Basic Anatomy Defined
Fins appear both singular and in pairs. In general the fins work together allowing the shark to maintain balance when swimming. They help to control speed, acceleration, breaking/slowing down, turning ability and tracking. They also help to prevent pitch, rolling and yaw.
*Finning is a process by which the fins are removed from the shark in order to
sell to markets for Shark Fin Soup, a known delicacy.
The shark, usually alive after being finned, is then thrown back into the water
and dies from trauma and drowning. It is a cruel practice which is leading to
the decline of certain species of sharks and is banned in some countries,
including the United States.
