In the last list of marine creatures to be aware of, we talked about sharks, sea urchins, box jellyfish, sea snakes and stingrays. Those were already a handful and so I saved up the rest of the list for this entry.
The importance of this is to be aware of what creatures you’ll encounter when you’re scuba diving, why they are dangerous and how you can avoid them or treat the damage they can cause you.
So without further ado, here’s the rest of the dangerous marine creatures:
Puffer Fish – If only this fish was as kind as Bloat in Finding Nemo, but it’s not. This fish is known to contain enough toxin that it can kill 30 people. The sad fact about it is that there is no known antidote, what one can only do is support the respiratory and circulatory system until the poison wears off.
What’s very ironic is that this fish is considered a delicacy in Japan, so if you have a loved one that’s been a victim of this fish, go ahead and eat one for revenge.
Stonefish – This fish is known to be the most poisonous fish in the world. It’s also good in camouflage that people accidentally get too close to it. This fish has 13 spikes on its back that contains an extreme venom. If not treated, it can cause death to a person in hours. Be aware of this fish because not only is it good in camouflage looking like rocks but it usually hides in coral reefs and can be found at the sea bottom.

Whoops! Wrong picture

Got it right
Catfish – No matter how good they taste and how crispy they can get, these fishes can be a potential danger to humans. When it feels threatened, it puts out spikes that contain venom and cause severe pain. Though very rare, there have been cases that death has been caused by such. Catfish venom still remains in them after a few days, so if you’re planning to cook one, be aware and cautious and handle it with care.
Blue Ring Octopus – Though these creatures are small, they are known to be the deadliest sea creatures ever known. They will attack anything, even humans, when provoked. Their poison is enough to kill 20 people or more in minutes. Their venom can cause paralysis and respiratory arrest. Again, there is no known cure for it.
Cone Shell – No matter how attractive these may be, be careful before you pick them up. These are snails that have teeth like harpoons where venom passes through. Such venom’s symptoms are pain, swelling and numbness and, in some cases, can lead to death.
Lionfish – These fishes have long poisonous spines that are deadly to a variety of marine creatures. Though not known to be deadly to man, it causes severe pain, headaches and vomiting. They don’t attack people unless provoked but if you get stung by one, soak the affected area in hot water and immediately get medical help.
These are some of very dangerous marine creatures known to man, but we should always remember that we are more dominant than them because we have the brains to keep ourselves safe.
Always remember to be alert and cautious. Seek medical help immediately when needed. Never, ever provoke such animals because most of the ones listed here will only attack when they are provoked.
Shark – The most common of all sea animals that people dread. But if you want to be more specific, it’s the Great White Shark that’s truly feared. (Don’t know the Great White Shark? Refer to JAWS) But what we humans aren’t really aware of is that sharks don’t really attack people, unless provoked.
Sea Urchins – The usual “attack” from a sea urchin is where one walks in water and steps on one. It’s good to know that almost all sea urchins are not venomous except for one – the Flower Urchin, which can be deadly.
Box Jellyfish –
Sea Snakes – These snakes are usually found in warm waters. They usually attack when provoked. These snakes are very venomous and if not treated immediately can cause cardiac arrest in hours. Their bites usually go unnoticed, that’s why always be alarmed. Sea snakes are usually found in shallow waters wherein they are still close to land.
Stingrays – Nobody was really aware how dangerous these creatures were until the sad death of the famous Steve Irwin. These creatures normally run away when they sense humans but attacks when provoked. The best tip for humans is to slide their feet through the sand rather than walk because once you step on a stingray, it will ferociously attack you.







Have you ever heard about “the Asian Trash Trail”, “the Trash Vortex” or also called the “the Plastic Ocean”? These are terms for a heap of debris, compressed by the oceans currents, floating in the Pacific with twice the size of Texas.
- About 44% of all seabirds eat plastic, apparently by mistake, most of the times with fatal effects.
marine life suffers and an even bigger marine population dies. And as we are the last in the food chain, we are definitely experiencing the consequences of our actions.
them as best as we can. Our company provides drinking water from dispensers, we also try our best to convince our customers to refill their bottles and recycle plastic bottles on all our boats – because we care. And I care! Therefore I’m sending out information again and again, that’s why I’m posting links as much as possible and that’s the reason why, every time I drink up a bottle of water, I take my own cotton shopping bag and make sure I throw my trash at the right place.
