I went for a walk along Eastern Beach with my mum and nephew recently. We hadn’t had a good low tide during the day in months. I was super keen to see what interesting marine life we could find or if anything had washed up.
Alas, we may have gotten distracted by a cute dog. I still managed to find some cool sea squirts.
Our first thought when we found the above sea star was that is was the pest species Asterias amurensis. My gut said that it may have been something else. The ends weren’t tipped and curly, and it didn’t feel purple enough.
It turned out that it was a native species called Uniophora granifera. It was kinda scary, it shows how easy it can be to misidentify a species. This is especially important when it is an invasive species and relies on the community to help remove it.
I was lucky enough to find a number of sea squirts washed up. I suck at identifying species that have washed up; I’m only *just* learning the basics about the ones I find in the water. A lot of the identifications are guesses.
Think this may be P. Dalbyii, but this is based completely on the siphon colour. It is too fresh to see the colours of past ones I’ve found.
I can’t find any ones in the guides that fit the colouring here. I’m getting a deep red/purple vibe. Maybe Microcosmus, but that is pure guess.
I don’t know is this one type of sea squirt, multiple types of multiple types of species.
This is more orange-ish. Maybe Pyura? I definitely need to learn more about sea squirts!
These are what I believe is Pyura Dalbyi. All of the other times I’ve seen it is while it is in the water, or has been dislodged and washed up. It’s fascinating seeing them in situ; I don’t think I’ve seen them with that red stuff on them.
They were on a wooden support underneath the main promenade. I was maybe a meter in the water and it was only 30cm deep. Unfortunately, I was in a tight and dress so couldn’t explore as much as I wanted. I was also with a 15 year old who was super keen to go beyond the promenade and check out the rocky area.
