"He was a very big Mako shark"
The mako shark "has a remarkable swim speed reaching sustained speeds of 35 kph (with bursts over 80 kph) and has been known to travel over 2,092 km in little over a month."

This video includes some great closeups of the mako's teeth, which Hemingway describes in the novella.
