The last two scream cucumber to me. Cukes often have "frilly" feeding ends like that.

That looks scary as hell whatever it is.

It is a filter feeding cuke no harm at all. Most do not survive long and might starve to death. The crab looks like on that I found eating some of my LPS so I would get rid of him.

Ill leave the cuke in the tank he really likes my powerheads and the crab was rehomed in my refugium. All safe and no casualties excepts some of my rock that i destroyed to get the crab out lol

I know some cukes release toxins when they die. Most of these being the very brightly colored ones, but no less its possible.

the sea-apples are the ones your thinking of most do not have this problem the filter feeders as far as I know do not release toxins into the tank.
