They will not attack humans but they will defend themselves when threatened, especially when stepped on (Figure 1). Stingrays cause around 1,500 injuries per year and are caused by puncture from their strong serrated, boney spines or barbs. The tail contains a sheath that will discharge venom once it is ruptured (Figure 2). If you are stung by a stingray, clean the injury with soap and water. Make sure the spine is completely removed and use hot water (45°C or 110°F) in order to decrease the pain caused by the poison (Figure 3). Venom from the stingray is thermolabile, which means that it will decompose with heat. The foot or leg is the most common area affected by these injuries due to stepping on the stingray which causes the tail to be thrust upward and forward. Effects of the venom include constriction of the blood vessels and tissue necrosis. The patient will feel extreme pain and may experience edema and swelling (Figure 4). Sometimes a fragment from the barb may be stuck inside the wound and this may cause an infection.
