Dear Mohammad hasan,

You can ask your question from our colleagues Dr. Simin Dehghani in khoozestan fisheries research center. She is very famous in this field and I believe that she could solve your problem.

Shahram

Thank you Shahram.

Can you give me her contact details?

Dear Gerami,

Do you have any other specimen? This is some what difficult to identify.

Naidu,SA

Maybe some kind of retracted Anthozoa?

Where did you find it, what type of substrate? did you stain it?, what is the scale? you need to take more pictures, and you need to describe it briefly, if it has apertures, if it reflects when light is on it? etc etc. Can help you with that

Agree with Torben, looks like a retracted anthozoa.

I agree also

I also think Torben is right

Notwithstanding the absence of dimensions, it should be a retracted anthozoan (with the tentacles inside the mouth opening on the tip of the jelly body)

it is very interesting the apparent absence of any other benthos on the substrate.

Where the photo has been done?

Gb

I also suggest it is a retracted anthozoa

Sea anemone, is a formaldehyde-fixed specimen? what color was it^? hard or soft bottom? is there any stripes on its body?

Yes, I also agree with Torben

There is very little info but it also looks to me as a retracted Anthozoa. Please provide more info and pictures of your specimen.

Likely Lucas is correct, looks like an anemone to me because:

1. singe polyp, 2. has a "foot", 3. no sand or other apparently hard structures visible. Still, it is out of focus and not open, so hard to be 100% certain.

Actiniaria ........perhaps Actinia equina

I agree with Lucus, looks like an anemone

I agree, looks like a retracted anthozoan

Retracted sea anemone

Dear Researchers

Thank for your Help

here it is Geographic coordinates of Grab : 27 08.495 E and 56 21.656 E (Persian Gulf, Hormozgan Province). Depth of 6 meter. Season Spring. date of 7/April/2014

In addition I Identified these animals in grab to: Some Spionidae, Pillargidae, Amphipode, Crab, Terebellidae, Tanaeidace, Polychaeta Larval and more

but this species is unknown yet.

I thought that it was Anthozoa but it had a very soft tissue. the little hole which you see in the picture زreated by pence when i wanted to take it out from petri dish. picture was taken by Canon Laboratory Loop with *20 Magnification.

I am agree with James Reimer because it had not any hard structure.

Dear Lucas Molina

It was Alcohol-fixed specimen. i don't know what color was it because it colored it with Rose Bengal. it was soft bottom and it had no stripes on its body.

Dear Researches

Pleas Explain what do you mean by Retracted Anthozoan or Retracted sea anemone.

when you call a species Retracted? Thank you.

A sea anemone has tentacles when is not retracted...in your picture the tentacles seem to be inside

Dear Mohammad hasan,

Her email is:[email protected] and her hand phone No. is: 9166172022

Shahram

Hard to identify it from the picture. It is actually an actinarian species, but you have to examine cnidomes in column, tentacles, even sphincter muscle to make the identification possible. You can classify it as Actinaria (sp.)

Certainly I agree with Lucas Molina and Melih Çinar. This is a sea anemone (Anthozoa: Actiniaria).

I agree, it looks like a contracted sea anemone. What size is it?

ِDear Jerry

I is magnified *20

I did not measured the size

Dear Mohammad,

Did you call Dr. Dehghan?

Dear Shahram

Sorry. I will call her immediately

I can't see it properly...may be Gromia sphaerica...
