Some reptiles have a parietal eye (or third eye), like the small grey dot on the top of this carolina anoles head. The parietal eye may be photo-receptive and helps with thermoregulation and the regulation of the circadian rhythm.
A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre area in South America.
Scientists have recently discovered a rare, solitary type of bee that makes tiny little nests by plastering together flower petals. Each nest is a multicolored, textured little cocoon - a paper-mache husk surrounding a single egg, and protecting it while it metamorphoses into an adult.
With an adult body length of only 14 to 16 centimeters, and weighing as little as 4 ounces, the endangered pygmy marmoset is one of the smallest primates discovered. They are normally found in the rain forest canopies of South America.
A type of gastric brooding frog, the likely extinct Rheobatrachus vitellinus hador hasa unique mode of reproduction: Females swallowed their eggs, raised tadpoles in their stomachs, and then gave birth to froglets through their mouths (pictured above).
Last seen in 1985, the Australian frog is one of the ten species that conservationists most hope to find during a first ever global search for lost amphibian species.
I did a little of this when I was a Student Assistant in the Department of Entomology and Plant Pathology at UT. Came across some pretty weird things that wound up in our traps.
The porcupines found in North and South America are good climbers and spend much of their time in trees. Some even have prehensile (gripping) tails to aid in climbing.
This image of Centaurus A shows a spectacular new view of a supermassive black holes power. The X-ray jet in the upper left extends for about 13,000 light years away from the black hole.
