Zooids are multicoloured and have two holes.

Labelled as B. Diegensis
Also observed this colour at Eastern Beach and Williamstown.

Shape looks like Botrylloides Violaceus. Have never seen one that looks like this before. Could possible be due to size.
Orange seems to be darker than others I have seen.
Found at St Helens Boat Ramp
St Helens Boat Ramp. Feels more smooth and flatter than the others I’ve seen.
St Helens Boat Ramp. It almost seem like there is a large drop in the side.
Apollo Bay Harbour. Shape is different
Apollo Bay 2018
Looks a lot like B. Violaceus – am not 100% certain.
Found in Apollo Bay Harbour. Zooids seem to be arranged in circular rings. This is similar to a red/white B. Diegensis I shared above.
You can see a close up here.
St Helens Boat Ramp. It looks to be in a line, plus the zooid openings are longer.
Someone on iNaturalist said Botrylloides Niger?

Botryllus Schlosseri
Purple/white variant. In some cases, the white part was transparent. Found under rocks at Apollo Bay Harbour
Not sure if this is the same as above specimen.
Apollo Bay, near a lot of B. Schloressi. The yellowish tinge stands out; normally I see a white/purple combination in this spot. The shape is also different.
Found the purple/white coloured one at Gems Pier in Williams town.
Apollo Bay Harbour. Likely B. Schloressi but the zooids look a little bit longer, plus it seems like they are growing on top of each other
Apollo Bay harbour. Found growing on a chiton once.
Apollo Bay Harbour next to Botryllus Schlosseri. My guess is that is Botryllus Schlosseri at a different life stage.

Found multiple times at Apollo Bay Harbour. Has been collected by Marine Research Group.
Crop of specimen at Apollo Bay Harbour.
St Helens Boat Ramp. The transparency has thrown me.
Apollo Bay Harbour, 2022.
It could be due to poor lighting, but the zooids seem to have a white line in some of them.
Apollo Bay Harbour. Photo quality sucks, so can’t see any key features. Doesn’t seem to easily fit the pattern of above species.
(Paraphrased from Matt Tank on iNaturalist) Some of the systems have elongated rings, which suggests the colony is developing a more linear arrangement. This could mean Botrylloides. It could also be two systems smooshed together
