Diagram showing the appearances and relative sizes of 18 basal species of Ceratopsians (frilled, beaked dinosaurs typified by Triceratops). Animals are shown in order of geologic stage from left to right and top to bottom, with species names and stage information as annotation.
Ceratopsians were beaked herbivores who lived in what are now North America and Asia, during the Cretaceous Period. Early members such as Psittacosaurus were small and bipedal. Later members, including ceratopsids like Centrosaurus and Triceratops, became very large quadrupeds and developed elaborate facial horns and a neck frill.

A late nineteenth century photo of snake charmers in Tangier, Morocco. Snake charming is the practice of apparently hypnotising a snake, and the performance may use musical instruments and other street performance techniques. The practice as it exists today probably arose in India, where it remains widely practiced, and spread throughout Southeast Asia, the Middle East, and North Africa.
A rare albino American Alligator (Alligator mississippiensis), a resident of the California Academy of Sciences in San Francisco, California. Typically olive, brown, gray or nearly black in color, the species is native only to wetlands of the Southern United States.

Two Trachylepis maculilabris skinks mating. Skinks are lizards that generally have no pronounced neck and relatively small legs. Females may be egg-laying or give live birth, with many of the latter being ovoviviparous (hatching eggs internally and giving birth to live offspring).
The Northern Curly-tailed Lizard (Leiocephalus carinatus) is a lizard species from the family of curly-tailed lizards (Leiocephalidae). It is native to the Bahamas, the Cayman Islands and Cuba, but was released intentionally in Palm Beach, Florida, in the 1940s. An active, robust lizard, it is mostly terrestrial and will retreat into a burrow or cavity when frightened. It prefers sunny areas with loose rubble and rock.
The African striped skink (Trachylepis striata) is a skink native to southern Africa. Individuals are brown or bronze-coloured with two yellowish stripes that run lengthwise on either side of the spine. Both sexes grow to a length of about 25 centimetres (10 in).

A White-headed dwarf gecko (Lygodactylus picturatus) whose tail is missing due to autotomy, the act of an animal severing its own appendages, usually as a self-defense mechanism designed to elude a predator's grasp. The detached tail will continue to wriggle, distracting the predator's attention. The lost body part may be regenerated later.
The Gold dust day gecko (Phelsuma laticauda) is a diurnal species of day gecko native to Madagascar and the Comoros, although it has been introduced to Hawaii and other Pacific islands. It grows to about 15–22 cm (6–9 in) in length and is bright green or yellowish green with rufous bars on the snout and head, and red bars on the lower back.

The Sinai Agama (Pseudotrapelus sinaitus) is an agamid lizard native to northern and eastern Africa and the Middle East. It grows to about 25 cm (10 in) long, with the tail accounting for up to two thirds of the total length. It is active during daytime and feeds on insects and other arthropods and plants. During the breeding season, males become a striking blue colour to attract females.
The American five-lined skink (Eumeces fasciatus) is one of the most common lizards in the eastern United States, as well as one of the five lizard species extant in Canada. It is a small to medium sized skink growing to about 12.5 to 21.5 cm (4.9 to 8.5 in). Juveniles (as seen here) are dark brown to black with five distinctive white to yellowish stripes running along the body and a bright blue tail.
The common collared lizard (Crotaphytus collaris) is a North American lizard well known for its ability to run on its hind legs. Its length, including the tail, can reach up to 12 inches (30 cm). Its name reflects its distinct coloration, which includes bands of black around the neck and shoulders that resemble a collar.
The Italian wall lizard (Podarcis sicula) is native to southern and southeastern Europe. As the name suggests, it is the most abundant lizard species in southern Italy. The species is known for having been subject to "rapid evolution": In 1971, ten adult specimens were brought to the Croatian island of Pod Mrčaru from a neighbouring island, where they founded a new bottlenecked population. After the Yugoslav Wars, scientists found that the Pod Mrčaru population differed greatly from the original group, although the two are genetically identical. The most surprising difference was that individuals on Pod Mrčaru had developed cecal valves, "a brand new feature not present in the ancestral population".

Ophiuchus is a constellation commonly represented in the form of a man grasping a large snake, and was formerly referred to as Serpentarius. It is a large constellation straddling the celestial equator and near the centre of the Milky Way as viewed from Earth, being surrounded by Aquila, Serpens, Scorpius, Sagittarius and Hercules. To the north of the serpent's tail is the now-obsolete constellation Taurus Poniatovii, while to its south Scutum. Ophiuchus's brightest star, Alpha Ophiuchi, represented here by the right eye of the snake charmer, was traditionally known as Rasalhague, from the Arabic meaning 'head of the serpent charmer'.
This illustration is plate 12 of Urania's Mirror, a set of 32 astronomical star chart cards illustrated by Sidney Hall and first published in 1824, featuring artistic depictions of Ophiuchus, as well as Taurus Poniatovii, Scutum (here referred to as "Scutum Sobiesky") and Serpens.

Bosc's fringe-toed lizard (Acanthodactylus boskianus) is a medium-sized species of lizard found in northern Africa and the Arabian Peninsula. Active during the day, they are energetic foragers for insects and other small invertebrates, and are one of the most common lizards in their range. Males and females are similar in appearance, both having a snout-to-vent length of between 5 and 8 cm (2.0 and 3.1 in), but males are usually larger. The feet have long slender digits that are fringed. The dorsal surface is olive-grey with five longitudinal dark stripes, the middle one of which subdivides at the neck, while the ventral surface is whitish, but in the female, the underside of the tail becomes suffused with red during the breeding season. In juveniles, the tail is blue.

Ptyas mucosa, the Indian rat snake, is a common species of colubrid snake found in parts of southern and southeastern Asia. Growing to a length of 1.5 to 1.9 m (5 to 6 ft), they are very slender, diurnal and semi-arboreal. They inhabit forest floors, wetlands, rice paddies, and farmland, and are frequently found in urban areas where rodents thrive. They are harmless to humans, but are fast-moving and adept at catching the small mammals, birds, amphibians and other reptiles on which they feed, subduing their prey by lying on and suffocating them.

Calumma crypticum, the blue-legged chameleon, is a species of chameleon found in eastern Madagascar. As with other chameleons, an individual's colour is variable and depends on its surroundings, the ambient temperature, and variations in the level of light. The species is usually quite colourful, with rich browns, blues and greens; the legs are often marked with blue. This C. crypticum individual was photographed in Ranomafana National Park, Madagascar, and can be identified as a male by its long snout with a horn-like protrusion.
