Tigers, like other mammals and birds have an endoskeleton. That is to say that their skeleton on the inside of their body as opposed to insects which have an exoskeleton that covers their entire body.
A Tiger typically reaches a height of about one meter at its shoulder. A tiger will reach around two to three meters from head to rear with a tail that extends about a meter. Tigers range in size from the smallest Sumatrans, in which the females weigh from 75-100 kg; males weigh from 100-140 kg, to the largest Bengal tigers, in which the females weigh 100-160, males weigh 180 to 258 kg.
The collarbone or "clavicle" is not directly attached to the skeleton of the cat but is instead attached to the body by muscle.
