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.

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.
There are essentially two choices of weapon for spearfishing: pole spears and spearguns. The speargun is probably the first thing that comes to mind for most readers - conjuring up images of Seahunt, James Bond, and countless other TV shows and movies. Everyone knows what a speargun looks like - a roughly pistol-shaped device that fires a two-foot steel dart. Everyone probably also has a pretty good idea what a pole spear looks like, but an underwater pole spear is a different in form and use from a terrestrial javelin. Rather than throwing it ( which would be difficult to impossible underwater ) a pole spear ( or "Hawaiian sling" ) has a loop of rubber tubing at the butt end that is used to launch it directly from the hand, the shaft sliding through the loosened hand without ever leaving it.
