Unfortunately, aquatic animals are also threatened in the Amazon. One of the most iconic animals, and most threatened is the giant river otter. This freshwater otter can grow up to 6 feet in length and weigh up to 75 pounds. With their webbed feet and sharp teeth for hunting fish, these mammals might resemble a sea monster from ocean legends. But, don't be put off by their appearance. Giant river otters are quite sociable, living in families with monogamous parents. Families can frequently be seen frolicking in the river, working together to round up a catch of fish for the day. However, scientists estimate that there are only a few thousand otters left in the wild due to extensive hunting.
