Swift indicated that there is a fish called the stargazer that would also make an interesting robotic survellience system. Which could be used in place of a fully robotic AUV Autonomous Underwater Vehicle. The fish It lies in the bottom of water sources and looks a lot like a death mask. It explodes vertically out of its lair and grabs fish, but might also rest on the bottom of a river and guard it and then come up for pictures if someone tried to cross or in wartime take out the infiltrating enemy, as it would be safer than landmines, which lay there for years after a war until some poor civilian trips the device and blows off a limb.
The device would have a positioning GPS and could be detonated after the war or picked up. The robot could do the same thing as the evolved organic fish, but come out of the water and react like a heat seeking missile taking out warm-blooded people as it moved parallel to the surface of the river. I suppose like a flying MAV Micro-Air Telephone Number List Vehicle "Pigeon" single mission bomb maybe used someday. Or maybe to fly in undetected as a fake robotic bird and take pictures. One problem with using robotic camels is they sound expensive to make and what about roadside bombs taking out your camel? Ah ha, A Trojan Camel indeed, maybe I read too much history, but it could work.
The fish idea is totally interesting and could also be inflatable and blow up into a balloon and then go into the air for surveillance. I had designed a robotic manta ray like that or at least did some drawings and figured out the costs.Swift said that there's also an eel called the snake ell that is found in the area of Indonesia. It burrows into the volcanic sands so that only it's head is sticking out of the water. Perhaps you might have seen it on the Science, Discovery or Animal Channel? This could be used to spy on China and Southeast Asia, because they have over 2000 industrial spies in our country already looking for military contractor secrets.
