Anole lizards are highly territorial and typically stick close to their home tree. So, what happens when a team of researchers carries them far away into the forest? Will they find their way back? Dr. Manuel Leal and colleagues designed an experiment to find out. They displaced the lizards from their home territories and then tracked their movements using radio transmitters. Most of the lizards were able to orient themselves and head in the right direction, with some making a beeline back to their original tree in less than 24 hours.

Working in the islands of the Caribbean, biologist Jonathan Losos has discovered the traits that enable dozens of anole species to adapt to different vertical niches in the forest. Differences in limb length, body shape, and toepad size allow different species to flourish on the ground. However, lizards living on thin branches or high in the canopy have different characteristics. These varied adaptations have played a key role in reproductive isolation and the formation of new species.
Identifies physical characteristics, adaptations, and survival tactics of various kinds of reptiles. Segment 1, Snakes: Describes how snakes move, eat, and reproduce. Segment 2, Crocodilians: Compares and contrasts alligators and crocodiles. Segment 3, Lizards: Looks at some unique physical adaptations of various lizards, such as basilisk lizard, Komodo dragon, Gila monster, and chameleon. Includes suggested classroom activities after each segment.
Towering gypsum dunes span hundreds of square miles in New Mexico's White Sands National Monument, and hundreds of animal species thrive in this unique ecosystem. The lizards living in White Sands National Monument have attracted biologists from the University of California, Berkeley. The lizards are undergoing adaptation and speciation on an extraordinarily rapid timescale. Part of the “Science Nation” series.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The class transforms into lizards in an effort to save Liz, who the class thinks is in trouble after leaving school. They find him at the mysterious "Herp Haven." Will the class be able to save Liz, or is she even in any danger in the first place?
Students learn the unique features of reptiles by viewing footage of snakes, lizards, and turtles in their natural habitats. Concepts and terminology include cold-blooded, scales, shell, and eggs.
Explore the narrator’s backyard to get an up-close look at some scaled friends. Students will learn about the characteristics of reptiles. Animals discussed include turtles, snakes, and lizards. Part of the "Everyday Science for Preschoolers" series.
Unlike lizards, humans cannot regrow limbs. But humans can regenerate their livers. A MIT student explains how and why. Part of the "Science Out Loud" series.
