Female Concave-eared Frogs Draw Mates With Ultrasonic Calls:

Most female frogs don't call; most lack or have only rudimentary vocal cords. A typical female selects a mate from a chorus of males and then --silently -- signals her beau.

Worms Triple Sperm Transfer When Paternity Is At Risk:

Scientists used to think that hermaphrodites, due to their low position in the evolutionary scale, did not have sufficiently developed sensory systems to assess the "quality" of their mates.

This ability is even more refined as they are able to transfer more sperm to more fertile partners.
