It was a rare red flag warning at Blanes beach, in Sant Francesc, last Monday because a number of rays had been seen in the water.
They do not normally attack people, but when a ray is accidentally stepped on, the fish defends itself with its tail, which includes one or more barbed stingers, causing extremely painful injuries. With their flattened appearance, the fish are difficult to spot even in shallow water.
A total of five rays were observed in the water. The fish, which measure 40 inches wide by 40 inches long and with a 20-inch tail, are smaller than varieties found elsewhere, says the Institute of Marine Sciences.
Although extremely painful, the stings of this particular variety are not poisonous, biologists at the Institute say. However, the lifeguards, employed by the Civil Protection department, will prohibit people from getting into the water when the fish are seen. The red flag warning remained in effect until the following morning.
If you're worried about stingrays, which are almost never seen near the Blanes coast, shuffle around instead of wading in the water. Alternatively, throw some rocks into the water to chase them away. As always, when going to the sea it may also be advisable to wear wet shoes.
Stings from the stingray should be treated by a doctor, who will usually administer a tetanus shot. Until then, if possible, keep the injured area in warm water and apply a pressure bandage if the wound is bleeding.
