A close-up vertical video captures a leopard gecko standing on a white mat with black grid lines. The gecko, with its distinctive yellow, black, and white spotted pattern, looks directly at the camera with wide-open eyes. Behind the gecko, a black computer keyboard is visible, and above it, a small red light glows. On the mat, near the gecko's front paws, there are traces of a white powdery substance and a reddish stain. The gecko remains still for a few seconds before swiftly extending its pink tongue out of its mouth and then retracting it, briefly revealing the inside of its mouth before it closes again.
