Dear Gul,

It can be Acanthocardia cf. tuberculata it is very difficult to identify from such a small image.

Best wishes,

Hi, in my opinion it could be a species of the genus Parvicardium, maybe P. exiguum.

Cheers Michael

Dear Dr. Levent and Dr. Michael,

I have checked both of these species, it is something else! rounded on one while, sloping on the other side. Some shells are further straightly sloping. The largest shell is 1.5 cm.

Here, I have attached the same images but larger then before. See attached word file.

Thanks

Dear Dr. Gul,

You can check your specimen with the Shell of Oman . I think you may find some related species.

Best regards,

It is Timoclea imbricata   (Sowerby, 1853)

Yes it is Timoclea imbircata

I have been studying this species for last 40 years. It is Timoclea imbircata which is found subtidally upto a depth of about 40 m.

Great information Muhammad MOAZZAM Khan ...for my knowledge, this species reported from Indian Ocean. I don't find any such information of this species from Pakistani waters except reported Nazneen, S., & Begum, F. (1994). This is uncommon species still description, habitat and biology are not in detail. Can you please share the article or any reports?. It would help. Thanks.

Saedul Bibi they are found in large no as a dead shells no live specimen was found and there is no such publications regarding Biology. You should go through original description.

Faiza Iqbal can you please share location of the species ? thanks
