Vinean Physiology
Vineans are of pale blue skin, but otherwise very closely resemble humans. No reasons are given in-universe for this extreme similarity of two species that evolved millions of years (and two galaxies) apart, and neither is this matter ever raised in the novels. However, it is understood throughout the series that Vineans cannot sunburn because their pale blue skin is more resilient than that of humans.
It is also indicated that some medicine will not have the same effect on Vineans as humans.

Famous quotes containing the word physiology:
“If church prelates, past or present, had even an inkling of physiology they’d realise that what they term this inner ugliness creates and nourishes the hearing ear, the seeing eye, the active mind, and energetic body of man and woman, in the same way that dirt and dung at the roots give the plant its delicate leaves and the full-blown rose.”
—Sean O’Casey (1884–1964)
