MERHABA DOSTLARIM,
As you may well guess, my present posting concerns the "other aspect" of the Knobbed Helmet Shell -Cassidaria echinophora-, which was the subject of my last posting. A predatory snail of shallow to deeper sandy bottoms which feeds on some echinoderms.
A member of the Cassidae (formerly Cassididae) family, it is an inhabitant of suitable biotopes in Mediterranean - Aegean seas.
From this "apertural aspect" the not so steep, moderate spire with a pointed apex is easily visible. The large body whorl ends in a large aperture shaped roughly as a half circle, the outer lip of which forms a flared and thickened varix with more or less perceptible rounded teeth towards the interior of the porcellaineaus aperture. The inner apertural lip flares and spreads towards the "columella", the visible axis of the shell, forming a broad, shield like structure over it. The glossy-white aperture draws into a siphonal canal anteriorly, and when the live mollusc is somehow threatened by other predators, it draws inside the shell, while a horny, semicircular operculum on the posterior half of the median muscular foot closes the aperture opening tightly.
This aspect of the shell was photographed under nearly straight down natural daylight slightly off-center towards right, with open-shade characteristics to demonstrate the apertural area at its best. The shell was placed over (not on!) a black BG.

hocam, bu güzel kavkıyı tekrar görmek pek güzel, hele böylesine güzel çekimle. siyah fonda harika bir görünmüm.
bu tür kavkıların parlak mineli kısımlarını çok severim. burda da çok güzel görünüyor. elinize sağlık, iyi geceler.

Hello Mehmet!
Maybe it is another picture of species which wa presented by you before, but I like it :) Very good sharpness and clarity. I like also point of view for this shell :) Black BG adds a lot to this presentation :)
TFS and have a nice evening!

Hi Mehmet, fantastic shell with splendid colors, great DOF, perfect focus, fine details and excellent sharpness, very well done my friend, ciao Silvio

merhaba Mehmet hocam,

Siyah fon üzerine belirgin bir şekilde nefis yerleştirilmiş bir deniz kabuğu,. Ayrıca kabuğun içindeki parlak, kaygan sedefimsi yapı çok etkileyici olmuş. iyice bakıldığında, üzerine dokunduğunuzda nasıl bir etki oluşağını hissedebiliyorsunuz. Elinize sağlık saygılar.

This side too is equally beautiful, Mehmet.
The arrangement of the shell is very impressive. Gives a veritable three-dimensional appearance in this presentation too.
Thanks and take care.

Merhaba Mehmet,
I was hoping that you would show us the ventral aspect of the Knobbed Helmeted Shell. The fine technical quality shows the shape with the substantial lip of this interesting species.
Thank you and my best wishes with Greetings for the festive Season,
Ivan

very nice and unusual lips, TFS Ori

Merhaba Mehmet Hocam,
Bir önceki kabuklunun ventral açıdan çekilmiş bir karesi olsa gerek. Kullandığınız kusursuz teknikle müthiş bir derinlik ve üç boyut hissi vermişsiniz. Emeğinize sağlık.

Hallo Mehmet
Your images are always like a big present to be opened, because each one of them are unique and a surprise on its own. Like always your presentation is great and precise like I have become to know you. Once again you present another gem to be place in the treasure kist with all the other beauties before this one. Your portfolio is rich with riches from the sea. This lovely Knobbed Helmet Shell being one of them. I know it cannot be, but looking at this image reminds me of the caramel and peanut dipped ice-cream cones we used to eat as youngsters. Details are very fascinating.
Best regards
Anna

Merhaba Mehmet,
un'altra meravigliosa immagine di questa conchiglia in una splendida composizione dal marcato effetto TD e dalla straordinaria definizione, magnifici i colori e come sempre ottima esposizione con BG scuro.
TFS.
Maurizio

Mehmet hocam detaylar çok güzel.. Altındaki bilgiler ise gerçekten muhteşem.
Ellerinize emeğinize sağlık

Hello Mehmet,
Great follow-up post with this alternate POV.
As with most of your shell images, the black BG serves very well.
Nice details & natural color with an informative note.
Happy Holidays,
Howard

Hi Mehmet.
Unfortunately I have not 50 mm Nikon lens yet :)))
However, I have missed your second presentation of the nice shall. I do not size of your specimen but I remember there were many similar shells in our region in my childhood. Reproduction of the shell is brilliant and one of the best I suppose. I can feel the texture of the shell and its cold hardness. My compliments and TFS. Perfect job as usual.
Alexei.

Merhab Mehmet Bey,
Bu deniz kabuğu benim en sevdiklerim arasında yer alır. Bende birde buna benzer olupta içi kırmızı olanı var ama bugüne kadar tek bir tane bulabildim ki 9 senedir deniz kabuğu kolleksiyonu yapıyorum :) Paylaşım için teşekkürler.
Saygılar,
Gamze:)

What an amazing shot!The details and, as usual, the learning for me, are great!
Thanks so much, my friend Mehmet!
Goldy
