Brinker-roo

Brinker-roos are a non-sapient species native to Europa presented as an imaginary example of extraterrestrial life in the book Picture Atlas of Our Universe, by National Geographic.

Biology
Brinker-roos exhibit bilateral symmetry and use the only pair of limbs they have to skate across the ice plains of the homeworld, Europa. Their round head is supported by a long neck, roughly as long as the tail. They have a pair of large blue eyes with vertical pupils. Six appendages grow out from the back of their head.

As they are autotrophs and live exposed to the vacuum, brinker-roos have neither mouth nor nostrils. The skin shows green pigmentation as brinker-roos are photosynthetic, except for the turquoise spots under the belly. Most noticeably, a coil-like crest begins at the head and ends midway in the tail, which brinker-roos use to extract energy from Jupiter's strong magnetic field.
