Lossil

Lossils are large, carnivorous, whale-like creatures native to the planet Untra.

Appearance
Lossils can reach up 15 feet long in rare cases, although they are more commonly around 10 meters long. They are mostly blue-grey, however, during the mating season the males will turn to more vibrant colours. Lossils have 4 large fins along their long, thick body, and they lack any distinct tail. They have a pointed snout with many sharp teeth and large, bulging eyes.

Behaviour
Lossils are carnivorous and social creatures. Families will sometimes reconvene at specific times during the year. Scientists are unsure of how they know when to go where, but it appears to be merely social. As scientists know that males change colour during mating season, scientists also are beginning to believe that the Lossils's mating colour depends on what foods they eat, and therefore it may display more than a male's favourite colour (Such as how healthy the male is). This would allow females to make more informed choices of which males to mate with and ensure the survival of the species for a longer period of time.

Habitat
Lossils live all across Untra, including at the frozen poles, where they appear to have their meeting conventions. New radio technology has managed to deter them from coming near the Untralan cities, which protects the Untralans and their homes from attack and destruction.
