Sharks are fish, and virtually all fish breathe through the use of gills. These are the collection of slit-like openings on the sides of fish, located behind the head. Behind the gills are networks of complex capillaries. These networks of tiny blood vessels withdraw oxygen from the water as it passes over them.
Swimming and BreathingMost species of shark breathe by swimming, using the forward motion to pass water over their gills. These sharks must be in constant forward motion, or they will suffocate. This is why dead sharks are frequently found in fishing drift or anti-shark nets. Once entangled in the net, the shark is unable to breathe and cannot free itself in the limited amount of time it has before "drowning.
