USS Squalus
USS ''Sailfish'' (SS-192), was a US , originally named ''Squalus''. As the ''Squalus'', the submarine sank off the coast of New Hampshire during test dives on 23 May 1939. The sinking drowned 26 crew members, but an ensuing rescue operation, using the McCann Rescue Chamber for the first time, saved the lives of the remaining 33 aboard. The submarine was salvaged in late 1939 and decommissioned. The submarine was recommissioned as the ''Sailfish'' in May 1940, and conducted numerous patrols in the Pacific War during World War II, earning nine battle stars. She was decommissioned in October 1945 and later scrapped; the conning tower remains on display at Portsmouth Naval Shipyard in Kittery, Maine. Construction of ''Squalus'' Her keel was laid on 18 October 1937 by the Portsmouth Naval Shipyard in Kittery, Maine, as ''Squalus'', the only ship of the United States Navy named for the squalus, a type of shark. She was launched on 14 September 1938 sponsored by Mrs. Thomas C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Squalus
''Squalus'' is a genus of dogfish sharks in the family Squalidae. Commonly known as spurdogs, these sharks are characterized by smooth dorsal fin spines, teeth in upper and lower jaws similar in size, caudal peduncle with lateral keels; upper precaudal pit usually present, and caudal fin without subterminal notch. In spurdogs, the hyomandibula (the bone connecting the braincase to the jaws) is oriented at a right angle to the neurocranium, while in other sharks, the hyomandibula runs more parallel to the body. This led some to think that the upper jaw of ''Squalus'' would not be as protractile as the jaws of other sharks. However, a study that compared different jaw suspension types in sharks showed that this is not the case and that ''Squalus'' is quite capable of protruding its upper jaw during feeding.Wilga, C.D., Motta, P.J. & Sanford, C.P.
