Key morphological traits:
Fun fact: Coarsehand lady crabs mostly eats molluscs, especially Spisula solidissima (Atlantic surf clam).
Barnacles on dying seasnake. I haven't yet found any images, but it does fit the description in Lanchester, W.F. 1902. On the Crustacea collected during the “Skeat Expedition” to the Malay Peninsula. Proceedings of the Zoological Society of London, 1902 (2) 363–381, (371). See also https://inaturalist.ala.org.au/observations/95904678
The tide was rising very rapidly this day. The barnacles host was a very small wavy turban. There were many of the wavy turbans in all sizes scattered throughout the rocky tidepool areas and shoreline. There were also different species of barnacles on many of them. And yes, I know a tripod would have helped the shakiness.
In the posting link below, on a much larger Wavy Turban Snail Megastraea undosa, there were Triangle Barnacles. However the size made little difference to what specie(s) used them for their hosts.
Triangle Barnacles B. trigonus
First appearance ... about 2 months earlier than usual!
I think the initial ID is correct based on the explanation by @thebeachcomer here - https://inaturalist.ala.org.au/observations/60777300
Dominant upper intertidal barnacle on the south-facing riprap here (see last three images). With their narrow apertures and pronounced ridging, I don't recognize these small barnacles at all.
A lone small Goose Barnacle (NOT Mussell spat as I first thought) attached to a Cuttlefish shell.
Notable because they don't appear en masse until late July into August.
Collected from offshore reference system mooring. Attached to biofilm on settlement plates. Stored in ethanol.
The barnacles had been rafting on Sepia apama cuttlebone, and were washed up on beach. Barnacle colony was refloated after being photographed.
less than 1mm in diameter on the back of a seapill isopod
found this big crab cephalothorax today - i have never seen this species before. it looks like a swimming crab to me. there is a lot of hairy setae all over it. at first i thought it was perhaps achelous spinimanus, but after looking at other observations on inat i think it may be achelous tumidulus
Similar to a species I have found near Sanibel, Florida. I guess the genus is the same.
I am pretty sure this is a de-shelled Crepidula fornicata. It was just out on the mud, that is, it wasn't out of its shell because of anything I did to it (and the shell was nowhere nearby).
I found more interesting stuff under this one rock than I usually do all day. To start with, this is the first of these I've come across.
The 'veil' was lifted when I first turned the rock, but it quickly dropped down.
Then, check out all the stuff that's living on it's back.

Collected from Bondi offshore mooring as part of thesis on Lepas
Attached to jellyfish. See obs: https://www.inaturalist.org/observations/97524278
Found attached to a large stranded jelly. As I approached it retracted leg-like appendages.
Has tiny claws, found face down, saw shell moving and it was difficult to pick up
found embedded in beachcast sponge

I think the first image (a gif) only works on desktop!
This was a real mystery until I broke it open ... the creature inside certainly looks like a Barnacle to me.
Quite small, diametre of maybe 1cm, several of them, near lots of dried up blue bottles and same colour as tentacles, but didn't seem to be tentacles. It didn't sting. Was soft. Wondered if it was some type of slug with spherical cerata?? or a tunicate? I have no idea.
Interested to know what the barnacle-esque structures on the leaves of this Grey Mangrove could be.
