Moose feed on a large variety of foods. They browse on the twigs and leaves of many kinds of plants.. Grasses and marsh plants are also sought.
Aquatic vegetation growing in lakes and streams is particularly relished in summer. During this season of the year, animals are seen at the edges of water or feeding in it. Adult moose will stand virtually submerged in deep water, lowering their heads underwater, grazing for long periods of time on underwater growth. Where a moose cannot reach these succulent plants, it can actually dive in deep water (up to 20 feet), remaining below for up to one minute.
