In medicine, ultrasound is used to detect changes in appearance, size or contour of organs, tissues, and vessels or detect abnormal masses, such as tumors. In an ultrasound examination, a transducer both sends the sound waves and receives the echoing waves.

Anemones are fish-eating animals that look like underwater flowers and have hundreds of poisonous tentacles. Clown fish find most of their food by mooching off the anemone. Clown fish wait until the anemone paralyzes and eats a fish, then helps itself to the bits which the anemone doesn't eat.
