Jet-Propelled - But It Didn't Get Away -- Scientific assistant Edgar French, of Twickenham, has his own private exhibit aboard the Royal Research Ship 'Discovery II' now berthed at London Dock for inspection by delegates to the Commonwealth Oceanographic Conference being held at Wormley, Surrey.The creature is a squid which he caught with a red and line off the Azores in September. It is believed to be the fastest animal in the sea as it 'jet-propels' itself by sucking in water and squirting it out through a hole in its head. October 16, 1954. (Photo by Reuterphoto).
