… is endemic to the Balearic Islands off the coast of Spain. This species was once present across the archipelago, including the large islands of Mallorca and Menorca. Today it is only found on small, rocky islands with no human inhabitants. Morphologically distinct subspecies have emerged on many of these isolated islands.

- Found in lowland rainforest in the Thai-Malay Archipelago to Borneo. family Agamidae. Females are green speckled, and the males are brown with pronounced crests. Length: up to 13 cm (snout/vent);40 cm (total).
Gonatodes is a genus of dwarf geckos that include many different species. Almost every species has a dramatic and unique color variation (in the males mostly). They mostly live in the forests of South America although some have adapted to live in cities and have been taken as pets.
They eat almost any bug that they can swallow. Some species of Gonatodes are becoming critically endangered due to deforestation.
Most of the species have pointed noses and are rather narrow in body size. However Gonatodes Daudini, shown here is the only one with large scales, bright orange irises and the 3 eye shaped patterns displayed by the males.
Officially described in 2009, both males and females of the chameleon, Furcifer timoni, are very striking, appearing to sport vibrant ‘glam rock’ makeup. According to scientists, the discovery of this distinctive new species was very surprising since the area they call home has been repeatedly and intensively surveyed for reptiles over many years. In total, 11 new chameleon species have been described in Madagascar since 1999.

This roundtail horned lizard (Phrynosoma modestum) is one of the smallest of the horned lizards, reaching an adult length of only about 7.5-10 cm (3-4 in).
This lizard lays egg clutches of up to 9 eggs in early summer. The color of roundtail horned lizards usually reflects the color of the soil in their native habitat. Watch out for them when hiking – they will flatten their bodies and remain motionless when threatened. Their favorite place to hang out is near ant colonies for food.
Introductory chapters cover the biodiversity of lizards and crocodilians both regionally and globally and discuss lizard and crocodilian life cycles, morphology, habitats, diets, and behaviors. Illustrated, fact-filled descriptions of each species and its habitat comprise the heart of the book. The accounts include a physical description of the species plus information about distribution and habitat, behavior and activity, food and feeding, reproduction, predators and defense, and conservation status. Variations within each species are noted as are taxonomic questions, many of which have arisen because of recent advances in genetic techniques.
Around 370 million years ago, a distant relative of a modern lungfish began a most extraordinary adventure—emerging from the water and laying claim to the land. Over the next 70 million years, this tentative beachhead had developed into a worldwide colonization by ever-increasing varieties of four-limbed creatures known as tetrapods, the ancestors of all vertebrate life on land.
This new edition of Jennifer A. Clack’s groundbreaking book tells the complex story of their emergence and evolution. Beginning with their closest relatives, the lobe-fin fishes such as lungfishes and coelacanths, Clack defines what a tetrapod is, describes their anatomy, and explains how they are related to other vertebrates. She looks at the Devonian environment in which they evolved, describes the known and newly discovered species, and explores the order and timing of anatomical changes that occurred during the fish-to-tetrapod transition.
Amateur Herpetologist Discovers New Lizard Species in Somalia
Czech amateur herpetologist Tomas Mazur has discovered a new agama species, Xenagama wilmsi, a small lizard with flat “beaver-like” tail, in Somalia, and found out that this is actually the species most reptile fans keep in their vivariums without knowing it, Mazuch said. The species inhabits the Horn of Africa countries, Ethiopia and Somalia. Its tail is flat at the beginning and it narrows towards its end…
