Some venum protéines are denaturate dy heat, that is way it is told to drop the bitten body part in hot water.
Spine venum is not denaturated by heat.
I have not read this in my literature. Is it Acanthaster venom specifically that is heat resistant, or is this relevant to other echinoderm venoms? Can you point me to the reference(s) you got this from, I'd really like to update my notes.
 
Sorry it took me a while to get back on this, have been away but will now get better.
Or rather, my finger hurt so much from the COT that I couldn't type for 6 months, haha!

The COT fell on my finger because we were Cots hunting (as we do) and whilst I looked away and a Cot was perched on my bamboo stick, it fell off.

And what happaned then...? Well, eventually I got it x-rayed and there seemed to be a piece of a spind embedded in my finger, so whoever thought of that was right! :D

It took 3 months before the piece of spine finally came out (the doc said there was no point in surgery since it was small and transparent ad difficult to see, he'd end up cutting up my finger finding nothing), and there were actually two of them. Once they were out, it took another couple of weeks to heal and it's still slightly sore sometimes if I get cold.

There you go... lesson learned?
 
Archman I’m interpreting it that some of the spines we may encounter are treated with hot water, some not. I have All Stings Considered First Aid and Medical Treatment of Hawai’i’s Marine Injuries and looked for what you ask. Last time I looked them up was for Wildcard LOL. Anyway I don’t see a clear answer along the lines sky50960 mentions.
I used hot water for my first Wana puncture with excellent improvement (from severe discomfort) after several hours continued for three days several times a day and was able to remove the bulk of the imbedded spines. The second time the punctures apparently weren’t as much of a problem as I forgot to when I got home. All Stings Considered says the same thing for wana and Crown of Thorns re: treatment. Heat for treatment for pain is unproven. Some Doctors recommend, some believe it is of no benefit and should not be done.
It does say “The skin covering of the top of the sea star, including the spines, secretes mucus that contains a venom with multiple toxins.” Wana have pincers that deliver paralyzing toxin on their “body surface…. Hawai’i’s species are incapable of penetrating human skin.” And further states “People have traditionally believed that wana carry venom on, or in, their spines. Some researchers, however, think the spines are no more toxic than any other foreign protein traumatically introduced into human tissue.” It also puts all urchins into one spot and doesn’t speak of specific kinds re venom or not. It does say both are self limiting.
Seems odd to me we don’t know about wana spine toxin delivery considering how easy it is to pick them up for study. Well, All Stings was published almost 10 years ago. Hopefully sky50960 will clarify.
 
Ya but I only whined for a few days.
I have heard many versions of COT injuries, this being to the most severe, mine, just a handfull of puncture wounds that were gone in a couple of days being the lucky way out of it.......Man, make fun of someone wearing a snorkle once........:)
