Sea turtles of Queensland, Australia

Wildlife

Residents of Queensland are fortunate to have such a rich sea life right at their doorsteps. In fact, six of the seven marine turtle species of the world make their homes in Queensland. While the leatherback only visits during the winter, the remaining five stay their entire lives here. Since there is so much to learn about the differences between these beautiful creatures, we’ll cover three of the most prominent.

Green turtles

Also known as Chelonia mydas, the beloved Green Turtle has a very rounded head, helping it glide through the waters. It’s a fairly sizeable turtle, growing up to four feet long, on average, weighing over 400 pounds. It’s easily identifiable by the large scales, four on each side of the shell. Although, they are called green turtles, the shell can have reds, browns, and blacks. Green turtles like the coral reefs for protection and to feed on the algae and small prey.

A female green turtle can lay up to 115 eggs. They come to nest between the months of November and March, typically on the islands that sit north and south of the Great Barrier Reef. Raine Island is the most popular viewing location.

Hawksbill turtles

Also known as Eretmochelys imbricate, the Hawksbill Turtle is the smallest turtle of the bunch, growing to about three feet in length, on average and weighing around 150 pounds. Their head is very narrow and they have a beak-like mouth, hence the name. Hawksbill turtles are the only sea turtles with two pairs of prefrontal scales on the head and four pairs of costal scutes on the carapace. They have very distinct scale patterns and are easy to identify this way.

Like the green turtle, this turtle species also prefers algae, seaweed, jellyfish, etc. They will lay slightly more than the green turtle, averaging around 130 eggs. They stay around the northern Great Barrier Reef and the Torres Strait, nesting all year, but with the most occurring in the months of Jan. and Feb.

Loggerhead turtles

Also known as Caretta caretta, the Loggerhead Turtle grows to a similar size as green turtles, but with stark contrast in shape and color. Their heads are more pointed and their jaws are more prominent. Their shell has a heart-shaped pattern, with five scales on each size. Loggerheads are red and brown in color. They are less camouflaged than green turtles, for example, as they prowl shallow waters around the Great Barrier Reef for crustaceans, sea urchins, muscles, and the occasional jellyfish.

Loggerheads will lay about 125 eggs from November until the end of January on the Bundaberg Coast in Queensland or on the islands to the south.

How dolphins communicate (and why you should leave your jet ski home!)

How dolphins communicate (and why you should leave your jet ski home!)

Wildlife

Unlike other sea creatures, Dolphins have their own societal structure, and they do communicate with one another. It’s unlike anything you see in the animal world, and you have to ask yourself how does a dolphin maintain a social network? How do dolphins communicate with one another? During the Dolphin kayak tour, you will be able to find out all of that and so much more!

Echolocation

The way dolphins communicate is via echolocation. This is a biological sonar that marine mammals such as dolphin use to stay in touch with one another. How does it work? Dolphins create both low or high pitched sounds, based on what they want to share with their brethren. They also measure the amount of time it takes for sounds to bounce off objects until they reach their designated target.

Aside from communicating with others, dolphins also use echolocation to figure out where objects are located, what direction they are traveling towards and so on. Since the dolphin vision is rather limited, they have to rely on sounds, and this helps them quite a lot.

Body language

However, echolocation is not the only method of communication used by dolphins. They also depend on the usage of various body language signs to communicate with one another. Body language comes with different signals. Usually, this integrates things like tail slipping, jumping, bumping into each other, spy hopping and many others.

The issue is that man-made sounds can affect Dolphins. If people create lots of powerful sounds and spread them within any ocean, dolphins are the first ones to suffer. Since they rely mostly on sounds and they have an acute sense of hearing, they will be damaged immediately, and they will not have the ability to communicate because of it. This is why the use of sonars is prohibited in regions that are full of dolphins. This is also one of the main reasons why jet skis around Double Island Point scare the dolphins away! Please leave your jet skis at home.

How can you interact with dolphins?

The fact that dolphins communicate with one another is cute, and it just shows the unique appeal that these outstanding creatures bring to the world. If you want to view our local dolphins, then join us on tour! We are offering some incredible Rainbow Beach tours and Noosa tours exploring the headlands of Double Island Point and its wildlife!

Why should you embark on such a tour? Not only do you get to explore the ocean and have fun with the group, but at the same time, you can enjoy the company of cute dolphins that swim all around you. It’s an incredible opportunity, plus you get to visit some of the most popular locations in the region.
