A grown male moose (called a bull) can weigh as much as a small car - around 700 kilograms. He grows huge flat antlers every year, which can spread nearly 2 metres from tip to tip. The antlers fall off in winter, and a brand new pair grows back in the spring.
Moose love water. They wade into lakes and rivers to munch on water plants, sometimes putting their whole head underwater. They are also surprisingly fast swimmers. A moose can swim several kilometres without stopping, paddling with all four legs like a giant dog.
Baby moose - called calves - are born in late spring. Within a few hours of being born, a calf can already stand up and walk. Within a week, it can run faster than a human. The mother is fiercely protective and stays close to her calf all summer.
Moose are mostly gentle, quiet animals, but they are big enough that drivers in Canada have to be careful. There are even special road signs all across the country with a black moose silhouette, warning cars to slow down at night.
