The Sea Forest is an unusual and probably unique feature of the Nonestic Ocean.
The Sea Forest consists of trees rooted to the sea floor and growing up to break the surface of the Nonestic Ocean. The trees have green and silver leaves, and support vines made of coral, with growths of mushrooms at their water-lines.
The Forest nourishes a wide range of life forms, including fish, clams, and crabs. The area also features some special and hybrid forms of mixed sea and land life — monkey fish, flying fish with crab claws, and sea lions with scaly manes, tufted tails, and sharp claws on their forelegs.
