Have you heard of Gladstone’s Big6? Do you know where you can find them? 

If you answered NO to these questions the Gladstone News team have a challenge for you!  


Shorebirds are the birds you’ll find feeding along the coastline. Many species are migratory, so will only call Gladstone home for a short time as they fly from place to place with the seasons. Many of these birds enjoy Gladstone’s range of habitats, and usually love to get a feed from mudflats, like this terek sandpiper eating a delicious worm! 


Turtles are very cool aquatic reptiles and Gladstone is very important to the lives of two species in particular – the flatback and green turtles – although you can find others like the loggerhead, the leatherback, the olive ridley or the hawksbill foraging in the region too!  


Whales and dolphins are cetaceans, the scientific order (or group) of marine mammals that share plenty in common with humans! Despite living in the ocean, like all mammals, cetaceans: 

  • have hair
  • breathe air
  • drink milk when they’re young.  

They are playful and intelligent animals that use sound in different ways to talk to one another, find their way, or catch food. Humpback whales even sing beautiful songs as they travel up and down the coast. There are two types of dolphins that call the waters off Gladstone home – the Australian snubfin and the Australian humpback. The map below shows you where you’re most likely to find them in the Gladstone region. 


Gladstone’s waters are full of fascinating fish that have amazing survival and predatory traits. Did you know that a barramundi will change from being a boy to being a girl at about five years of age? The barramundi don’t know this, but their sex change is a smart move – the Queensland Government has laws in place to protect large female barramundi from ending up on your dinner table.


Gladstone is lucky to be home to dugongs, the mysterious mammals that may look like overweight dolphins but are more closely related to elephants.


What has two pair of antennae and no backbone? A crustacean of course! This family of invertebrates includes well-known hard-shelled critters like crabs, lobsters and prawns. Mud crabs are one of the coolest crustaceans. They are mostly found in Gladstone’s intertidal areas where they live in burrows in the mud, emerging at night to look for food using their 360 degree vision! They are also very dangerous (to fingers and toes) if they get hold of you as their powerful claws will stay jammed shut even if separated from their bodies – check out the size of them in the picture below!


Have you been lucky enough to see these iconic creatures in their natural habitat?
