When the Man o War is the Blue Bottle…

While the Portuguese Man o War is easily recognized for its distinctive color and partially filled bladder, its first cousin, commonly referred to regionally as the Blue Bottle is found in the Indo-Pacific region from Australia north and east as far as the Hawaiian Islands.   This picture, courtesy of the Noah Project, shows the Blue Bottle beached in New South Wales, Australia..Lat: -35.83, Long: 150.22 Spotted by George T on Dec 17, 2011

The bluebottle Physalia utriculus is Australia’s most common species.  The bluebottle is found in vast numbers on the eastern Australian coast every year. They also occur in South and Western Australia. The sting causes immediate pain which can last more than an hour. The pain is usually in the lymph glands draining the arms and legs.

If you get stung, use the Ocean Care Man o War First Aid Kit..it’s all there for effective pain relief and first aid. Don’t get stung without it !!

 

Are Jellyfish Stings Dangerous?

The effects of jellyfish stings can range from mild pain and stinging, to skin irritations and blisters, to respiratory problems, cardiac arrest, and death. The toxicity of a jellyfish sting depends upon the species of jellyfish and the reaction of a person’s body to the jellyfish venom.

The most toxic type of jellyfish is the Box Jellyfish (Chironex fleckeri and Caruka barnesi) found in Australia and some regions of the Indo-Pacific. The venom of the Box Jellyfish has been known to kill a person in five minutes.

Box Jellyfish

Irukandji…no larger than your thumb nail but extremely venomous…

People react differently to jellyfish stings. Consider a jellyfish sting as a “dose” of poison. The smaller the person, the greater the effect of a jellyfish sting will be. Just as some people are highly allergic to bees and may go into anaphylactic shock from a single sting, other people may be unusually sensitive to jellyfish venom and may have a similar severe reaction.

OCS Jellyfish Sting Relief is very effective on the Box jelly..Our specially formulated 5 % acetic acid (stronger than household vinegar) has proven effective on the Box and a wide variety of jellies and marine stingers but we have not, nor ever plan to test our product on the Irukanji.  Just too dangerous even though we are told by The Marine Sting Institute, Queensland, through their own experience; 5% acetic acid application can relive the pain of the Irukandji but NOT the syndrome..Best to stay away from thse animals all together.

Take it along with you..it works !!!

Safely Dive With Stingrays…avoid the attack zone..

As they gently glide a few inches above the sand, stingrays appear elegant, peaceful and calm – and they are ninety-nine percent of the time. The only time divers need to worry is when stingrays feel endangered. A frightened sting ray can plunge its sharp, venomous sting straight through a wetsuit and deep into a diver’s flesh.
While diving, stingrays may be approached with little risk. On the rare occasion that a stingray strikes a diver underwater, the diver has most likely inadvertently threatened or cornered the animal. Perhaps the diver hovered directly over the ray or floated in front of it making the stingray feel trapped against a reef without an escape route.
Because a stingray sees and swims forward easily, leave it a forward escape route. Most importantly, stay out a stingray’s striking zone, the area directly above the ray. The ray can easily strike in the area at the top of its back by arching its tail forward. By contrast, the area behind the ray’s back and the space to its sides are difficult for the ray to reach without turning its body or making swimming adjustments. Divers who are alert and aware of the stingray’s attack zone should be relatively safe.

Stingray attacks are more likely to occur to divers who are entering or exiting the ocean through shallow water and accidentally step on a stingray. Naturally the stingray will react. When the stingray is stepped on, it quickly whips its long tail forward and down, which jabs the sting at the base of the tail into the offender. This is a defensive maneuver designed to remove the diver’s foot from the stingray’s body, and it works. To avoid stepping on top of a stingray, divers can shuffle their feet when entering or exiting the water. In addition, divers should be aware of stingray habitats such as long sandy shores. Because neither dive booties nor fins protect a diver from a stingray’s hard, razor sharp sting, the diver should be vigilant if he suspects he might be in a stingray habitat.

Although the possibilities of being stung are in yiour favor, take along our Ocean Care Stingray First Aid Kit.  Everything is there to provide you immediate first aid with easy to follow directions on just what to do..Don’t get stung with out  !!

Most fire coral frequently has white tips…

Fire coral grows in familiar coral shapes. Divers have reported seeing fire coral in blade, branching, box, and even encrusting forms. As fire coral is easily confused with other corals, color is a good way to identify it. Most fire coral is a brownish-orange or brownish-green. It frequently has white tips, like the fire coral in this photo.

But if you do have an encounter with stinging fire coral, use our Ocean Care Fire Coral First Aid Kit…everything you need is in the bag..air tight, convenient to use and effective !! Don’t going diving without it !!

Fire Coral..beautiful but dangerous..

Don’t learn about fire coral the hard way. Fire coral is related to jellyfish and anemones, and just like these creatures, it can really, really, sting. This Fire coral, Millepora sp., is beautiful, but dangerous.


Learn to identify fire coral and then be sure to avoid it! Divers should be on the look out for fire coral in tropical and subtropical seas. But if you do have an encounter with stinging fire coral, use our Ocean Care Fire Coral First Aid Kit…everything you need is in the bag..air tight, convenient to use and effective !!

Lion's Mane Jellyfish..a giant among jellyfish

Lion’s Mane Jellyfish

Image:  Dan Hershman via flickr
The lion’s mane jellyfish is a giant among jellyfish. In fact it’s the giantest of all jellyfish yet known, even if ‘giantest’ isn’t a word. They are found only in the northern hemisphere. Actually they’re found only in the northern half of the northern hemisphere, right up into the freezing waters of the Arctic. They really, really like cold water.
Lion’s mane jellyfish come in a wide variety of sizes depending on how far north they are. Those that approach the warmest waters they tolerate, around half way to the equator, are smaller and a pale orange colour. The wobbly jelly body, known as the bell, may be a mere 50 centimetres in diameter. Pff, whatever.
As we move north into colder waters, we find the lion’s mane getting darker in colour and bigger in size. Eventually they become the monstrosities we really want to see (from a safe distance) – dark crimson with a bell up to 2.5 metres (8 feet) across and tentacles trailing 120 feet behind. That’s really long by the way. Longer even than the blue whale, the biggest animal to have ever lived. I’m guessing this ridiculous size is more about getting enough food in colder seas, rather than the jellyfish having a stretch in the cold or something.
Food for this creature is anything from tiny animal plankton to small fish and other jellyfish. The lion’s mane’s (seems odd to write that) bell is arranged into 8 lobes each with 60 to 130 tentacles, adding up to lots and lots of tentacles. Naturally, they sting. Thankfully, they are not lethal to humans. Hundreds of 100 foot tentacles… I think we got lucky there. The Lion’s Mane (and now I feel like going down the pub) also has a load of arms at the centre of the tentacles. They’re much shorter and help with actually getting food into it’s mouth. That could be quite a journey!
Interestingly, a whole host of little fish swim about with the lion’s mane, escaping death by tentacle and using them for protection instead. They can even pluck out bits of food before it reaches the jellyfish’s mouth. I don’t know if the lion’s mane jellyfish is capable of getting annoyed, but if it can, that would probably do it.

Bloodybelly Comb Jellfish..

The bloodybelly comb jellys sparkling display is from light diffracting from tiny transparent, hair-like cilia. These beat continuously as a form of propulsion. In the deep sea, the jelly is nearly invisible; animals that are red appear black and blend into the dark background.

Comb jellys are a kind of jelly thing that aren’t particularly closely related to jellyfish. They swim by beating their so called ‘combs’, which are actually hair-like structures called cilia. You can see rows of them  all along the animal shimmering and glittering in the gloom. They are carnivorous and have two sticky tentacles for capturing prey. This particular comb jelly has a deeply pigmented stomach for masking the bioluminescence of its food. It also looks a bit like a heart, before looking more like some foreboding alien space vessel. Spooky.

What is a Jellyfish ??

What Is a Jellyfish?

Portuguese Man-of-War

© Alex Edmonds | Dreamstime.com

The Portuguese man-of-war is not technically a jellyfish; at least it is not a “true” jellyfish. The man-of-war belongs to a large group of similar creatures (of the subphylum Medusozoa). This grouping is divided into four classes, but only one of them includes the true jellyfish.

The man-of-war is a Hydrozoa, which consists primarily of colonial creatures made of several zooids connected together.

True jellyfish are single organisms that belong to the class Scyphozoa, which includes moon (or common) jellyfish and lion’s mane jellyfish. They have stingers and two life phases like men-of-war, but their dome-shaped bodies display a beautiful four-part symmetry.

There are two other classes. The first, Cubozoa, are square-shaped creatures known for their extremely potent venom, like the Irukandji jellyfish and box jellies (also known as sea wasps). Staurozoa, the second, have unique life cycles and live out their days attached to the seafloor. They look more like sea anemones than jellyfish.
