On the outside, Daleks resemble human-sized salt and pepper shakers who are five to six feet (152 to 183 cm) tall. On the top, they have a rotating dome with a telescope for seeing. They have two arms. One arm has an energy weapon (or "death ray"), which looks like an long egg beater or the framework of a paint roller. In some episodes, this could also fire a gas or projectiles. Their other arm is a telescope with a plunger on the end, which they use as a hand. The actual Dalek creature inside the metal casing is very rarely seen. It looks like an octopus or a squid.
