Callistonian

Callistonians are the native sapient inhabitants of Jupiter's satellite Callisto.

Biology
Callistonians are 8 ft tall (~ 2.4 meters) bipeds with scaly reptilian skin and a mane of dense white fur protecting their heads, chests and backs. They have two pairs of tentacular arms and seem to have evolved as arboreal creatures on the towering trees of their homeworld.

Callistonians are oviparous and lay their eggs in natural warm springs. They are born as tadpole-like larvae.

Culture and society
Callistonians are a peaceful species which build cities out of massive blocks (facilitated by their homeworld's low gravity) and wear clothes woven from vegetable matter.
