Claws mean a curved pointed horny nail on each digit of the foot in birds, lizards, and some mammals. Claws are present at the end of the toes in every bird. The radius of the curvature of the nails depends on the size of the bird means as large as a bird; the curve will be higher. The claws tend to be straight in ground-dwelling birds like ratites, penguins (some species), chickens, etc. Penguins also have webbed feet with visible claws.
How do penguin claws are useful?
Penguins have sharp claws, and they are not retractable means they cannot pull back. They are set far back on the body, which helps the penguins to stand vertically and in an upright position. Penguin maintains less contact of feet and flippers with the ice instead of a point in the air, which leads to release less body heat.
They help to get a grip on ice and support to walk on land, but penguins cannot run or walk as fast as other flightless birds, for example, ostrich, kiwi, etc. They point their feet in the air, minimizing contact with the ice. This way, these penguins release less body heat.
Conclusion
From the above discussion, we can conclude that – Yes, penguins have webbed feet with visible claws.
