The black drum, also known as the drum or drummer, is a species of marine ray-finned fish belonging to the family Sciaenidae, the drums and croakers. It is found in the western North Atlantic Ocean off the eastern coast of North America. Though most specimens are generally found in the 5-30 lb (2–14 kg) range, the largest black drum was just over 113 lb (51 kg). They are often black and/or gray in color with juvenile fish having distinctive dark stripes over a gray body. Their teeth are rounded and they have powerful jaws capable of crushing oysters and other shellfish. Black drum are capable of producing tones between 100 Hz and 500 Hz when performing mating calls.

Oyster is the common name for a number of different families of salt-water bivalve molluscs that live in marine or brackish habitats. In some species, the valves are highly calcified, and many are somewhat irregular in shape. Many, but not all oysters, are in the superfamily Ostreoidea.
