The image is a close-up of a marine iguana's head and neck. The iguana is facing towards the right side of the image, with its head slightly tilted upwards. Its body is covered in scales and its eyes are dark and alert. Its mouth is slightly open, revealing its sharp teeth. The background is blurred, but it appears to be a rocky surface with small pebbles scattered around. The image is taken from a low angle, making the iguana the focal point of the frame.
