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.
History [edit]. Navy Federal was originally incorporated on January 17, 1933 as the Navy Department Employees' Credit Union of the District of Columbia (NDCU). Only Navy employees who were members of the Federal Employees' Union were eligible to join. The next year, President Roosevelt signed into law the Federal Credit Union Act, which would eventually become the basis of business for the credit union.
