What is "porpoises"

Usage examples of "porpoises".

The two porpoises in the water with Steve had functional blowholes and were programmed to emit the same high-pitched, sonarlike cries as do the real animals.

Anyone listening with hydrophones or studying a sonar scope would be confused, would judge that a school of porpoises had penetrated the cavern and then gone berserk.

It was microminiaturization at its best, and with such manner of packaging, the porpoises became a reality.

So the porpoises were born with their constant-energy source, their marvelous articulation and shape and movement.

Not a fixed distance at all, but a computer-directed variation resembling the actions of two porpoises at sea, moving closer and then a greater distance away, slipping beneath the surface and then sliding along the top with the dorsal fin exposed.

But following a straight line would have been a dead giveaway that the porpoises were phonies, and so the computer was programmed to follow an erratic course, much as porpoises might have done.

If the porpoises were sighted by their dorsal fins as these cut the water, they would fail to attract any particular attention.

The slow-moving fins of the two porpoises were too promising a target.

If the men in the patrol boats had seen the porpoises, they might confuse the chattering, high-pitched squeal for real animals.

Certainly not the orcas and the porpoises, probably not the catodons and their relatives.

That explains why there were no catodons, or orcas of porpoises, participating in the attacks on the towns.

This was a very warm part of the sea, and calm, and was alive with porpoises and sharks, with fins cutting the water everywhere.
