Not much too it unfortunately. I had some captain america palys on my frag rack. You can google them; they are pretty distinctive; all my results looked just like what I had.I have to hear the story about the palytoxins!
They'd grown onto the rack so when I pulled the plug up they tore, unknown to me. I then placed them on a rock.
Sometime shortly afterward I scratched my eye.
Instant and incredible pain. I tried to flush my eye in the shower, didn't work. Went to the ER and got some drugs. By then damage was done; had a massive cornea ulcer. Day later when the specialist looked at it he said he'd "never seen anything like it. It's like your sclera melted."
Tossed those palys in the garbage.
These days I would recognize those specific palys as being 'enough like cf toxica' to avoid entirely. If I had to guess I think they are some morph of heliodiscus but obviously still toxic enough.
Made a full recovery. Got lucky, all the scar tissue is off to the side, so it didn't affect my vision.
But between it and the long spine urchin I can't tell you which hurt worse. That thing is banished to the QT pest tank and at this point it's so big I have no idea how to actually move it.
