Navy to Use Dolphins and Sea Lions in Anti-Terrorism Fight
P.E.T.A. [People for the Ethical Treatment of Animals], however, claims that this practice is not only an ineffective means of defense, but also a dangerous and cruel use of animals.
If these dolphins and sea lions are used they will be following a long tradition of animals used for military purposes. During World War II, military dogs were used on patrol, as scouts, and even as messengers. And as recently as 2003 the Navy has used Dolphin to detect underwater mines.
