For more than 100 million years sea turtles have covered vast distances across the world's oceans, filling a vital role in the balance of marine habitats.


Sea Turtles - Did you know?

These amazing creatures have been swimming in the Earth's oceans for over a million years. Learn all about these marine reptiles and how they play an important role in the oceans ecosystems..

There are seven species of sea turtle found in our waters, from the shallow seagrass beds of the Indian Ocean, to the colourful reefs of the Coral Triangle and the sandy beaches of the Eastern Pacific. Sea turtles spend the majority of their lives in the ocean - the only time they are really ashore is to bask or nest. 

Sea turtles are a "keystone species", which means they are an important part of their environment and influence other species around them. Even at diminished population levels, sea turtles play an important role in ocean ecosystems by maintaining healthy seagrass beds and coral reefs, providing key habitat for other marine life, helping to balance marine food webs and facilitating nutrient cycling from water to land.  

- Five Fun Facts - 

  1. Jellyfish are one of their favourite foods - some turtles enjoy this tasty snack, and this also keeps the jellyfish population at bay. 
  2. They are know as the oceans 'lawnmowers' - some enjoy a more plant-based diet and eat seagrass. By keeping this short it prevents the seagrass getting long and harming other creatures. 
  3. Unlike other turtles, Sea Turtles can't retract their head and flippers into their shell - the shell is part of the turtle’s spine, which can make them more vulnerable to predators. 
  4. They have an amazing sense of direction - Sea turtles can detect the Earth's magnetic field and they use it as a compass! 
  5. They can hold their breath for 5 hours underwater - to accomplish this, they slow the heart rate way down in between heart beats in order to conserve oxygen.

Let's take a closer look at each species..

The Hawksbill Turtle is a critically endangered species, they are in immediate need of conservation. The turtles weigh between 90 and 150 pounds and have a length of about 30 to 35 inches.
