Dolfini are two legged, fish-like aliens that originated from prehistoric aquatic creatures. Individuals have grey, smooth skin, along with one eye set on top of the head, though this eye is only capable of distinguishing the difference between day and night. Their true use of sight is echolocation ultrasound, similar to that used by Bats or Dolphins (hence their name). Dolfini have a diet similar to aquatic animals as well, often eating fish and seaweed as their main source of food.
