Diego,
This is a wonderful demonstration that all identifications should be
treated as hypotheses - constrained by the availability of evidence, and
by individual experiences.
I based my decision (Octocorallia) on 8 tentacles, well-developed pharynx
(indicating a polyp), and the aboral thickening that may be relatively
"muscular" (also suggesting a polyp). There is a small pointed structure
between the tentacles that I'm interpreting as part of it's oral structure
- if it should really be a new tentacle beginning to develop, then I'd
have to think again about whether it's realy an octocoral.
Regards
Don
