Geckos are small to middle size lizards. Lizards are reptiles. There are 1196 different kinds of geckos. They live in many warm countries. Some kinds of geckos go into people's houses. People are often happy to have them, because geckos eat many insects.
Unlike most lizards, geckos have voices. A gecko sounds a little like a bird or a frog. In some languages these lizards have names that sound like their calls, for example, both English and Indonesian call one kind gecko (gek KO) and tokay (to-KAY). Another kind of gecko, with a different sound, is called chicak (CHEE chak).
Many kinds of geckos can walk on walls, windows and ceilings. They can do this because they have special toe pads. A microscope can show that each toe pad is made of thousands of hair-like structures. Each of these structures branches into many smaller ends.
