Sea Serpent

In August 1848, during a voyage to Saint Helena in the South Atlantic, the officers and crew of HMS Daedalus observed a creature 60 feet long that held a peculiar maned head above the water.

What was it? The English biologist Sir Richard Owen supposed it was an elephant seal; others have suggested a “super eel,” a giant squid, and an upside-down canoe. We’ll never know.
