Borneo tattoos do not just mark physical journeys. Some represent big life events, such as fathering children etc. For example, there is a tattoo a man can have done on his hand called the Entegulun. You can only have this if you have taken heads. Most tattoos are for protection, for example the tattoos on the throat (pantang rekong) are meant to give strength to the skin on the throat, to stop the bearer's enemies from being able to sever the bearer's head. Males and females of high status would get the throat tattooed. It symbolizes an individual who is highly accomplished in a field of their life; e.g. a warrior who has taken many heads, or a great shaman, or a headman of a longhouse, or a great carver or artist, etc. The tattoos on the back (Ketam Itit/Ketupong) represent the back of the crab, the tattoos on the arms (ketam lengan) represent the arms of the crab. A crab's shell is a hard armor, which protects its wearer.
