LIFE CYCLES & REPRODUCTION
Backyard Biodiversity Wild Action

Pythons are oviparous, which means that they reproduce by laying eggs. Some pythons actually coil around a clutch of eggs and ‘shiver’ to increase the temperature surrounding the eggs.

Some birds have amazing camouflage on their eggs, to avoid predation from other animals.

Did you know that sex determination in crocodiles in dependent on egg incubation temperature?

Giant burrowing cockroaches are sexually dimorphic, where males have a much more pronounced ‘scoop’ on their pronotum. It kind of looks like a skate board ramp!

The Carpet python is an oviparous snake, averaging 25 eggs in a clutch. The female will defend her eggs by coiling around them and shivering to regulate their temperature. She will not leave the eggs to eat during the incubation period, apart from briefly basking in the sun to raise her body temperature and then returning.

While in the amplexus position. the male fertilizers the eggs as they get laid. Frogs tend to lay eggs in single masses, whereas toads usually lay eggs in long chains.

The miraculous transformation from a tadpole to a frog is called metamorphosis.

Blue-tongued lizards are viviparous live bearing reptiles. Viviparous animals are often more common in cooler climates. Find out more in a Wild Action show!

Kookaburras employ a survival strategy known as siblicide. When food is scarce a young kookaburra chick may resort to pushing it’s siblings out of the nest to their doom! This tactic will free up more food for the hungry survivor.

Kangaroos have evolved using embryonic diapause as a reproductive adaptation for the harsh Australian environment. This allows the kangaroo mother to time the birth of her offspring in favorable environmental conditions.

Frog eggs are usually laid in an egg mass, whilst toad eggs are laid in a long string of 'pearls'.

More information about this workshop

What is our Life Cycles and Reproduction program all about?

In this one-hour interactive workshop your Students will be introduced to some fascinating life cycles of various taxa, and the diverse ways species reproduce.

Learn about the behaviour of many species which enhances their reproductive success.

How many students may participate?

An absolute maximum of thirty children may participate in this program. We pride ourselves on a quality, engaging experience. Animal welfare is paramount to us. Multiple sessions for more than 30 children can be arranged on the same day if required.

What is our curriculum focus?

 Students will learn about concepts such as:

  • Vivipary (live bearing), ovipary (egg laying).
  • Reproductive strategies and behaviours i.e. embryonic diapause, sex determination
  • metatherian, eutherian and monotreme mammals 
  • metamorphisis in growth of individual species.
  • hemimetabolous vs holometabolous 
  • asexual reproduction vs sexual reproduction
  • Amazing fun facts!

What live animals should you expect to visit your classroom?

Kangaroo joey, grey headed flying fox, , echidna, frog species, diamond python, shingle back skink, tree goanna, mountain pygmy possum, tawny frogmouth, giant burrowing cockroach, rhinoceros beetle, salt water crocodile, sea stars + more!
