A group of eggs in a single nest.
2
Name the six species of Sea Turtle (also known as Marine Turtles) found in Australian waters.
3
Choose two of the Australian species of Sea Turtles and describe the following for each:
- What is the scientific name?
- Where does it live?
- What are its identifying features?
- How many eggs does it lay in an average clutch?
- What age does it reach maturity/start to lay eggs?
- How long do its eggs incubate?
- On average how many clutches will it lay in a season?
- How long can it hold its breath when active?
4
What are two main things that will disturb a nesting turtle?
Light and movement.
5
When might the Rangers at Mon Repos, Qld and at other Marine parks, relocate turtle eggs?
When they are laid below the high tide line, when the nest is too shallow, when temperatures are predicted to be high, or if the nest becomes exposed with dune erosion.
6
At warmer temperatures (above 28°C), do we see male or female hatchlings produced?
Female.
7
How can you tell adult male and female sea turtles apart?
Male turtles have long tails, female turtles have short tails. Male turtles will only leave the ocean to bask, female turtles lay eggs.
8
What are the top three human threats to turtle hatchlings?
Artificial light, marine debris/plastic/rubbish, beach modifications such as seawalls, tyre tracks, beach furniture and fishing nets.
9
What day did God create the animals of the sea, and where in the Bible is it found?
God created all the sea animals on the fifth day. Genesis 1:20-23
10
Successfully observe Turtles laying eggs at Mon Repos, Qld (or other Marine Parks in your area). If this is not possible, consider viewing/researching/observing videos on Turtles laying eggs.
