Sea Cucumber?

Had this guy coming in with the rock, purple and spikey, thought is was a cucumber, after seeing those feeler things coming out of the mouth i don't know.
That's the best pics i could get.

Definitely a sea cucumber! Those are the mouth parts they use for feeding, some species get some pretty insane tentacles going

Nice score. they seek detritus and uneaten food throughout the day
