The Punky Blipoidius:
The male does all of the hunting, as the female has no tail and cannot swim. However the female does has a highly toxic sting coming down off of her mohawk which, if touched, will fry you to a crisp. Both male and female have a light coming off their heads which pulse with a unique bright light. These lights are used to attract mates and also to call for help in times of danger. However, they also light the way in the murky oceans for potential predators, meaning that the Punky Blibodius has a very short life span, averaging at around two months.
EDIT: Made minor alterations to the Punkies, and created a new background.
