Mexico’s Sardine Run

Although striped marlins (Kajikia audax) are slower than some of their billfish cousins, their 50-mph speed is plenty fast for me. I try to swim alongside this stealth bomber of the sea as it works a baitball to separate individual sardines from the silvery mass. While getting outpaced by sailfish and black marlin might be […]
