Things that sting… and how to avoid them!
By Gemma Smith
Here be Dragons warned medieval maps, as land gave way to uncharted oceans and their mysterious inhabitants. Well, as it turns out there are dragons in the seas, but they are small and loveable (Phyllopteryx taeniolatus). No threat at all! There are however creatures who can give divers, snorkelers, swimmers and surfers painful and, at times, fatal stings. Here are some of them to look out for… but remember, these animals are only defending themselves or trying to catch their dinner!
Stingray
The death of Australian naturalist Steve Irwin from a stingray made international headlines in 2006. Yet it was only the second recorded stingray-induced death in Australian waters since 1945. Stingrays are not naturally aggressive but like any animal will react if frightened. Often hiding in sand to await prey, the ‘stingray shuffle’ (sliding your feet along the sand rather than stepping down hard) can alert the animals to your presence and allow them to take avoiding action.
Stingrays are common in coastal tropical and subtropical marine waters throughout the world. Some species live in the deep ocean, and there are also river stingrays. They have a venomous barb on the end of their tail which they use for defense
Stingray injuries are rarely fatal. In Steve Irwin’s infamous case, the stinger penetrated his chest cavity causing massive trauma. Nonetheless, stings are serious. They can cause pain, bleeding, nausea, weakness, and fainting. Embedded spines are best left to medical professionals to remove. This is in case the barb breaks off in the wound, which may lead to infection.
First aid includes cleaning the wound and immersing the injury in hot (40° C/104° F) water if possible for at least 30 minutes. Remember: Always seek medical attention for a stingray sting.
Weever Fish
This small fish which rests in sandy shallows near the shore punches, literally, above its weight! Its toxic dorsal spines produce acute pain if stepped on. Other symptoms are nausea, headache, and even abdominal cramps. Death is extremely rare.
As with other such injuries don’t remove embedded spines with bare hands. Always wear gloves or use tweezers! To reduce pain, immerse the foot in hot water (as above with stingray injuries). These small but potent fish live in the coastal waters of the Atlantic, North Sea, and the Mediterranean.
Jellyfish
These sea creatures have tentacles covered with individual stingers called nematocysts. Jellyfish generally fire their darts into prey, but swimmers, divers, and snorkelers can be stung by physical contact. Swarms of jellyfish can also wash up on beaches.
in January 2019 about 13,000 stings were recorded on Queensland beaches from a massive influx of bluebottle jellyfish!
In May 2017 more than 300 Barrel jellyfish washed up on a beach in Wales.
So long as the stinger in the animals is still hydrated it can fire off into unsuspecting beachcombers who touch the animals. Always remove any tentacles using gloves or tweezers and, to reduce pain, immerse the affected area in hot water.
Most stings from jellyfish cause rashes and/or blisters. More acute reactions can be headaches or even chest pain. But stings from the Australian Box jellyfish and the Portuguese Man-of-War can be fatal. These need immediate emergency medical attention.
Be prepared to perform CPR in case of respiratory failure. Sea Wasp stings may prove fatal in as little as three minutes. To be safe, do your research before diving: avoid known Box Jellyfish habitats and minimize the amount of uncovered skin.
Blue-Ringed Octopus
This small (12-20 cm/5-8 in) shy little octopus with its distinctive blue rings has enough venom to paralyze ten adult humans according to a University of Sydney study. Found in tide pools and coral reefs in the Pacific and Indian Oceans, it spends much of its time hiding in small crevices or abandoned shells.
If threatened, its bite is tiny and relatively painless. The venom however can cause tingling of the lips and tongue, followed by difficulty swallowing, dizziness, and headache. This can progress to paralysis and eventual respiratory distress or failure. The victim is aware something is wrong but can do nothing.
If bitten by a Blue-ringed octopus always seek medical attention. First aid is pressure on the wound (‘pressure immobilization technique’) and artificial respiration (CPR) if there are signs of respiratory failure. Hospital treatment consists of putting the victim on a medical ventilator until the patient’s own system can metabolize and secrete the venom. Luckily there are few reported deaths. With timely medical help, full recovery is the norm.
Cone snails
There are about 600 species of cone snail. They can be found in the Indian and Pacific Oceans, the Caribbean and the Red Sea. They live in reefs hiding themselves partially under sandy sediments. They often have beautifully patterned shells, very attractive to collectors.
All cone snails are poisonous to some degree. It is only the larger ones, up to 23 cm/9 in long, which we need to worry about. Every snail has a venom-injecting ‘tooth’; someone picks up a cone snail it responds by ‘biting’ the offender with its harpoon-like tooth.
In the case of the larger snails this tooth can sometimes penetrate gloves or wetsuits. This ‘bite’ can cause mild to moderate pain. In more serious instances numbness, blurred visions and paralysis can occur. Paralysis can sometimes lead to respiratory failure. Symptoms can appear immediately or may take a few days.
Always seek medical attention in case of a cone snail sting. First aid measures can include application of heat (such as soaking the affected area in hot water) for pain relief. Also use of the ‘pressure immobilization technique’ can help slow progression of the toxin. Watch out for symptoms appearing in succeeding days.
Finally
These marine creatures are not generally aggressive but will react if frightened, so some general rules:
- Don’t touch them. Even dead jellyfish can sting!
- Be careful where you put your hands; someone may be lurking under a rock or in a crevice or an abandoned sea shell.
- If walking in shallow water do the ‘stingray shuffle’! This gives anything hidden in the sand time to get out of the way. After all, they don’t want to waste their venom on you!
- The use of vinegar on a sting is controversial but recent research from the University of Hawaii on Man of War stings has shown that rinsing the area with household vinegar can halt discharge of more venom.
- Don’t pee on a sting. It doesn’t help!
- Don’t touch spines with bare hands
- Gently clean the wound but don’t scrub, close, or cover it
- Remember the pressure immobilization technique, and use if recommended (see below)
- Always seek medical advice if there is evidence of chest pain, difficulty in breathing or numbness, or if you are in any way concerned about the injury. Minor injuries might mask a bigger problem. Better safe than sorry!
Pressure Immobilization Technique
This technique was developed in the 1970s by an Australian medical researcher, Struan Sutherland. It was originally designed to be used on certain snake and spider bite injuries. Its purpose is to contain the spread of venom from the affected area, and prevent the venom circulating to reach the vital organs.
It is not suitable for all bites/stings whether for snakes, spiders or other creatures. It is recommended for blue-ringed octopus bites and cone snail stings. Check DAN or another reputable site to refresh your memory if diving in waters where you are likely to meet these creatures.
The procedure is generally to:
- Use an elasticated bandage, if available, to wrap the affected limb and apply firm pressure. Clothing such as a long-sleeved shirt or pantyhose can be used if nothing else is available.
- Begin by bandaging a couple of inches above the bite site and then downwards over and past the bite site to the hand or foot.
- The bandage should be snug but should not impede blood circulation.
- The limb must be kept as immobile as possible as movement will encourage blood flow.
- Splint the limb if possible or use a sling on upper limbs to further immobilize the patient.
- Above all, seek medical help!
These are a few of the problems you may encounter while diving, snorkeling, or other water-based activities. It is important to always keep your First Aid knowledge up to date, and to carry basic First Aid equipment whenever you dive. Remember, the oceans are a marvelous place full of amazing and unique creatures. Respect them, and your visits to their world will be a delight and not a disaster.

Are you ready to become a Cave Diver?
By Marissa Eckert
What are the requirements to start cave diving? What do I need to do to be prepared for cave training? These are all questions I get asked by so many potential students. There are many options when coming up with an answer. The first option, and the easiest, would be to go the training agency website and look up the requirements to take the class. However, this leaves a lot open for interpretation and doesn’t mean you will necessarily be ready. Like anything, there always needs to be minimum requirements. But is that enough? Maybe for some people it is, but for most people it’s not.
So, what are the requirements?
TDI breaks cave training down into three different levels. Those levels are cavern, intro to cave, and full cave. To start cavern the requirements state that you must be 18 years old or 15 years old with parental consent, have an Open Water Certification, and a minimum of 25 logged dives. This doesn’t sound like much. So, what do I tell my students when they ask me? First, I find out if they are only interested in cavern or if they are interested in potentially progressing into cave diving. If they are interested in progressing into cave diving, I always strongly suggest they get comfortable with a dual configuration first. This configuration can be side mount, back-mounted doubles, or even a rebreather. The main things I tell everyone they need to have down are buoyancy, good trim position, the ability to hover in place motionless without moving their hands or feet, and good overall awareness. This means awareness of oneself and what your body and equipment are doing, but also total awareness of what is going on around you.
So, what does all this mean?
Many times I’ve had students show up thinking they had all these things mastered only to quickly realize they have a long way to go. Which by the way, is okay! After all, we all start somewhere and progress at different paces. The most important thing is to be open to feedback. But there are also ways to prepare yourself better. First and foremost, when starting down this route it is critical to find a good instructor. Take time to look up instructors, ask questions, interview them, look at their past students, look at what type of diving they are doing, and most importantly ask questions! Find out what techniques they use during class.
I have found that video recording students when they are struggling with something gives them a great perspective to see what they are doing wrong and helps them visualize and correct it. Does the instructor look good as a diver? Whether you like social media or not, the internet can be a great place for research. When looking at a diver they should look in trim, almost like they are laying flat on a table. In videos are they finning with their hands? Are their feet constantly moving? Are there things dangling below their body? All equipment and hoses should be extremely clean and contoured to the body.
The most important question to always ask during training is WHY? There should always be a why behind everything we do. And it should never just be because I said so. Make sure the instructor knows why they are telling you to do something a particular way. Everyone can always learn new ways of doing things, instructors included.
How can you truly prepare yourself?
A good idea is to record video of yourself or have a friend record you while diving. Send it to your instructor ahead of time, so they can give you feedback and let you know if there are things you need to work on. There is no certain number of years to be diving, or a certain number of dives to have, that says yes you will be ready. Every individual learns at a different pace. If a class is only offered in a minimum number of days with a maximum number of students allowed, be aware that this means less time practicing each skill. For this reason, you might be better suited doing one-on-one training or having a regular buddy take the class with you. This ensures you are comfortable with each other and familiar with each other’s habits in and out of the water, and that you get along!
The most important thing of all is to come to class with an open mind, a readiness to learn, and no concern with whether you will receive a card, but with a concern that you will learn to be a better, safer, more competent diver. I always tell my students safety is the number one most important thing in cave diving, but fun is a close second! Sometimes, it may not feel fun. Stop and ask yourself does this instructor have your best interests at heart? I know I certainly do. I want to go to sleep each night knowing that I gave my students as much knowledge as possible to make them safe and thoughtful cave divers.
With proper training, proper equipment, proper experience, and a proper attitude I think cave diving can be done very safely. I often joke that the most dangerous thing about cave diving is driving to the dive site!
