Stingrays belong to a group of fish called Dasyatidae, which includes rays, sharks and skates, and all have skeletons made of cartilage. Rays often lie on the seabed, where their flat shape and coloring make them difficult to see. Some rays are harmless, but others will quickly attack if stepped on or disturbed. Stingrays are found in tropical, warm waters around the world. They get their name from the sharp spines that grow near the base of their long, thin tails, in which both are very dangerous weapons. If an enemy gets too close, the stingray whips its tail around and drives its spine into its victim’s body. The spine is coated with poison and imposes a tremendously painful, though rarely fatal, wound. Several swimmers have died after being stung in the stomach or chest by stingrays. Stingray spines were once used by local people as weapons and sometimes unfortunately sold as letter openers to tourists.
Portuguese Man O’War (Physalia Physalis)
Also known as the Bluebottle, this “jellyfish” is actually a siphonophore, an organism that is made up of hundreds of small marine organisms, mainly polyps. They mainly live in warm oceans all around the world. Their tentacles can trail up to 165 feet behind their bodies, but average length is about 50 feet. Their powerful sting causes a sharp burning pain to humans, but the Man O’War is rarely fatal. Some side effects from the organism may include fever, shock, and circulatory and respiratory problems. Seek first aid quickly and to help neutralize the venom, pour vinegar over the area of the sting. In certain cases, an allergic reaction may occur and they may need medical treatment at a hospital to treat the side effects and pain. There have been deaths of humans from this species, so be careful next time you go to the beach.
Sea Wasp (Chironex Fleckeri)
Also known as the box jellyfish, they are one of the deadliest creatures in the world. They have a large transparent body shaped like a box, which can weigh as much as two kilograms. Under the large body, millions of stinging capsules cover the 120-inch transparent tentacles that are deadly to humans. These creatures mainly live in the Australian seas and as they move to creeks and rivers, many swimmers can be stung. Children who are stung die within minutes of being stung. Symptoms includes a shock in the heart, complete circulatory failure, and the respiratory system paralyzes. If these symptoms are not treated quickly, the victim can die in two or three minutes, even if they are an adult.
