1) Has antenna
2) Mother can birth one litter of babies with multiple fathers
3) Gills to breathe in water
4) Can see clearly in the dark
So welcome to the "cave-creepers."
Margarine huddles on the side of the subterranean lake, her antenna twitching incoherently as she expels streams of goo into the water from her mouth. Around her, seven male cave creepers flutter, their antenna brushing hers and each others. They radiate excitement and concern. As this is the first time they have witnessed birth, they worry about her health. Should she be this pale, her skin this dry? As they have all just become fathers, they are jubilant and relieved. Our children, the movements of their antenna all but shout, our children are healthy, and alive!
Silhouetted against the soft glow of the lake, twenty-two newborn cave creepers flit in the water. Their bodies are soft, slick, translucent. To the fathers, these babies look so vulnerable, so exposed. But they stretch their wings and fluff their neck-ruffs of fur in pride anyways, bragging to each other through flicks and swishes of antenna: See how fast that one swims? She will be a hunter, for sure. And the thickness of his hind legs? He will certainly win his year’s race to the surface.
