Sea urchin injury
Sea urchin injury on the top side of the foot. This injury resulted in some skin staining from the natural purple-black dye of the urchin.
Sea urchin injuries are caused by contact with sea urchins, and are characterized by puncture wounds inflicted by the animal's brittle, fragile spines.[1]: 431
Process[]
Sea urchin spines can be venomous or cause infection. Granuloma and staining of the skin from the natural dye inside the sea urchin can also occur. Breathing problems may indicate a serious reaction to toxins in the sea urchin.[2]
Following injury by a non-venomous sea urchin, the spine can stay for a while inside the flesh, causing pain and discomfort. The spines dissolve after a time, or are expelled from the body.[citation needed]
