polychaete worm (?) ID...

[Vie]

Polychaete worm(s)? Not sure if the two are the same.

Both found on large sea cucumbers in two locations in the Similan Islands, Thailand (Andaman Sea). Shallow depth.

Apologies for poor picture quality...

If someone could also ID the sea cucumber(s) that would be great!
