Moose Submerge To Reach Aquatic Plants

6-24-13 moose eating after submerging 576The highlight of a recent trip to Maine was watching a bull moose feed on submerged aquatic vegetation. It would swim a short distance, and then sink, much like a submarine, until only the top of its back was visible, and then it, too, completely disappeared, leaving no sign of a moose. Seconds later the moose’s head would reappear, with its mouth full of green plants. When these plants were consumed, the moose would submerge underwater again and come up with another mouthful. It proceeded to do this at least a dozen times before eventually swimming to shore. When moose are feeding on submerged vegetation they are capable of reaching plants in water over 18 feet deep, and they can remain under water for up to 50 seconds or longer before resurfacing. It’s thought that they remain submerged by paddling and perhaps by releasing air from their lungs.
