an analogy from Dudley Lynch's book called The Strategy of the Dolphin
A carp symbolized codependent behavior, a shark represented aggressive behavior and a dolphin stood for the ability to cope and excel in a changing environment. "Dolphins" like a challenge and are able to thrive in a tough environment. They are expert at reading the currents of organizational attitudes, searching for clues and monitoring developments. They are very adaptable, swim well in constantly changing water, float in any current, dive in any pool. Being both team players and self-reliant, dolphins can coordinate actions or act completely alone. If things aren't working, dolphins will change tactics until something does work.
Dolphin behavior around sharks is legendary. Using their intelligence and strong will, they can be deadly to the sharks. Bite them to death? Oh, no! Dolphins circle and ram, circle and ram. Using their bulbous noses as amphibious bludgeons, they methodically crush a shark's rib cage until the aggressive creature sinks helplessly to the bottom.
