What are these?

[Kimberely]

Noticed these on my cabbage leathers. No clue what they are. Can someone ID?

Top pick looks like the shape of a nudibranch.

They're hard and actually sticking out of the leathers. After some more research, I believe they're spicules.

oh ok. Yeah I cant tell from the pic. That's definitely not a nudibranch as they are soft and mobile.

They don't look irritated or anything so I'm not gonna worry too much.

Those are sclerites and indicative of leathers.

Thanks. Everything I was finding was referring to spicules and dying coral. Mine doesn't look that bad so I wasn't sure. Very much appreciated!

My cabbage used to drop them all the time I always hoped they'd grow into more coral but no such luck...
