I am designing an alien creature, an oxygen breather on an Earth-like planet. These creatures have a crest on their back that changes color according to the mood in which they are. That crest is a reminiscent of the sea creature they evolved from, a squid-like creature that changed color to camouflage and confuse predators.
I want to design a proper Latin name for them that has something to do with that crest. And I thought about "Crista coloratus". However, my Latin knowledge is limited to Google translate, and I am not sure if that really sounds like "colored crest" or another latin term should be more appropriate. The question is: Is Crista coloratus a proper latin name that makes sense for these creatures?
