Mithrans

See "Home."

The earliest human description - a long-armed, bird-headed kangaroo;
nude;
small;
brown-furred;
slender beaked;
on each hand, three fingers at right angles to each other;
like Merseians, they sit on their tails;
descriptive names like "Strongtail" and "Rich-in-Peace";
indolent;
but with hidden depths.

I cannot keep such a description in my head while reading the story. All that remains is "something like a kangaroo," which I cannot visualize well anyway. Such aliens would have been impossible on screen until recently but now can be CGIed.
