    Seabeach amaranth (Amaranthus pumilus) is an annual plant found on the dunes of Atlantic Ocean beaches. It was first collected in the early 19th Century in New Jersey, and its range was subsequently determined to extend from Massachusetts to South Carolina. Although originally described as abundant, the plant has declined precipitously throughout the 20th Century as a result of habitat destruction and alteration, incompatible beach grooming practices, and recreational activities. In Delaware, the plant is known only to Sussex County.

    Red knots (Calidris canutus ssp. rufa) are teacup-sized migratory shorebirds that are true masters of long-distance aviation. These birds fly more than 9,300 miles from South America to the Arctic each spring and repeat the trip in reverse each autumn. Before returning to their summer habitat in the Arctic, they stop off in Delaware to feed on the eggs of horseshoe crabs to fuel up for the long flight.
