Animal shots of the week

Baby river otter Molalla, or "Mo" for short, is weighed at the Oregon Zoo, Friday, March 15, 2013, in Portland, Ore. Molalla weighs about 2.5 pounds and was born Jan. 28, 2013. They try to weight the river otter when they can but they have to be fast and sneaky. When the mother leaves to go take a dip in the water they quickly shut the door and take Mo out to get his weight and then quickly put him back in the nest. (AP Photo/The Oregonian, Benjamin Brink)
