Nichibotsu, the Sunset Eel people of the planet Inudatius

My Nichibotsu People for a Star Trek alien concept. Named after the Sunset, the Nichibotsu Eel people of the planet Inudatius resemble Earth's Dragon Eel to an uncanny degree. They are asexual, capable of changing gender at a moment's notice under specific circumstances.
