Wonderful wetlands

Wetlands are important for our environment, economy and our livelihoods. They have many functions from reducing floods to producing clean water and food for humans, industry and agriculture. They provide important habitat for many animals and plants. Wetlands are the great ‘connectors’ across our landscape providing places for our enjoyment and relaxation. Regardless of whether you are doing a school or uni assignment, managing a wetland or undertaking research, you will find a wealth of information here on WetlandInfo. Read more…

WetlandInfo feature species

Golden Trevally, (Gnathanodon speciosus) juveniles.

Photo by Collette Bagnato.

Our July feature species is the Golden Trevally. Adults are silvery grey, with black spots or blotches scattered on sides, and often faint bands. Juveniles and subadults are bright yellow with narrow blackish bars on head and sides, the first through the eye.

Adults can be found in both deep lagoons and seaward reefs. They typically feed by rooting for crustaceans and burrowing invertebrates in the sand but may also feed on small fish.

Small juveniles often shelter amongst jellyfish tentacles or protect themselves from predators by "piloting" sharks, other large fishes, turtles and in this case a sea snake at Howie Reef.
