Zebra Shark (Stegostoma fasciatum) is an Endangered species worldwide! Often mixed up with the Leopard Shark due to its Pattern. It’s called Zebra shark because as a juvenile it does have the black and white stripes of a zebra. This Zebra #Shark is 2,5m in length and is nocturnal laying on sandy patches and the seafloor during daytime. Unlike a Media lie that “all sharks have to swim” here is proof that many Sharks don’t have to. The zebra shark is oviparous which means the female lays eggs.

On a scuba dive at the Marine national Park Phi Phi Islands on 20th August 2015 we have found an illegal set Fishing Cage. A Lot of fish have been trapped inside and it was attached with a big rope to a Coral, either by scuba or surface supply divers! Fish cages are not allowed 3 nautical miles around the MN-Park Borders! Thanks a lot to Stefan Heinsen for the great Camera work and Anett for helping out! Also a big thank you goes to project abroad research divers!
Thats how a Frogfish walks (swims)

Because we humans burn fossils so fast the CO2 level in the Oceans rise Anemones become acid and Nemo has problems to locate predators.
According to numerous studies, if ocean acidification continues at the current rate, clownfish could experience significant sensory impairment. Since clownfish rely on their auditory and olfactory capabilities to evade predators and locate appropriate habitats, there is much indication that ocean acidification will negatively affect their population numbers. Signs appearing here! 6 years ago we had many more anemones and Nemos here!
PLEASE reduce your carbon footprint!
Here comes the Movie of our 2nd CleanUp day at Phi Phi Islands. Project Abroad and Poseidon Dive Center as well as many other Organizations and divers joined forces again. a big THANKS to everyone! It was a great day but a SHOCKING result! Guess how many kilogram of rubbish we removed in 2 days……???
Amazing Marine life at the Phi Phi Islands National Marine Park! A huge school of Yellow tailed Snappers and in between juv. Barracudas! #scuba
We didn’t see the king Cruiser Wreck either cause too many Fish in our way! 😉
Nemo in real life!
Today we rescued about 60 starving Fish from dying in an abandoned Fish cage which was illegally set way inside the Marine National Park laying on Corals which were damaged as well! Fortunately we found it by chance cut it open and released the Fish!
It was so amazing when they were released it gave me big jiggle and it seemed like they said Thank you before they left!
A small Movie of it will follow soon!
When do People finally understand that a Reef is Millions of $$$ more worth alive then dead???
The Project Abroad & Poseidon Dive Center rescued a young Green Turtle from drowning in an abandoned and drifting Net at Phi Phi Islands. Poor fishing practices are mostly the reason.
If we carry on fishing like we do at the moment there is NO fish left in 2048 how old your kids will be by then or yourself?
Right did you look further?
We are 8 billion people in this world no stopping of having kids. In 10 year’s we will be 10 billion people, ever thought of how to feed them? 8 mio die per year because of starvation already.
If we mess with the oceans marine life, soon there is no life anymore
All life comes from the ocean, called evolution.
The End of the Line! watch it!
and it is exactly like this, I dive since 16 years and have a huge number of dives and it decreases by day.
So a lot of people ask me: why don’t we farm fish like pigs or cows?
Not a good idea either to farm fish because, what do fish eat?
Fish eat other fish and where is the Fish-food coming from?
To produce 1000 kg of tuna you need 3000 kg of food (other live fish) where do they come from?
They come from the open Ocean so calculate how long that lasts if you need 3 times the amount of what you get out!
Another part is that a lot of people do not know that 80% of all fish are monogamy so they look for one partner in their whole life and if one of them gets eaten or caught the other one will never reproduce and or die as well.
We kill 100 mio sharks per year, for their fins.
Per second around 3,6 sharks get killed and 0,94 get born.
We take them out more than 3 times faster than they can reproduce.
We need the sharks it’s a reef cleaner, it eats old and sick fish
If we don’t have a reef cleaner anymore we kill the reef cause corals get overgrown by slime alga.
Do you know how many % of Oxygen we have in our air?…..
See 90% of all people do not know!
21% O2 is in our Air
Where does it come from?
Trees most people say.
We would not have enough trees in this world to produce that amount of O2
75% of our earth surface is water.
How much O2 is getting produced by trees?
How much O2 do you need per Breath?
so there you go….do the math without the O2 production from our Ocean
Shall I tell you a good story in between?
We have a nudi branch here which only has to eat one time in its entire life.
it eats corals so perfectly off and plants it in its tentacles so they grow and give food nutrients salts and minerals to the nudi.
It’s called “Blue Dragon”!
They are so much more advanced under water than we are
I guess you love Dolphins right?
Another story made up by the medias cause in reality they are not as lovely!!!!
Just one example: an Orca (Killer Whale) is the biggest of the Dolphins Family.
Back to our Sharks.
Women often ask me…..can I go diving because I have my period…..do i attract sharks then?
I always say then….I hope so 😉
But actually it’s the opposite
Another common misunderstanding about Sharks we get told by the Medias.
Yes its true they can smell a drop of blood in 1 mio liter of water but they would never come close as long as it is human blood, they do not like it! What do you do if don’t like your food in your mouth?! You spit it out don’t you?
That’s why 8 of 9 attacked people survive. The shark just try’s and spits you out again
How many people get killed by cats?
300 per year…a tiger are a cat isn’t it?
9 people get attacked by a shark per year
More people get killed by a falling coconut
or a soda pop machine
and many more people get killed by starvation 8 mil to be exact no one cares!
Just amazing what TV and Medias do to us
On top of that
Corals can only cope with 32.2°C of Water temperature everything above that, they’ll get stressed and die! We had this 2 years ago 10% of all our corals are brown and dead. It comes back but very slowly
How fast does the fastest Plant on Land grow and what is it?
The Bamboo, it can grow up to 10 cm a day!
So how fast is the fastest growing Coral and which one is it?
The Staghorn Coral and it grows 1 cm a YEAR!
On top of that:
We humans produce such a huge amount of rubbish, per person about 2.2 kg every single day.
2.2 kg x 8billion people x 365 days = 5,8 billion tones of rubbish
We humans already throw 8.1 mio tons of rubbish in the oceans every year! There is more plastic in the water than plankton! Broken down to so small pieces that our eye can’t see it!
So eating Fish is healthy isn’t it? At least that’s what the Medias are telling us to do!
We need the Ocean it protects us!
We live in such abundance that we don’t see it anymore! So much food, water, electric…..etc. all the time.
So whats the solution to this?
- Buy fish once a week (not 5 times) from sustainable resources.
- Lower your own standards.
- Turn off the water while soaping under the shower.
- Turn off lights which are not needed.
- Leave your car at home and take a walk or a bicycle.
- Don’t go to the Gym by car and then sit on the bike.
- Do not throw your rubbish over board or on the side of the street.
What Poseidon Dive Center does:
i could cry everyday about us stupid humans but that aint help…what helps is this!
- Educating our divers and guests!
- We sell our Best of underwater pictures; from the income of the pictures sold we’ll build & protect artificial & natural reefs! www.dani-sasse.de Have a look and please support us!
- Artificial reefs are great because they not only protect the fish from fisher nets they also reproduce quicker as well as Corals can hook onto the artificial reef quiet easily. It’s maybe only a drop of cold water on a hot stone but at least
- Farmed Fish and Turtle release.
- Replanting of knocked over Corals by anchor or humans stand on them.
- Setting buoys so Boats not have to anchor anymore.
- Fighting for proper Fishing laws in the Marine National Park

Clown Trigger Fish @ work!
Award Winning Picture by Daniel Sasse
We fish 80.000.000 Tonnes / Year 22.000.000 Tonnes is caught by chance and gets back into the water dead!
80% of all Fish live Monogamy!
If we carry on Fishing like we do at the moment there is NO Fish left in the year 2048!
We kill 100.000.000+ Sharks / Year just for there fins!
We throw 8.100.000.000.000 billion Tonnes of rubbish into the Ocean every year!
There is already 6 times more plastic in the water than Plankton!
We have 21% Oxygen in our air only 4% is made by Trees the other 17% is made by Corals! Our Body needs 4% of Oxygen every breath.
so now tell me how “intelligent” we humans are?!
Finally our new Boat has arrived!
She is called Poseidon 1. On the way to Krabi to get it ready in hopefully 10 days! Like it? We do very much!
There will be a Lounge with Music a Bar as well as Hot Water Showers & Toilets. More comfort is almost not possible! 😉

Scuba Diving Law of Boyle & Mariotte in a practical Example! A bubble-ring is expanding towards the surface.
Hey there green thumbs!
A couple of days ago we did our October Underwater Clean up day! Successfully we get less and less ropes and nets!
We went out for Scuba-Diving on the 12.09.2012 to our local Island Reefs to do some clean up, small rubbish bags and plastic. But we were overwhelmed when we saw a big net about 30m in length and 15m in width stretching and hanging over the pinnacle at Koh Talu at our first dive site!
Fishing in these waters can cause problems like this because the fishermen throw the net, which will too often get entangled into corals! They will then just abandon the net and leave it on the reef! This not only leads to death for so many fishes and other marine life, such as turtles and cuttlefish, but also causes serious damage to the coral life. If not removed, more and more marine life gets entangled and dies from starvation and suffocation!
Many People don’t know that most of our Oxygen gets produced by Corals, but if they are stressed by a net they will die, fishes will move away and the whole reef becomes a “Serengeti Desert”.
Corals are the slowest growing creatures in the world! Some of them will only grow as slow as 0.01 millimeter per year, even the fastest growing corals only grows about 1 centimeter per year. But they can die in a day!
We removed the net as carefully as we could to not break more corals than had already been damaged and I was glad to have 4 other divers with me to help take care of it! I couldn’t have done it myself! Thank you very much to Jai, Roxanne, Happy and El! With all 5 People we were not able to remove the net on our first dive so I took the guys back to our boat and returned to remove the rest of it by myself!
When we did our second Dive at Koh Meaurai which was supposed to be a Fun dive we came across another huge net about 20m in length and 10m in width, lots of dead fishes entangled and struggling ones too! We carefully cut out those that were still alive, but, sadly, they were few! There was a tasseled Scorpionfish entangled in the net; Scorpionfish are very dangerous and it’s even more dangerous to cut them out of the Net but fortunately we could manage without getting stung!
We managed to get the two nets on the boat and once back on shore, we ensured proper disposal.
I wish something could be done urgently to improve and implement better fishing practices, not just in Asia but throughout the world, in order to maintain and preserve our fragile and diverse marine life system!
This morning was a wonderfull morning we released 86 turtles which were one year old from a Turtle farming station! I wish the small turtles lots of luck and hopefully we will see you underwater again!!! Take care my friends!

Amazing Footage from a “Techno Fish”!
A Harlequin Sweetlip juv. is doing this move to protect itself from predators, it looks like a big toxic ball! as the older it get as the less it needs to protect itself as the slower it can do it! Amazing creatures, so advanced!
Help us to Save our Sharks with your Signature!
With a mouthful of teeth, sharks do not seem to need much protection.
In fact one shark goes through thousands of teeth in a lifetime. Each row of succeeding teeth is larger than the set before.
But sharks´teeth are built for eating. The shape of a sharks teeth depend on the type of food it eats, and some sharks’teeth change shape as they grow older and their diet changes to suit the needs of their growing bodies.
sharks also have other types of protection. A protective lid, called the nictitating lid, helps keep its eyes safe from harm when it attacks prey or nears an unfamiliar object. Some sharks will also roll their eyes back into the sockets showing only the whites while attacking prey to protect the more important seeing part of the eye.
Bottom feeding sharks, such as the angel shark or wobbegong, have coloration matching their environment. Others will bury themselves in the sandy ocean bottom.
However, sharks have little or no protection from humans who hunt them for almost every part of their body to make leather, jewelry, soup, cosmetics, and other items. Sharks are also hunted for sport and many are inadvertently caught in fishing nets or in nets placed to protect humans.
However; the product that drives the market are the fins. After drying, collagen fibers are extracted from them, cleaned, and processed to make ‘shark fin soup’. In spite of the fact that these fibers have little flavour or nutritional value, the soup is considered a delicacy, and may sell in the Orient for more than $100 ( £65) a bowl. As long as the humans pay a lot of money for these fins, it will never stop, and we will kill the sharks and ourselves
The explosive growth of the Chinese economy and rapid expansion of trade with the outside world during the 1985 and 1995 created an unprecedented situation. Suddenly there was an insatiable demand for shark fins of almost any size or type. Improvements in shipbuilding and navigational electronics meant that shark fishing boats could now go anywhere in the world, moving from one place to another as local shark populations were destroyed. The fins are now so much more valuable than the rest of the shark that the carcass is often discarded after the fins are removed, to save storage space on the boat. Often the fins are sliced off when the shark is still alive and the mutilated shark is dumped back into the water, where sinks straight to the bottom because without back fin can´t swim, to die a slow and agonizing death.
Helping To Protect Sharks
Since sharks reproduce at a much slower rate and mature more slowly than bony fish, it is important that people are careful not to deplete the shark population to a point where it can not be recovered. In some cases the environments in which the sharks live are being destroyed.
While sharks have a bad reputation, they rarely attack people unless they are provoked or mistake a human for their normal prey. More people drown in the ocean each year than are attacked by sharks. Only a few of the 365 types of sharks, the bull, the great white, the oceanic white-tip, and the tiger shark are aggressive toward human.
Encouraging the use of electric barriers instead of nets to keep sharks out of an area is one way to help. Also discourage the hunting of sharks for sport or the production of unnecessary articles such as jewelry and souvenirs. In addition learn more about sharks and inform others of ways to live peaceably with these fascinating animals.
A Shark’s Sixth Sense
In order to live and hunt in the ocean waters, sharks have the same 5 senses as human do. They have smell, taste, touch, hearing, and sight. These senses vary in their strength. Many sharks have sharp eyesight, some of which seem particularly sensitive to movement. Most sharks also have a well developed sense of smell.
However, sharks possess a sixth sense which people do not have. Sharks are able to detect weak electrical signals generated by their prey. This sense is detected through small sensory pores called ampullae.
• The smallest shark is the dwarf dog shark which is 6 ½ inches (16 cm) in length.
• The largest shark, ranging up to 40 ft. (12m) in length is the whale shark.
• Whale sharks are large non aggressive creatures which will sometimes allow divers to hitch a ride by holding on to a pectoral fin.
• Most sharks give birth to live young rather than lay eggs.
• The shark with the longest tail is the thresher shark. Its tail can be 5-8 ft. in length, or as long as its body.
• The hammerhead shark swings its head from side to side as it swims, allowing it to use its well developed sense of smell and many ampullae to search for prey in a wide variety of directions in a small amount of time.
• The fastest shark is the Mako, which can swim at 20 mph (32 kph) and leap completely clear of the ocean surface when it is excited.
• Angel sharks have extra large pectoral fins resembling angel wings. These sharks spend their lives mostly on the ocean bed resting in the sand waiting for prey to come to them.
• Some sharks migrate hundreds of miles using what scientists believe to be a sense of the earth’s magnetic field to guide them.
• One shark makes oval shape bites in its victim, by creating a suction with its lips and swiveling around for the bite. It is appropriately named the cookie cutter shark.
• One of the smallest sharks, the lantern shark, grows to only 8 in (20 cm) in length and glows in the dark.
• The most recent discovery of a shark was not made until 1976. This was the large Megamouth shark, of which only five more have ever been found. This unusual shark which feeds on krill has luminous organs around its mouth.
