A large bay that protrudes northeast from Lake Huron into Ontario, Canada, is called Georgian Bay. A notable feature of the lake is Manitoulin Island, which separates the North Channel and Georgian Bay from Lake Huron's main body of water. It is the world's largest lake island. Major centres on Georgian Bay include Owen Sound, Wasaga Beach, Collingwood, Midland, Penetanguishene, Port Severn and Parry Sound.
Starfish appear radially symmetric, but they are actually classified as bilaterally symmetric organisms. That is actuall wrong...they are radially symmetrical, but they do devâ¦elop from bilaterally symmetrical larvea From PattiVan: Think of the starfish like bicycle wheel and the legs are its spokes. The spokes are placed in a radial fashion from the center leading out; so the starfish has radial symmetry.
Like the hydra, the jellyfish has a nervous system characterized by a series of interconnected nerve cells (a nerve net). The nerve net surrounds the whole body of the jellyfish. Shown to the left is a statocyst. When the animal moves and body is tilted, the statocyst makes contact with the cilium.he nervous system of the starfish is very simple...there is no brain and there are not even any ganglia to coordinate movement. The nervous system is characterized by a nerve ring that surrounds the mouth. A radial nerve branches off of the nerve ring and extends to each arm.
