alien life form n.

It’s a unicellular creature—Janna told me—an alien life-form, developed along lines unfamiliar to us.

As in the past, I have tried not to invent things that are too far removed from life as we know it on this Earth. The weird ‘whip’, for instance, has its Earthly counterpart not only in the ant-eater, but in the sphinx-moth, which sports a hoselike tongue a good deal longer than its own body. Cousins to the ‘Venusian buzzard’ can be found under any microscope in the biology lab. While the Murri, of course, finds its obvious image in the Proboscis Monkey…. I do this because I feel that if a reader has some basis of comparison, when reading about alien life forms, he will be able to visualize the story more clearly and perhaps give himself an added measure of enjoyment and appreciation.

For just as on Earth sentient life can exist in the freezing Arctic wastes, the torrid jungles, the sea’s greatest depths—so we know it is possible for alien, unique life-forms to exist on each of our planetary neighbors, equipped mysteriously to combat every force known to science.
