When bees swarm, it is in response to other bees that emit pheromones as an alarm. Reptiles and mammals use their Jacobson's organ to sense pheromones. Elephants touch the tips of their trunks to this organ to enact their chemosensory perception of things.
During the American Revolution, the Continental Navy successfully preyed on British merchant shipping and won several victories over British warships. After being disbanded for several years, the United States Navy was formally established with the creation of the Department of the Navy in April 1798.
Thus began the long and prestigious heritage of the United States Navy. Between 1922 and 1972, the Navyâs birthday was celebrated on October 27th, the date of Theodore Rooseveltâs birth. Designated by the Navy League of the United States for Rooseveltâs foresight and vision in elevating the U.S. Navy into a premier force, the celebration of the Navyâs birthday has always been one of pride.
