I’m on my way to get some sun…



We are excited to welcome The Diver Medic’s Chantelle Newman to Scubaverse. Chantelle will be writing about health and medical matters for Scubaverse readers… in her first post, some important travel advice!

Are you thinking of travelling soon? Are you prepared? Do you have your travel arrangements? Do you know what vaccinations you need? Will you require anti-malarial prophylactic medications, for example, especially in tropical, sub-tropical regions of the World? Perhaps certain antibiotics, which will protect you and treat traveller’s diarrhoea, also known as ‘Montezuma’s Revenge’ when travelling to Mexico and Central America.

Eating & Drinking

Water and food-borne illnesses are particularly burdensome to divers and water sports enthusiasts, and these are often preventable, with just a few simple precautions – such as anything consumed orally. Start by ensuring that hot foods are hot and consumed as soon as possible after cooking. Cold foods should be cold and consumed right after removal from proper refrigeration, especially in the tropics.

Remember that ice cubes may be frozen using contaminated water, in regions of the World lacking chlorination. These present the risk of melting into your frozen cocktail, at the Tiki bar on the beach, thereby releasing germs into your exotic libation when the ice cubes melt.

Even though your drink and container may have been handled in a perfectly exemplary sanitary manner by your waiter, remember always to use a straw, which you have un-wrapped yourself, for sipping those drinks. It’s also advisable to avoid contact with the edge of any glass directly with your lips and mouth in order to prevent hepatitis and notwithstanding when everything else goes well, NEVER DRINK (Alcohol) & DIVE!

Food ought to be served in covered dishes, to prevent access to insects and other bugs and / or parasites. It is safer and more advisable to use sealed and sanitized eating utensils, which you have opened yourself. After your personal use, recycle, thus presenting a perfect teachable moment in countries which do not re-cycle plastic. Share the valuable information of not discarding rubbish, especially non-biodegradable plastics into the Oceans and waterways, consequently helping to save our fragile and precious seas.

Common Sense Guidelines

Avoid walking barefoot on the beach or along the margins of dense vegetation near the beach. The possibility of direct contact of the soles of your feet with the urinary and fecal remnants of rodents and other exotic vermin can produce conditions such as  Leptospirosis, Cutaneous Larva migrans; whilst a large variety of terrestrial and marine organisms may lead to a broad variety of skin rashes, both pigmented and raised, accompanied by swollen lymph glands, fever, and sometimes even more serious generalized medical syndromes and illnesses.

Even so, do not let all of this dissuade you from enjoying your holiday! As long as you follow some basic precautions and common sense guidelines, you have every prospect of experiencing a fabulous vacation and dive trip to a safe region of the Globe, with access to knowledgeable medical personnel.

Just think…it is possible to contract a grave and intractable medical condition from staying home and simply working improperly on your Aquarium with un-gloved hands. Fish-Handler’s Granuloma – caused by a serious germ – Mycobacterium Marinum, may take weeks or months to manifest itself and requires months of medical and surgical care presuming it is properly recognized, evaluated, and dealt with…

Travelling can be exciting but also stressful for some of us, even before we get to go on holiday. Going to another country may be very daunting. Have you packed everything you need? Here is a little help!

What to pack? 

Sunscreen – attempt to purchase sunscreen that is labelled “broad spectrum” as this means it protects you against both UVB and UVA rays. Ensure you get sunscreen with a sun protector factor (SPF) of at least 20.

Insect Repellent – research has shown that products that contain the chemical DEET (N, N- Diethyl-meta-toluamide) are the most effective insect repellents against mosquitoes, ticks, fleas, harvest mites and many other bugs if used correctly. DEET products can be applied onto clothing and skin and are available in sprays, sticks, roll-ons and creams. 100% DEET when applied can be effective up to 12 hours. When using DEET on your skin for the first time, try to use a very small amount, around the size of the tip of your little finger and leave for 5 to 15 minutes. If you develop redness, blisters or itching, then seek medical advice on what other products you can use as you may have a DEET allergy.

Anti-Diarrhoea pills – Traveller’s diarrhoea is the most common illness affecting travellers. Diarrhoea is when there are three or more unformed stools in 24 hours passed by a traveller, accompanied by nausea, bloating and abdominal cramps. Traveller’s diarrhoea is more common in the developing world, where rates exceed 60% compared to advanced countries. A drug used to relieve the symptom is loperamide but it should not be overused. In most countries, it is available generically and under brand names such as Lopex, Dimor, Fortasec, Lopedium, Gastro-Stop, Pepto Diarrhoea Control, Imodium and Lomotil.

Ensure you read the label of any drug before use. Do not take anti-diarrhoea drugs if there is blood in your stools, or if you have a high temperature (check with your pharmacist). Do not give anti-diarrhoea drugs to your child, seek medical advice first. Anti-spasmodics, which are used to treat abdominal cramps ought to be avoided as well as pharmaceuticals such as Motilium – these have recently been removed from the market in many but perhaps not ALL countries and therefore, you are well advised to seek qualified medical assistance, evaluation and treatment.

Rehydration sachets – most travel clinics advise travellers to carry rehydration sachets when travelling in developing countries. As safeguarding, it will not harm you to add some sachets in with your travel kit. Rehydration sachets contain rehydration salts consisting of sugars and salts (anhydrous glucose, sodium chloride, potassium chloride and sodium bicarbonate). They are used to replace body fluids lost as a result of acute diarrhoea.

Anti-malarial drugs  Anti-malaria medications, also known as antimalarials, are designed to prevent or cure malaria. Mosquitoes may cause an inconvenience because of local reactions to the bites themselves and from the infections they transmit. Mosquitoes spread malaria, yellow fever, dengue and Japanese encephalitis. Remember Garlic, Vitamin B and ultrasound devices do not prevent bites. Recommendations for drugs to prevent malaria differ by country of travel and can be found in the country-specific tables of the Yellow Book.

Recommended drugs for each country are listed in alphabetical order and have comparable efficacy in that country. See this link for more information on the country you may be travelling too: 

Antihistamines  Antihistamines are mainly used to treat hay fever (seasonal allergic rhinitis), hives (urticaria), itching (pruritus) and insect bites and stings. They may be used to help reduce feeling sick (nausea) and vomiting. Antihistamines are available as tablets (oral antihistamines), creams (topical antihistamines) and nasal sprays. They work by blocking the effects of a protein called histamine. Many antihistamines are available over the counter at a pharmacy, although some require a prescription. Here are some brands of antihistamines: Atarax, Benadryl, Clarinex, Dramamine, Optimine, Quenalin, Zyrtec, Cinnarizine and Piriton. Some antihistamines cause drowsiness, and once again, excessive alcohol use ought to be avoided.

Diabetics should arrange for an adequate supply of materials and equipment, for blood sugar testing because travellers are likely to experience inordinate delays in obtaining authorized access to such supplies in most countries and ought to bring their own lancets, test strips, Glucometers etc.

Contracting Airborne diseases can be minimized by use of tight N-95 masks, which are the recommended barrier method, particularly on long international flights with prolonged exposure to re-circulated air in the aircraft cabin, which places air travellers at risks for inhalation of particulate droplet spread of viruses and other organisms.

Pain relief medication – Pain is a signal from our body that something is not right. It can be due to a physical injury or some kind of illness. Most types of physical pain can be treated with pain relievers. Over-the-counter medications are good for many types of pain. Analgesics (pain relief) such as acetaminophen (Tylenol) or paracetamol are used to treat mild or moderate pain and can also be used to reduce temperature in fevers. Commonly prescribed medication such as codeine can be used alone or in combination with other analgesics for stronger pain, such as dental pain, menstrual pain or migraines. Non-steroidal anti-inflammatory drugs (including aspirin) are used to reduce pain associated with inflammation, such as sports injuries, and can also be used to relieve fever. Always seek medical advice before taking any off the shelf medication. What a lot of people do not realise is that their prescribed medication may not be suitably compatible when being used with certain over the counter medication and may cause serious health issues.  

First-Aid Kit – The Lifesystems World Traveller Kit is a very comprehensive first-aid kit and has the following items included in the kit: Primary Care Leaflet, Fabric Plasters, Woven Bandage, Crepe Bandage, Triangular Bandage, Gauze Swabs, Paracetamol, Loperamide, Ibuprofen, Low Adherent Dressing, Medium Dressing, Eye pad Dressing, Fabric Dressing Strip, Wound Closure Strips, Zinc Oxide Tape, Micropore Tape, Duct Tape, Scalpel, Hypodermic Needles & Syringes, Forehead Thermometer, Antiseptic Wipes, Scissors, Tweezers, Safety Pins, Powder Free Vinyl Gloves. The Lifesystems Traveller Kit is the basic kit without the Needles and Syringes. However, going to your local supermarket or pharmacy you can make your own kit up with the list provided. Check out some first-aid kits and travel product available by going to and for the US and Canada

You might want to add products for marine life injuries such as 5% Acetic acid (Vinegar is roughly 4%-8% acetic acid by volume) for Jelly fish stings. Unfortunately, in the real world treating a jellyfish sting by urinating on it may, in fact, cause someone even more pain, rather than relief. Urine can, in reality, aggravate the jellyfish’s stingers into releasing more venom. Another item that may help is a heat pack. In the event you don’t have hot water on hand using a heat pack stored in your first-aid kit will help relieve some pain from a Stingray or Stonefish injury. Ultimately water heated up to a temperature of 40 to 50C but limiting the contact to prevent scalding burns, is the best treatment for Sea urchins, Devil, Scorpion, Stone fish and Stingrays.

Certain marine venoms and toxins, may be treated with anti-venoms, which may not be available everywhere. Australia and the Great Barrier Reef coastal regions have some of the best and most experienced and skilled emergency rescue personnel as well as doctors, nurses and medics, who implement standardised protocols for rapid triage, evacuation and possible expedient treatment including hyperbaric oxygen therapy for Scuba Divers suffering from a variety of medical conditions associated with diving.

Travel Insurance – this is the most important product when travelling, never leave home without it! What travel insurance does, of course, is to prevent you from financial disaster if something actually does go wrong. There might be rare cases where someone without insurance gets air-lifted out at sea, but without insurance your costs for possible repatriation may cause you to have to re-mortgage your house… but honestly, your chances of being killed by a falling coconut are probably greater in the long run.

Travel safe always!

Diving with Frogfish in Costa Rica: A Hidden Gem Underwater




In the vast and vibrant underwater world of Costa Rica, there’s a peculiar creature that often goes unnoticed but holds a special place in the hearts of divers: the frogfish. This enigmatic and somewhat odd-looking species is a master of camouflage and a marvel of marine life. Diving with frogfish in Costa Rica is not just a dive; it’s an adventurous treasure hunt that rewards the patient and observant with unforgettable encounters. Let’s dive into the world of frogfish and discover what makes these creatures so fascinating and where you can find them in Costa Rica.

The Mystique of Frogfish

Frogfish belong to the family Antennariidae, a group of marine fish known for their incredible ability to blend into their surroundings. They can be found in a variety of colors, including yellow, pink, red, green, black, and white, and they often have unique spots and textures that mimic the coral and sponges around them. This camouflage isn’t just for show; it’s a critical survival tactic that helps them ambush prey and avoid predators.

One of the most remarkable features of the frogfish is its modified dorsal fin, which has evolved into a luring appendage called an esca. The frogfish uses this esca to mimic prey, such as small fish or crustaceans, enticing unsuspecting victims close enough to be engulfed by its surprisingly large mouth in a fraction of a second. This method of hunting is a fascinating spectacle that few divers forget once witnessed.

Where to Find Frogfish in Costa Rica

Costa Rica’s Pacific coast is dotted with dive sites that offer the chance to encounter these intriguing creatures. Bat Islands (Islas Murciélagos), Catalina Islands (Islas Catalinas), and the area around the Gulf of Papagayo are renowned for their rich marine life, including frogfish. These sites vary in depth and conditions, catering to both novice and experienced divers.

The key to spotting frogfish is to dive with a knowledgeable guide who can point out these master camouflagers hiding in plain sight. They’re often found perched on rocky outcroppings, nestled within coral, or even hiding among debris, perfectly mimicking their surroundings.


Diving Tips for Spotting Frogfish

Go Slow: The secret to spotting frogfish is to move slowly and scan carefully. Their camouflage is so effective that they can be right in front of you without being noticed.

Look for Details: Pay attention to the small details. A slightly different texture or an out-of-place color can be the clue you need.

Dive with Local Experts: Local dive guides have an eagle eye for spotting wildlife, including frogfish. Their expertise can significantly increase your chances of an encounter.

Practice Buoyancy Control: Good buoyancy control is essential not just for safety and coral preservation but also for getting a closer look without disturbing these delicate creatures.

Be Patient: Patience is key. Frogfish aren’t known for their speed, and sometimes staying in one spot and observing can yield the best sightings.

Conservation and Respect

While the excitement of spotting a frogfish can be thrilling, it’s crucial to approach all marine life with respect and care. Maintain a safe distance, resist the urge to touch or provoke, and take only photos, leaving behind nothing but bubbles. Remember, the health of the reef and its inhabitants ensures future divers can enjoy these incredible encounters as much as you do.
