Great Barrier Reef Snorkeling Tours - 5 Things You Didn't Know About Sea Turtles

Every year from November to January, thousands of female sea turtles transform their bodies from graceful paddlers into behemoth beasts to lay their eggs on the sandy shores of Queensland’s beaches. One out of a thousand survives the ride and returns 30 years later to their nesting ground to close the life circle.

Things You Didn’t Know About Sea Turtles:

Here come the astonishing facts about sea turtles which you have not known before.

Swimming Underwater for More Than Two Hundred Million Years:

Known as ancient mariners by seafarers, tortoises have been swimming the underwater world for over 200 million years and have evolved before mammals, birds, snakes, and even lizards.


The top side of the shell of a sea turtle is called the carapace and the plastron on the underside. The carapace consists of 60 different bones and plates which give it amazing strength and protection.

Sea Turtles Feeding:

Sea turtles feed mainly on sea grass and jellyfish, but they still mistake plastic bags for jellyfish even equipped with all these sensory wonders. Don’t throw your waste into the ocean.

Sea Turtles Can Sleep Underwater for an Extended Period of Time:

Some turtles have a tendency to absorb oxygen around their necks and flippers through the skin, allowing them to sleep underwater and stay there for long periods of time up to five hours. Their heart rate drops every nine minutes as low as one beat.

Pink Zone:

Raine Island north of the Reef is a specially demarcated ‘ pink zone ‘ by the Great Barrier Reef Marine Park Authority because of the sheer number of sea turtles that come here in the nesting season. For over two months, over 3,000 green sea turtles come here every night with the sand becoming a mass of sunrise tracks.
