Drums

Drums are so named for their ability to make drumming sounds with their swim bladder. Actually, many fishes are capable of making sounds, from squeaks to growls, although not all Drums can "drum". Kingfish lack a swim bladder but still vocalize by grinding their pharyngeal (throat) teeth.

The Northern kingfish, Menticirrhus saxatilis, is popular with many saltwater anglers, and it's no wonder. These fish are known to put up a good fight, and their tasty, white meat is well worth the effort.


Weakfish

Cynoscion regalis

The Weakfish is a member of the croaker family. The family name is derived from the ability of the males to make a drumming or croaking noise.

The croaker is a member of the Sciaenidae, or drum family, which includes the black drum and weakfish. Their name comes from the sound they can make by vibrating their swim bladders.

Gammarus

Amphipod crustaceans typically range in size from 2 to 50 mm, although a few may be larger. Amphipods are common in aquatic ecosystems throughout many parts of the world, inhabiting marine, brackish, and freshwater environments. A few species are also terrestrial. Amphipod means "different foot", a reference to the varied legs that are evident in the illustrations, as opposed to isopods.

The order Amphipoda, which contains nearly 7,000 described species, is divided into three suborders: Gammaridea, Caprellidea, and Hyperiidea. Gammaridea, with more than 5500 described species, is not only the largest amphipod suborder but also contains all of the freshwater and subterranean taxa. Approximately 21 superfamily groups, 95 families and more than 1000 genera are recognized within this suborder.
