I have observed various marine life forms throughout my childhood, although documented them very late. Here are a few of them which I have commonly seen.

I have observed some really interesting marine life forms around Wollongong intertidal zones and rockpool for the year 2019.
Some really interesting sea slugs such as bloodlea sapsucker, various sea hares and their egg saces, sea stars, anemones and so much.

I have documented various marine life forms around which can be observed in the intertidal zone. Best time to view them during is during low tide.
