No, otters do not have opposable thumbs. While they may use their paws and claws to grip objects and move them around, they are not able to grasp and manipulate items in the same way as a human with an opposable thumb.
Generally, the only opposable thumb seen in the animal kingdom belongs to primates, like humans, who have an opposable thumb on each hand. Other animals, like cats and dogs, possess a rudimentary opposable thumb called a dewclaw, which is not as specialized for manipulation as a human’s thumb.

Do otters have paws or hands?
Otters have large paws with webbed toes and five long, slender claws. They are very dexterous, allowing them to manipulate objects and even open shellfish while underwater. Although they do not have hands like primates, the palms and soles of the otter’s paws are adapted for swimming, with numerous sweat glands that help keep the skin from slipping underwater.
The bumps and ridges on the paws provide traction on top of the water, giving them more stability as they move around. The claws are sharp for gripping and tearing food and for use in grooming. Fur also grows in between their toes, providing additional warmth and decreasing drag.
In addition, the hind feet of otters are longer than the front ones, allowing them to take long strides while swimming quickly.
Why are opposable thumbs so important?
Opposable thumbs are incredibly important for a variety of different reasons. For one, having opposable thumbs makes it easier for humans to grip and handle objects, without having to use other body parts — like feet.
This helps us manipulate and control things quickly and accurately. We rely on our opposable thumbs to operate smartphones and computers, open packaging, peel fruits and vegetables, drive cars, eat, and so much more.
In addition, our opposable thumbs aiding in the development of tools and our use of them is what separates us from many other species. This can be seen through our ability to hold and use tools crafted with a great range of complexity — from a simple stone hammer to intricate circuitry — that have helped us in cultivating our land and building our civilization.
Opposable thumbs have been absolutely essential in our success as a species and are the driving force that has allowed us to become the dominant creatures on the planet today.
Are elephants right or left handed?
No scientific studies have been conducted to show whether elephants are right or left handed, so it’s difficult to make a definitive statement about their handedness. Elephant research, which includes studies on their behavior, has suggested that they may be ambidextrous, meaning they can use both their right and left hands in a similar way.
For example, when eating, an elephant may switch between the ends of its trunk to grab food. The two sides of the trunk can be used for different tasks, so an elephant may be able to switch sides depending on the task at hand.
Similarly, elephants may be able to use their right foot as well as their left one when walking.
In addition to the evidence that elephants may be somewhat ambidextrous, studies have also concluded that elephants display different behaviors when using the same body parts. For example, when foraging for food, an elephant may use its trunk in different ways depending on the task.
Such behaviors suggest that elephants may have a preference for either the right or the left hand depending on the circumstance.
Overall, more scientific research is needed to confirm whether elephants are right or left handed, and whether they have a preference for either hand.
Are hamsters thumbs opposable?
No, hamsters do not have opposable thumbs. Like most species of rodents, hamsters have four digits on their front paws, which do not allow them to easily grasp objects like a human thumb does. The lack of opposable thumbs does limit their abilities to manipulate objects, but they compensate by having excellent grip and strong front limbs.
Hamsters also use their incisor teeth to help compensate for their lack of opposable thumbs, as they can chew and manipulate items with more precision than their paws are able to. By combining their teeth, paws and powerful claws, hamsters are able to maneuver items in order to create comfortable nests, locate food and explore their environments.
