New Season..

 
So after being closed for the month of November, all our Thai and western staff are now refreshed and ready to go again!
Why do we close? you may ask. Well it just gives us time to fix and replace things, also November is usually the start of the monsoon season, which ends mid December hopefully! 
What gets fixed?
Both the dive boat and longtail are taken to a boat yard in Chumphon by our Captain, who then stays and supervises any repairs, new fittings and makes sure both vessels are repainted correctly. The Engines on both vessels are stripped and serviced. New this season is a canopy that gives some shade for those on the upper sun deck. There is also a new CESA line, so we now have 2 available to our staff and students needing to complete their CESA as part of their open water course.
The Dive centre gets a touch of paint in places where it is needed and re-organised for better efficiancy when staff and customers are around. Some outside work is done to make our customers more comfortable when at the dive center.
All our Scuba tanks that need Hydro staticly testing are sent away for this, plus every tank needs to be visually inspected each year, so they can be allowed to be used for diving in accordance with local and international laws. All dive masks and fins are replaced that need replacing. All the regulatoras are serviced to Scuba Pro standards and cleaned.
This break allows our Thai staff who work 11 months of the year, time to go visit family and friends that may reside on the mainland. Most of our Instructors and Divemasters actually work at other dive centers on Koh Tao during this time, mainly because they love what they do. Which is DIVE!!
 
We hope to see many of you, very soon during this new season.
 
Merry Christmas and a Happy New Year from all at Scuba Junction Diving Co LTD. Koh Tao.

Did You Know?....

 

72% of the earth is covered in water
- only 3.5% of this is fresh water
- and 1.7% of that is ice

Water is the most important resource in the world ( and soon will be the most expansive one )

- to create a pint of beer it takes 1.720 gallons of water
- 780 million people lack access to an improoved water source
- a jellyfish and a cucumber are each 95% water

Water is the most common substance found on earth

- up to 50% of water is lost through leakes in cities in the developing world
- 85% of the world population lives in the driest half of the planet
- water regulates the earth temperature
- 10% of homes have leakes that waste 90 gallons or more per day
- it takes 7 years for the averagee American residence to use the same amount of water that flowes over the Niagara Falls in one second ( 750.000 gallons )

Water is what we all need to survive think twice....

The Uncompressive Titan Trigger Fish!


Koh Tao, our marine life is very diverse and is where I would like to take base in the Evil Titan Trigger Fish. Known scientifically as Bastiloides Viridescens. Is a beautiful and robust reef creature just waiting to be discovered. Usually swim around alone. These solitary creatures have been known to attack divers and might be cause serious injuries. But most of the time divers return with holes in them fins. People said that are getting attracted to colorful fins, what helps to don't get personal injuries.

Why the aggressive behavior?. Are merely reacting to what they perceive as threats to their nesting grounds, definitely a lesson for divers to respect the habitat of these fish, others seem to do so for fun of it. This much is clear, Titan Triggerfish are extremely territorial by nature. The male stands guard over its nest and will charge at any divers or fish that cross into its territory (the zone is a conic full circle directly above its nest). The nest is usually in a flat sandy area amongst the corals, an area that it will defend with a passion.

Bites should be taken seriously as they are ciguatoxic. That means is a natural poison which is found on some tropical reefs. It infects fish which feed on a marine algae. While harmless to the fish, even small amounts can have a harmful effect on humans. In cases of extreme poisoning, it may cause heart attacks, paralysis or death. The teeth, designed for crunching through hard shells and coral, can inflict serious wounds on any would-be intruders.

Titan Triggerfish are often solitary, and diurnal, meaning they are day-time fish, sleeping at night.

Won't always resort to violence though, on occasion just swimming at the intruder, usually a diver or snorkeler, to provide them with an escort out of the nesting territory. However, should a colorful male Titan happen to charge in your direction. It's best to do away with bravado and retreat, using your fins as a barrier between you and the fish!

More from the amazing Mantis Shrimp..

Eagles may be famous for their vision, but the most incredible eyes of any animal belong to the mantis shrimp. Neither mantises nor shrimps, these small, pugilistic invertebrates are already renowned for their amazingly complex vision. Now, a group of scientists have found that they use a visual system that’s never been seen before in another animal, and it allows them to exchange secret messages.

As impressive as their arms are, the eyes of a mantis shrimp are even more incredible. They are mounted on mobile stalks and can move independently of each other. Mantis shrimps can see objects with three different parts of the same eye, giving them ‘trinocular vision’ so unlike humans who perceive depth best with two eyes, these animals can do it perfectly well with either one of theirs.

Their colour vision far exceeds our too. The middle section of each eye, the midband, consists of six parallel strips. The first four are loaded with eight different types of light-sensitive cells (photoreceptors), containing pigments that respond to different wavelengths of light. With these, the mantis shrimp’s visible spectrum extends into the infrared and the ultraviolet. They can even use filters to tune each individual photoreceptor according to local light conditions.
The fifth and six rows of the midband contain photoreceptors that are specialised for detecting polarised light. Normally, light behaves like a wave that vibrates in every possible direction as it moves along. In comparison, polarised light vibrates in just one direction – think of attaching a piece of string to a wall and shaking it up and down. While we are normally oblivious to it, it’s present in the glare that reflects off water and glass and we use polarising filters in sunglasses and cameras to screen it out.
Light can also travel in a the shape of a helix, moving as a spiralling beam that spins either clockwise (right-handed) or anti-clockwise (left-handed). This phenomenon is called ‘circular polarisation’. Tsyr-Huei Chiou from the University of Maryland found that the mantis shrimp’s eye contains the only known cells in the animal kingdom that can detect it. Our technology can do the same, but the mantis shrimps beat us to it by as much as 400 million years.

 

Facts about Moray Eels.



They are considered to be the largest of all eels and the most common cosmopolitan eel can be found in most saltwater marine environments, freshwater systems - even in some brackish waters. The moray eel classification is not endangered up to date despite being fished commercially in many countries.

Moray Eel Habitat

Morays tend to thrive better in shallow warm water habitats and especially near the seabed of coral reef formations or hidden in rock crevices and small caves.

Muraenidae are carnivores and the biggest eel of the species, the giant moray eels, will feed on almost all mollusks, squid, crabs, cuttlefish, octopuses, and small tropical fishes such as the damselfish families.

Moray eels typically kill their prey either by wrapping their body around the victim until it is crushed flat enough to swallow or often they will simply tear its prey into small bite-size pieces using two sets of razor sharp teeth. The back row of extra teeth help to break up the food ready for digestion.

One of the most curious of all moray eel facts is that it has two circular breathing gills located behind its head. They jabber their huge jaws constantly to circulate water from their mouth towards their gills.

Top moray eel facts
- the biggest moray eel species can grow to 5 meters long and weigh up to 14 kilos
- There are more than 200 moray eel species (Muraenidae) with an average lifespan of 20 years
- A moray eel looks similar to a snake but in fact morays are fishes
- Moray's teeth point backwards to preventing its prey escaping
- Some moray eel species produce a slippery mucus which contains toxins
- Morays are voracious predators themselves, but they are also hunted and eaten by barracudas and larger sharks
- Female morays release around 10,000 eggs after mating which initially hatch as tiny larvae drifting in plankton streams
- Despite commonly having large eyes, morays do not see well but they do have a good sense of smell helping them to find prey
