The anhinga’s neck, bill, and feet all help it catch prey.
The anhinga’s neck, bill, and feet all help it catch prey. The neck can be bent back in an S-shape, and the powerful neck muscles, when tightened, enable the bird to thrust its head forward with great force, like a harpoon. The bill is straight, sharp, and pointed, in the form of a dagger.
