The dolphin has special membranes analogous to man's vocal cords. It can make a variety of noises such as chirps, pops, clicks, squeaks, groans, whines, and other sounds in frequencies from 3000 to 30,000 cycles per second. researchers say the dolphin can mimic human- created sounds such as laughter, whistles, and even word syllables in high frequency ranges. An electronic device, the sceptron, has been contrived to "memorize" sounds of the dolphins, to catalog dolphin-sounds, and record communication patterns. It is even speculated that the fish could ultimately inform man about such matters as missile cones falling into the sea, current temperatures, land formations, and so on.
