US Navy Will Use Dolphins And Sea Lions For Spying Naval Mines

Dolphin is a very lovely sea animal and gets familiar soon with the human beings. You might have watched on Tv that it performs another task too i.e. it is used for spying the naval mines in the sea. As police or military uses trained dogs to identify the place where explosives are laid under the ground, similarly naval forces use dolphins to identify naval mines under the sea. US navy is extreme expertise for the purpose. Sea lion is also used for this purpose due to its high capability of sense of hearing and going in the extreme depth under the water. Dolphin is another special quality of creating voice waves that when return after hitting some hindrance make the dolphin know the distance of that point. Due to this capability dolphin can identify the naval mines and its this quality is more effective than man made device. Whereas, sea lion under the extreme depth of water and in the very dim light can see and can feel or hear very slow vibrations. The water pressure is too high under the depth therefore, divers when go too deep, on coming back to water surface feel pain in their body. While dolphin and sea lion are save from this pressure.
US navy had initiated work on sea animals during 1950. They at the first stage studied the hydrodynamics of dolphin to improve the working of ships, sub-marines and torpedoes They soon realized that dolphin can substitute the divers in open sea too and it is trust worthy and can be trained for the identification and search of under sea things.
Other sea animals were also used to search for things in the wrecked ships. Special arrangements were made to save them from sharks. In early 1990 when the information of conducting experiments on sea animals came in light many quarters expressed reservations for the program. The organizations working for the protection of the rights of animals claimed that navy is using dolphins as weapons. Afterward, at the end of 1990, "Marine Mammal Commission" termed this criticism baseless.
Today, Us navy is using bottlenose dolphins and California sea lions to identify under sea naval mines. In addition, these animals help in saving the sea ports and naval installations from dangers through sea. They can be prepared for any mission at a notice of 72 hours. The good thing about these animals is that they like their work. US navy claims that they leave them in sea daily and they come back regularly to their assignments. Some times it happened that some of the trained animals did not return back. US navy has initiated the dolphin's breeding program too. After beginning the breeding program, no dolphin was caught from the sea.
