The document summarizes information about two types of mako sharks: shortfin and longfin mako sharks. Shortfin mako sharks are the fastest shark species and can swim up to 70 mph. They have attacked some humans but rarely kill people. Longfin mako sharks prefer upper ocean areas and are also very fast, though they are generally shy and do not attack humans. Both sharks are found in oceans around the world and near eastern coasts of North and South America and in the Sea of Japan. However, both shortfin and longfin mako sharks are endangered due to overfishing by humans for sport and for their fins, which are used in shark fin soup.
