Delaware has a string of artificial reef sites in the Delaware bay, but they are of little interest to divers. Most of the sites are quite shallow and perilously close to the shipping lanes, several of them were actually reduced for this reason. The conditions in the bay are hardly good for diving. The reefs consist mostly of concrete rubble from construction in Philadelphia and other cities on the river. Also shown is New Jersey's sole artificial reef in the bay.
Green algae take many forms, some of which superficially resemble grass and other plants. Cladophora grows in tufts 3"-12" in size. Sea Lettuce - Ulva lactuca - is a green algae that grows in large sheets up to 36" like tissue paper. Small specimens are attached, but large ones are usually found drifting. It is edible and extremely common in protected waters. Enteromorpha algae superficially resembles eelgrass, and like eelgrass may also grow in thick beds.
