I think it has to do with a medusa, but I dont know the species, but even I dont know if these are independent animals or parts of an animal. I found them yesterday.
4 pictures
i think that it is a medusa that has been minced on your net. What type of medusa I do not know.
The second photo shows very nicely the packed cnidocysts.
The third and fourth photos show an isolated, rather contracted, tentacle. These two photos (especially #3) also show what I think is a statocyst with a large round statolith on the left (in life at the base of the tentacle).
i suspect that a "jelly" expert would be able to identify it more closely from the nature of the cnidocysts and the statocyst.
next time you should be less cruel to the poor medusa !!
