Why unlike any other???
Well, I browsed the entire TN category "Molluscs" and I did not find even one shot showing the internal structure of a gastropod shell. So here it is...

But there is also another reason for posting this shot. I bought a new camera - decided to enter digital SLR world. I used to photograph with Canon in good old analog times, so this time, impressed by the quality of shots (also from TN) and its versatility I've bought EOS 350D (in USA Digital Rebel XT) three days ago. With the terrible autumn weather we have here I'm still testing it mostly at home and that's one of my first images with that camera - I couldn't wait to post something... forgive :-)

So what is a SHELL???. It is the hard, rigid outer covering, or integument, of certain animals. More specific scientific names include exoskeleton, carapace, and peltidium. A shell may be made of nacre (a combination of calcium and protein), chitin, bone and cartilage, or silica.

While many sea animals produce exoskeletons, usually only those of mollusks (also spelled "molluscs") are normally considered to be "sea shells". The majority of shell-forming mollusks belong to the classes Gastropoda (univalves, or snails) or Bivalvia.

The shell will grow over time as the animal inside adds its building material to the leading edge near the opening. This causes the shell to become longer and wider to better accommodate the growing animal inside. A mollusc shell is formed, repaired and maintained by a part of the mollusc called the mantle.

Protoconch - the apex, it's the part of the shell with which snail emerges from egg.
Spire - a part of the shell between apex and the opening. Spire consists of whorls bordered with sutures. Each whorl represents a growing stage of the snail. The last, biggest whorl is opened and it's called "body whorl".

The spiral structure you see inside along the entire shell is called columella and it's the "spinal chord" of the shell structure.

Malacology, the scientific study of mollusks as living organisms, has a branch devoted to shells, called conchology - although it should be noted that these terms are sometimes used interchangeably, even by scientists (this is more common in Europe).

Cerithium sp.
Family: Cerithidae
Order: Mesogastropoda
Class: Gastropoda

This is a family of small and medium sized temperate and tropical marine snails living usually in shallow waters, on sandy or gravel bottom.

This specimen was found by my wife among coral gravel with many fossil and fresh shells on a parking space behind a seafod restaurant on Marco Island in south-eastern Florida. It's amazing how exactly it's cut through. I guess someone did it for purpose and then lost it...

Hi Michal

This is trule a unique post! Thanks to people like you, we get to see all sorts of new and cool things. I remember studying about these in my first year of college :)...eh...good times :))
Anyway, i also want to congatulate you on your new "toy". I'm sure you're going to love it and i hope to see many more photos taken with it :)
Great photo, great notes...great work!
Cheers and TFS

Fantastyczny post!
Po pierwsze temat - faktycznie malo jest mieczakow na TN, a juz takiej podziurawionej muszli nie bylo na pewno. Po drugie - walory artystyczne zdjecia :-) Eksponat wyglada jak jakis rytualny noz z Polinezji albo ultranowoczesny sprzet kuchenny :-) Po trzecie notka - troche ciekawych faktow naukowych, ale przede wszystkim 'cos od siebie' - takie notki lubie najbardziej. I po czwarte wreszcie - bardzo udana pierwsza proba z nowym aparatem - oby jak najwiecej podobnych postow!

Hi Michal,
This photo shows that simplisty of compostion really works well. Basic colours and a simple subject and background all compliment each other to create a photo that is easy on the eye and interesting to look at. I can image this photo up on somebody's wall somewhere.
Great photo.

very nice and iriginal, TFS Ori

Hello Michal,
Interesting indeed!
And a very good subject for the fine graphical shot...
Close-up work well done, good details!

Hello Michal,
Unusual capture on TN.Bright lighting,simple BG,framing,details and composition are wonderful.

Hi Michal,
An excellent shot showing the intricate detail and construcion of this shell. The shot is perfect, and the informative and educational notes are really what this site should be about. Well done!

Hi Michal,
Interesting posting indeed. First as a document and also for the structurated picture itself. A good first shot with your new camera.

Hi Michal,

a very nice and good biology small course, and very original.
congratulation on your camera, i think i wll sell mine and i will buy an 400D (i think :) ). just waiting for other contribution with this new toy.

I like it. TFS Michal.

Jak widac nowy sprzet sprawdza sie znakomicie. Proste bardzo fajne zdjecie i ciekawa notka. Ramka zamyka fajnie kompozycje.
Super :-)

Hello Michal,
this is quite the post, you right this is unlike others and I have to admit I necver seen one looking like this.
You presented this shell so well, excellent sharp details and very well placed into this simple frame. The neutral colors BG does show of the details vewry nicely.

Hi Michal,
Very original picture with a great light. Good registration of this shell, very well composed with a good background and sharpness. Informative, interesting note.
Regards, Ruud

Zdravo i bravo Michal!
Very unique photo.Excellent idea.
Congrats and thanks.
With best wishes,

Yes. It's mine. I cut it and lost it. Please send it back to me immediatly.
Seriously, strange place to find a cut specimen ! Live is mysterious.
With a ring flash, you can avoid the disturbing shadows. It is expensive. I don't have it neither.
Subject is pretty sharp detailed and colorful anyway.
Interesting biology class too.
success further with your new camera.

Hello Michal, this is a good shot. I really like it. The structure that erosion/cutting has revealed is very interesting. My only suggestion here would be to put the shell on diagonal and shoot in portrait mode. Very well done.

A very good slice of a Cerithium shell Michal, I would like to suggest that you take a look into my account, you will find a similar shell against a dark background...
