(1) Their compound eyes look like a periscope of a submarine and allow the lobster to see images in a mosaic pattern.(2) Another classic application of the field lens is in a periscope or endoscope.(3) Visitors can try out a submariner's bunk, learn how to control the boat as it dives, look through the periscope , detect underwater sounds on a hydrophone, climb into a mock conning tower and operate an escape chamber.(4) He also made the submarine commander glare through the periscope with his right eye so that it could be seen more easily.(5) To see above and below the water, mudskippers pop their movable eyes out of the water and move them up and down like a submarine periscope .(6) Although cramped and uncomfortable, these boats were fine examples of engineering, with most of the features to be found on normal-sized boats, including a periscope .(7) There was the conning tower with the periscope easily identifiable inside; there were the access hatches.(8) The cork floated on the surface, its quill upright like the periscope of a submarine.(9) The driver's compartment is equipped with three observation periscopes .(10) Closer examination revealed a pair of compound eyes mounted on movable stalks, protruding from a burrow and rotating independently, like the periscopes of a submarine.(11) Human lookouts are used to detect submarine periscopes .(12) When disturbed, they dive headfirst under water, or they sink slowly into the water until only their heads are above water, like submarine periscopes .(13) Primitive periscopes , made from long wooden boxes with mirrors, were arranged so that an observer could look over the rim of the trench without getting hit by a sniper's bullet.(14) One idea that remained on paper only was to train seagulls to land on periscopes at sea thus giving away the position of a submarine!(15) The commander has seven optical periscopes which provide 360Ôö¼Ôûæ observation and a dedicated sight for weapon aiming.(16) Since mines don't emit sounds, produce heat, make transient sounds or poke periscopes through the surface of the water to attack their prey, minemen have to look for shapes.
