He floated through the warm tidal seas, going with the flow, just enjoying life. His external cilia waved wafting micronutrients to him. Life was easy; life was good. In the warm current, he sensed millions more of his species. Then his awareness lifted as the current brought another bacterium similar to himself within range. His cilia waved more enthusiastically until she noticed. Using her own tail-like flagellum she steered herself closer.
"Hi, how're you," his chemical signals emoted.
"Fine, thanks," she signaled, shaking her body. "You?"
Non-committal. He'd have to up his act if he wanted to reproduce.
"Fancy drifting over to those rocks with me? I hear they've got some really tasty micronutrients over there?" he gestured.
She signaled assent and they made their way over and fed on organic molecules. He found some extra nutrients and his cilia passed some over. He was pleased when she accepted and she absorbed the nutrients into her cell-wall.
He sensed that she was adorable having a perfectly flawless oval-shaped cell in pale gray with a delicate cyan hue that would excite any bacterium, a lovely, long whip-like flagellum extending from her rear for mobility and the sexiest pili tubes he'd ever seen. It made you want to lose your DNA load and reproduce immediately.
