Our analysis of production and cost begins with a period economists call the short. run. Theshort run in this microeconomic context is a planning period over which the. managers of a firm must consider one or more of their factors of production as fixed.
Sharks have two sets of paired fins on the sides of their body, in the same general position as the main wings and horizontal tail wings of a plane. The shark can position these fins at different angles, changing the path of the water moving around them.
Scientific reconstructions of this shark estimate the dorsal fin 5.5 feet tall, the pectoral fins at 10 feet in length and the tail over 12 feet high. If you were unfortunate enough to have a Megalodon shark swim over you, the pectoral fins would measure 30 feet from tip to tip with a torso in excess of 10 feet thick! The jaws were so large that this shark would be able to swallow a Rhinoceros whole.
