Today I dedicate this piece of stone to Marie (mariki) for her wonderful imagination. Great quality Marie and I like it very much. Thank you very much.

A barnacle is a type of arthropod belonging to infraclass Cirripedia in the subphylum Crustacea, and is hence distantly related to crabs and lobsters. Barnacles are exclusively marine, and tend to live in shallow and tidal waters, typically in erosive settings. They are sessile suspension feeders, and have two nektonic larval stages.

Around 1,220 barnacle species are currently known. The name "Cirripedia" is Latin, meaning "curl-footed".

Barnacles are encrusters, attaching themselves permanently to a hard substrate. The most common, "acorn barnacles" (Sessilia) are sessile, growing their shells directly onto the substrate. The order Pedunculata ("goose barnacles" and others) attach themselves by means of a stalk.

Most barnacles are suspension feeders; they dwell continually in their shell - which is usually constructed of six plates - and reach into the water column with modified legs. These feathery appendages beat rhythmically to draw plankton and detritus into the shell for consumption.

Other members of the class have quite a different mode of life. For example, members of the genus Sacculina are parasitic, dwelling within crabs.

Barnacles are always marine. While they have been found at water depths up to 600m, most barnacles inhabit shallow waters, with 75% of species living in water depths of less than 100m, and 25% inhabiting the intertidal zone. Within the intertidal zone, different species of barnacle live in very tightly constrained locations, allowing the exact height of an assemblage above or below sea level to be precisely determined.

Since the intertidal zone periodically desiccates, barnacles are well adapted against water loss. Their calcite shells are impermeable, and they possess two plates which they can slide across their aperture when not feeding. These plates also protect against predation.

Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Crustacea
Class: Maxillopoda
Subclass: Thecostraca
Infraclass: Cirripedia

Hello Haraprasan,

nice piece of stone with Barnacles, good details and very sharp.

Gert

Nice DOF and exposure. I can even see the little bugs on the side.

Best regards,

Hi Haraprasan, amazing capture of this tidal zone stone which shelter so many barnacles (I think Balanus sp.) of various sizes. Also I can see some mollusc shels (Carduelis sp.) a bonus:) Perfect composition and worthy dedication to our joint friend Marie my friend! Well done! TFS.
Cheers,

Bayram

Hello Hara,
A fine and unusual capture of a Barnacle covered stone on the intertidal beach. Great to see this in its natural environment and taken with great sharpness and lighting. The image is so sharp that small flies are also visible on the stone, a bonus that our TN friend Mariki would appreciate in this excellent tribute to her.
TFS this superb contribution to TN,
Ivan

Lovely shot, HP!
Cheers!

Hello Haraprasan,

Thank you for the dedication. Very beautiful stone with barnacles. Excellent sharpness and wonderful colours. Superb detail. The sea world is something I am familiar with because I spent the 20 first years of my life close to the sea in Brittany (France) and I go back at least twice a year there to see my parents.
Cheers,
Mariki

All I knew about Barnacles was that they were some kind of precious stone, HP. I could be wrong even on that count!
I am stunned at the appearance of this "stone" which throbs with marine life.
My experience of living by the sea has been very very limited, so I am intrigued by such life forms.
It is a beautiful picture.
TFS.

Hola HP,
What a beautiful post, just right to warm our hearts in these spring days my friend, your cirripeds look quite content out of water, safe behind their tightly closed shells but your fine "stone" also harbour some sponges, tunicates and molluscs, however for me one of the most intriguing inhabitants is the whitish, lacey bryozoon colonies. Surely a haven in itself HP, our adorable friend Marie will love this, I'm sure.
Cheers,
Mehmet

Hi HP,
I appreciate you hunt for these unique forms of life and these are such treasures to be shared. This is a capture one does not usually come across quite humming with life. Your notes and the Mehmet's critique adds a lot of information. One is thus able to appreciate the true beauty of this wonderful cpature which is also an apt dedictation for Marie.
very well done.
TFS & Cheers

Hello Haraprasan
This is an unusual looking post.
The pov is very good and the barnacles show well.
Lovely colours with pinks and light reds accenting the shells.
Well focused with very good detail.
