In Port Phillip Bay during October, one of our small octopus (Octopus pallidus) lay their eggs in small caves ,bottle or old tyres.
The female stays with her eggs until they all hatch.
Over about 3 weeks I checked the progress of one female and her eggs.

Escaping from an aquarium is child's play when you are as smart as an octopus
In 2007 I was snorkelling in Dahab, Egypt, when I came face-to-face with a common octopus.
It was an intense experience.
I felt it was sizing me up, and there was an ill-defined but somehow profound communication.
Our meeting only lasted a few seconds, but I was left with an enduring impression of having encountered a great intelligence.
The experience may help explain the loud cheer I let out in April 2016, when I heard the news of Inky the octopus's great escape from the National Aquarium of New Zealand.
The lid of Inky's tank was left ajar at night, and he took advantage of this by climbing out, walking across a room to a drain opening, and squeezing down a 160ft (50m) pipe to the open ocean.
His successful bid for freedom was one more piece of evidence that octopuses are some of the most intelligent creatures on Earth.
Here are eight of our favourite octopus behaviours that illustrate just how smart these cephalopods really are.

Jennifer Mather is a comparative psychologist at the University of Lethbridge in Canada.
She has been studying octopuses since 1972.
One encounter, during field work in Bermuda in 1984, suggested to her that they were more intelligent than they were being given credit for.
Mather had watched a common octopus catch some crabs and take them back to its shelter to eat. Then it suddenly darted towards a rock about 7ft (2m) away, put it under its tentacles and took it back to its den.
The octopus did this three more times, creating a wall in front of its home. As if confident in the extra security measure, it then fell asleep behind the barrier.
Mather argues that this and other examples are evidence that octopuses are capable of foresight and sequencing of actions.
"This demonstrated to me that here was an animal with a mental image of what it wanted and one that was capable of planning," says Mather.
"It was very far removed from the automatic stimulus-response that we were used to thinking about with animals."
