Sea Turtles are marine reptiles that must come to the surface to breathe.  The males live all life in the water.  While the females come up to the beach to lay their eggs.

All six Australian sea turtles are protected under the National Parks and Wildlife Conservation Act 1975.

On Fitzroy Island in Cairns is the Cairns Turtle Rehabilitation Centre.  This team of volunteers, amazing people, cares for and rehabilitates sick or injured turtles.   Please get in touch with this group if you would like to donate and help this fantastic organisation.

Physical Characteristics

Sea turtles have unique physical characteristics that allow them to survive in their marine environment.  They have streamlined shells, which helps them easily swim through the water.  Sea turtles also have powerful flippers that enable them to swim long distances and navigate ocean currents.  Additionally, sea turtles have beak like mouths used to grab and tear their food.

Behaviour and Diet

These fascinating creatures with unique behaviour and diets.  They are primarily carnivorous and feed on various food, including jellyfish, crabs, and sea cucumbers.  Some species are herbivorous and feed on seaweed and sea grass.

They are known for their nesting behaviour, laying their eggs on sandy beaches.  The female will dig a hole in the sand with her flippers and lay her eggs.  The eggs will hatch several weeks later, and the baby sea turtles will go to the ocean.

Threats and Conservation

There are numerous threats in the wild, including habitat destruction, pollution, and accidental capture in fishing nets.  These threats have led to a declining population, making them endangered.  However, conservation efforts are underway to protect these incredible creatures.

Conservation efforts include:

  1. Protected areas: Marine-covered areas have been established to safeguard their habitats.  These areas restrict human activities that could harm the turtles and their environments, such as fishing and development.
  2. Nesting beach conservation: Conservation efforts include beach cleanups, erosion control, and monitoring to ensure the safety and health of nesting beaches.
  3. Turtle-friendly fishing gear: To reduce accidental capture in fishing nets, turtle-friendly fishing gear is being developed and promoted to fishermen worldwide.
  4. Public education and awareness: Educating the public about protecting sea turtles and their habitats is essential in promoting conservation efforts.  This education includes raising awareness about these turtles’ threats and providing information on reducing human impacts on their habitats.

By implementing these conservation efforts, we can protect sea turtles and ensure their survival for future generations.
