Jadzia Dax, more alien-looking alien edition! Amphibious Trill: It Just Makes Sense. (Also, I already have a soft spot for salamander people.)

her belly is translucent, like a tadpole’s! You can see Dax curled up in there. Honestly, if you have a character with a symbiotic creature in their body and you don’t make it at least a little weird, what are you even doing?
