a -4 penalty during transporter mishaps, or whenever a check is required to see if you were properly transported. (The symbionts don't handle the transporters very well.)
