Jooke Robbins, the director of Humpback Whale Studies at the Centre for Coastal Studies in Provincetown told The Cape Cod Times that as humpback whales feed, their mouths open and billow out in a parachute-like manner, obstructing their vision.
Speaking to CNN, Adrian and his father revealed that this trip had been their first time seeing a whale, when they spotted a spout of water moments before he ended up in the animal's mouth.
Without warning, the 24-year-old who was paddling the waves in his inflatable yellow kayak at around 3pm local time was suddenly engulfed by the jaws of the humpback whale.
As he paddled towards him while the whale disappeared from view, he continued to urge him: "Stay calm, grab my rope, grab my rope, if we head for the shore everything will be fine" before steering him away from the area.
Adrian Simancas found himself inside the mouth of the 50-foot animal when he and his dad Dell were kayaking in the choppy waters off the coast off Punta Arenas in Southern Chile on February 8.
