Brookesia micra is the smallest chameleon in the world, measuring only up to 1.2 inches long when fully grown. They are only found on a tiny rock islet called Nosy, off the northern tip of Madagascar, which was only recently discovered. Here, they live in the cracks of the island’s rocky terrain. They have a limited range of movement, which is said to be explained by their extreme dwarfism.
4. Texas blind salamander – Texas
As the name suggests, Texas blind salamander, Eurycea rathbuni, lacks vision because of an unusual absence of eyes. It also hasn’t got any skin pigment, and it’s got frond- external gills coming out of its neck. Most of the time, you’ll find it roaming in the water-filled caves connected to the Edwards Aquifer in Hays County, Texas, where it lives in absolute darkness. Despite its limited vision, this species makes a very skilled predator of snails and shrimp, which it catches by sensing pressure waves in the water.
