A caisson gate, constructed off heavy gauge steel with several tons of ballast in the keel, is a barrier used to dam off the open end of a dry dock. The gates originated from the U.S. Navy and range in size from 110-140 feet long and roughly 30-40 feet high, with a width of 25 feet. The first deployment of a caisson gate occurred on the Atlantic City Reef in a "patch" reef now called the William Kane Reef in honor of the first New Jersey Artificial Reef Coordinator, William "Bill" Kane Figley.

Once the structure is fully flooded, it will have no more reason to remain upright and will fall over flat.

Hermit Crabs

Hermit Crab

Hermit crabs live inside empty snail shells in shallow water along beaches and in estuaries, small specimens on mudflats and large ones offshore. Some hermit crabs are entirely terrestrial, needing the water only to lay eggs. In the South Pacific, there are types that actually climb trees and very large ones that don't bother with a shell as adults.

The size of the crab determines what kind of shell, and upgrades are required as the crab grows. The Flat-Clawed Hermit Crab Pagurus arcuatus (right) is the largest in our area, and will often use Moon Snails and Whelks, but you will only find the big ones in deeper water. Small ones use Periwinkles and Oyster Drills.
