How is the tongue of a hummingbird shape?

The tongue of a hummingbird is a highly specialized organ that is perfectly adapted for the bird's unique feeding habits. It is long, thin, and shaped like a straw. The tongue is also covered in tiny barbs that help the hummingbird to extract nectar from flowers.

The hummingbird's tongue is also very flexible. It can be extended and retracted rapidly, and it can also be moved in different directions. This allows the hummingbird to reach the nectar in flowers of all shapes and sizes.

The hummingbird's tongue is a marvel of nature. It is a perfect example of how evolution can produce organisms that are perfectly adapted to their environment.
