In the remarkable encounter off the coast of Chilean Patagonia, kayaker Adrián Simancas experienced a brief but harrowing moment inside the mouth of the marine giant. The viral incident, which occurred in Chile's Bahía El Águila near the Strait of Magellan, was captured on video by his father, Dell Simancas, who was kayaking nearby.

A Chilean man was given the scare of a lifetime when he briefly ended up in the mouth of a humpback whale while kayaking off Chilean Patagonia, reports say. The father of Adrián Simancas was recording the kayaking excursion Saturday in the Strait of Magellan when the whale suddenly emerged and Simancas and his kayak disappeared.
