A member of the platinum group of metals which, unsurprisingly, includes platinum, rhodium is most commonly found mixed with other platinum group metals. This makes it difficult to extract, which can only increase its value.
What is a reptile? Reptiles are animals that are cold-blooded. Most reptiles lay eggs and their skin is covered with hard, dry scales. What does cold-blooded mean? Animals that are cold-blooded don't automatically maintain a constant body temperature. They have to lay out in the sun to keep their body heat up.
In cold conditions they become sluggish and don't move around much. There are four main groups of reptiles: turtles and tortoises; lizards and snakes; crocodiles and alligators; and the tuatara. The heaviest reptile is the saltwater crocodile, weighing up to 2,000 pounds. The smallest is the dwarf gecko, measuring only 3/4 of an inch.
