State Bird: Blue Hen
Adopted on April 14, 1939, the Blue Hen chicken had long been used as a motif in numerous political campaigns and in many publications. During the Revolutionary War, the men of Captain Jonathan Caldwell's company, recruited in Kent County, took with them game chickens that were said to be of the brood of a famous Blue Hen and were noted for their fighting ability. When not fighting the enemy, the officers and men amused themselves by pitting their Blue Hen chickens in cockfights. The fame of these cockfights spread throughout the army and when in battle, the Delaware men fought so valiantly that they were compared to these fighting cocks.

State Fish: Weakfish
In recognition of sport fishing’s overall recreational and economic contributions to the state of Delaware and of the specific values of the weakfish (Cynoscion genus) as a game and food fish, the state Legislature adopted the weakfish as Delaware's State fish in 1981. This fish is also known as sea trout, gray trout, yellow mouth, yellow fin trout, squeteague, and tiderunner.

State Marine Animal: Horseshoe Crab
Recognizing its great importance and value, the horseshoe crab was designated as Delaware’s official marine animal on June 25, 2002. These invertebrates contain a compound, limulus amebocyte lysate (LAL), that is used to detect bacterial poisons in certain medications, vaccines and medical devices. Chitin, a natural polymer found in the horseshoe crab’s shell, is used to make bandages. The horseshoe crab is used in vision studies, because their complex eye structure is similar to the human eye. It is the principal food source for over a million shore birds. Delaware Bay is the home to more horseshoe crabs than any other place in the world.

State Wildlife Animal: Grey Fox
Adopted June 10, 2010, the grey fox is a unique and primitive species, believed to be between 7 and 10 million years old, which is indigenous to Delaware. It is a swift and powerful animal capable of running up to 28 miles per hours and the only member of the canid family which is able to climb trees. The fourth grade students at Joseph M. McVey Elementary School, as part of teacher Paul Sedacca's lessons on persuasive writing, suggested that the grey fox be designated as Delaware's official state wildlife animal. Since it does not hibernate, the students said that it is "always ready like our soldiers at Dover Air Force Base".
