The leafy Sea Dragon at the Monterey Bay Aquarium looks like a drifting clump of seaweed. It is found along the southern and western coasts of Australia. These seahorse cousins disguise themselves as seaweed with dozens of leaflike fins. The fins are not used for propulsion, but serve only for camouflage. They grow to about 8-10 inches in length.
