Martian (The Blue Earthman)

The Martians are a sapient species of gigantic creatures which invaded Earth in a future so distant that the sun had already engulfed Mercury and the Earth itself became a tidally-locked world, one side cast in perpetual sunlight with boiling oceans where some of mankind's remnants have built their floating cities. The Human race is divided in two inimical ethnic groups: the "Whites" and the "Blues"; which have joined forces against the Martian invaders. However, despite fighting their ships, no Human has ever laid eyes upon a Martian.

Biology
Martians are enormous life forms which can hold Human bodies with the tips of their luminous tentacles. They have an "immense hooded brain", and wet skin, and communicate by touching each other's foreheads with their tentacles and transmitting information.

Culture and society
They consider love an "obscure" and "curious" emotion, which they apparently admire. They use gigantic sea nets to scoop Human vessels from the seas like fish; possibly for scientific purposes and/or consumption.
