Great Barrier Reef Diving, Snorkeling & Sailing Tours with Small, Fun Groups

This is the most common shark spotted by our guests, whether they are snorkeling or scuba diving. The white tip reef shark is a relatively small shark. The average size only measuring about 1.8 metres or 6 feet long. This is one of the best parts of our jobs, seeing people who less then 30 minutes ago were scared about sharing the water with a shark. Now they are seeing them up close and experiencing sharks in their natural habit. Immediately realizing that all the television and movie myths are just that myths. One of our guests last year went from being a nervous snorkeller to scuba diving, and her reason I want to ‘dive with the sharks’.

As you can see from the photo above, all sharks do not require to keep swimming to stay alive, this again is another myth. White Tip Sharks can move water through their gills as they lay still on the bottom. This species of shark tends to hang around reefs for long periods of time, sometimes years. They hunt at night feeding on octopus, fish and other reef creatures, including lobsters and crabs. Not a bad diet. During a night dive, you can observe them slowly swimming along the reef edge looking for that evening snack. Unlike other shark species they do not get into a feeding frenzy.
They are not aggressive towards humans at all, unless provoked and then purely a defensive measure. Humans feeding sharks can lead to confusion and sharks may mistakenly grab the hand that feeds it. Another good reason not to feed the fish, especially the big ones with big teeth.

White Tip Sharks pregnancy lasts about 10-12 months. They give birth to young called pups, this litter can contain anything up to 6 pups. Now how did the white tip shark get its name? Very easy, the white tips on the tops of the fins.
Current populations of white tip sharks are depleting at the rate of about 8% per year, due to unsustainable fishing practices in other parts of the world and its slow reproductive rate.

Swimming and diving with sharks that you must experience to really appreciate. The only way to dispel the myths and see the grace and beauty of a shark it to come and experience it in the sharks natural habitat.

Very popular with scuba divers on our trips to the outer Great Barrier Reef, barracuda are an impressive sight on the reef. The fearsome looking barracuda has a reputation for being and aggressive fish but it is mostly undeserved. They really use their incredible speed to shock and attack its victims of smaller fish. They do not see humans as a meal or as a threat unless actively provoked. They have been known to get aggressive where potential food is involved, another good reason not to feed the fish or support operators that feed fish.

They are often seen in large groups in the early morning or late afternoon hanging around at the back of the reefs. What are groups of barracuda called? Batteries. The can grow to about 1.6 metres or just over 5ft, the guys in the photo above are just over a metre each. They have a large swim bladder (gas filled bladder) they use to control their buoyancy in the water. This allows them to hover perfectly for long periods of time with very little use of energy.

The Moorish Idol is a common fish around the reefs and prefer to swim around the top of the corals feeding on sponges, and small invertebrates. Our snorkellers and divers often encounter the idol as it grazes amongst the coral gardens of the Great Barrier Reef.

It is easily recognized as it has a thin body with a round shape. This is highlighted but very distinctive yellow and black bands with white contrasts that run vertically up the body. During the night these colours actually become more dull and sink to the base of the reef for protection from predators. They also have several long dorsal spines that extend from the main part of the fin to flow over the back of the idol.

These fish are very popular with aquarium owners because of their bright colours and trailing dorsal fin. However they are notoriously difficult to keep alive, they can be very picky eaters and require large tanks as well as good water quality.

Moorish Idols mate for life. The release their eggs to drift where they drift until their larvae reaches about 7cm or 3in, when they as juveniles start to swim on their own and develop into mature adults.

These rays are a great thrill when you get one that is remaining still enough for you to get a good look it. Our divers always remark and remember the encounter as one to remember for years to come.
There is no wondering how this fish got its name, its big wide flat head and the way it works its way across the sand clearly resemble a shovel. They are also known as the guitarfish. Looking like a cross between shark, ray and fish the shovelnose ray is something completely different.

The shovelnose ray eats small crustaceans and are therefore seen around the base of reefs and grassy sea beds. When not feeding they like other rays they tend to bury themselves in the sand. So when diving keeping a close eye out and paying close attention to your surroundings you may catch one of these guys chilling out in the sand. But stay away as they are timid creatures and will probably take off as soon as you approach, so just check them out from a distance.

The shovelnose ray gives birth to live young and often twins, yes two at a time. The young normally stay around the area of their birth until they mature and start to wander off and explore areas of their own. They can grow up to about 1.8m or 6ft and have about 65-70 rows of teeth.
