zoanthid? anemone? something else? rhizo??

hi guys so i came across a cool image on deviant art but neither i nor the artist know wat it is, my suggestion was zoa but it has alot of little feeler/tenticle things within the middle of it so its kinda weird and it seems to have an opening there? o.0

Anemone 3 by *justfrog on deviantART here's the link

 

Those are yellow polyps related to zoas and palys

 

Great looking coral, definitely not yellow polyps though.

 

yeah thats y i was so confused, they almost look like zoas and then they have to many tentacles or watever and then an opening that goes straight down in its soo weird.

 

looks like a species of corynactis

 

thats it!! nice job! k+
