Cetacean teeth are homodont, that is, all alike shape in shape and not differentiated to perform different functions. Only the narwhal is an exception; one of the two 'eeth in the upper jaw of the male is modified into a forward-projecting, spirally grooved tusk that may reach eight feet or more in length. The teeth are relatively short and conical in shape and are used to grasp the fish and squid upon which most toothed whales feed. The sperm whale feeds heavily upon the squid that live in the deeper parts of the ocean; when its intestine is irritated, it produces ambergris (q.v.). Its throat is large enough to swallow a man.

OEVERAL different kinds of grubs dam-»^ age turf by feeding on its roots. All look much alike shape—ugly, soft-bodied whitish or tan-colored creatures with six legs and often darker colored heads. They are sluggish, usually curled in the shape of the letter C and are found two or three inches beneath the soil surface.

Although grass blades may look alike shape to the [experienced observer, they diverge greatly in size and shape—from short and needlelike in Aciachne to gigantic (12 feet, or 3.6 meters, long and 1 foot, or 0.3 meter, wide) in Ne-urolepis. In addition, the kinds of cells and their arrangement in the upper and lower layers (epidermises) of the blade, and internally, show considerable variation.
