Spionid on my turbo snail?

[Fungusamongus]

Hello all. Any help would be great. This is a turbo snail i got and i just noticed these waving about on its shell. They appear to have 2-4 sweeping arms. Top of the first 2 photos. Left side next few. Thank you in advance.

I found a post on R2R with another snail that had these sane things. Spionid was the answer there. Well, turbo shells are completely clean now. Thanks to all that contribute to the forum.
