Hello Krzysztof,
this is a surprising pic, well done, of an animal that few people will ever see. Thank you for presenting Saduria to us, even dead it looks unusual. Thanks also for the detailed text, the pic looses much if no context is given.
Cheers, Dietrich

Hello Krzysztof,
Wonderful capture and collage.I liked POV,cross framing,lighting,clear details and presentation a lot.

Hola Krzysztof,
Excelente e interesante toma con gran definición y mucho detalle. Un cordial saludo

I seems that I am looking to some kind of live fossil :)
Interesting documentation of something I will probably never have seen if you did not shot it to me. Both shots are very clear and with good quality.
Thanks and regards.

For me, everything from the sea is new and exotic [even if dead :-)!], Krzysztof.
The images are very sharp and rich in details on the creature's upper body. Your precise note helps a great deal in understanding this creature from the deep.
Thanks and take care.

Czesc Krzysiek!

Nie ma to jak Isopoda jednak :-) Bardzo ladna jakosc zdjecia, kompozycja z kamieniami i pokazanie drugiego zblizenia to tez dobry pomysl. Ciezko byloby sfotografowac takiego w srodowisku naturalnym, wiec nawet martwy jest wart prezentacji.

Czesc Krzys,
Very interesting photos. I never managed to find Saduria on the beach, thought once I found a dead one in fish shop in pile of cods. People in the shop were quite shocked when I asked the lady to give it to me with the cod :-)

Taking photos of dead animals may not be one of the TN goals but in this case is completely justified. No way to photograph it alive :-) I haven't seen it either in any sea-aquarium. I think it's not cool enough for broad audience. However for me it's a great beast! And it's the biggest isopod of the Baltic sea too!

Particularly I like the portrait - it's taken with a very good POV.
Great job!

Czesc Krzys!
No prosze, niby martwy zwierz, ale jednak calkiem calkiem. Ciekawy pomysl na fotke, szczegolnie (co zreszta zauwazyli poprzednicy) zrobic takiemu zdjecie na zywo...
Za dobry pomysl wydaje mi sie takze zrobienie zblizenia. Skorupiakow na TN poza krabami prawie nie ma, tym bardziej taka fotka cieszy!

Very good picture of interesting animal. It is just the way to learn more about nature.
The picture is very good technically - nice colours very good sharpness. That's the pity that it doesn't have abdomen, but you couldn't change it ;)
So even without part of the body it is very good.
Best wishes

Oryginalny portret. Ciekawe - że widać każdy martwy detal a jednak jakoś nie jest obleśne :-) To już Sztuka przez S!

Hi Krzysztof,
A very unique creature. A new one for me. A nice composite of the two views to show us the intricate detail. Well done!

Hello Krzysztof,
Excellent shots of this interesting creature!
The composition, the colours, the patterns and textures are very beautiful. Very sharp too. Nice find!
TFS and regards, Ulla

Hi Krzysztof.
Very well known and pleasant to marine views. You have pictured this one perfectly. Outstanding reproduction of all features of this animal: colours, texture and form. Excellent sharpness and details of the image, impressive lighting, nice note. Superb done and my best regards.

Hello Krzysztof,
clear, well composed, aesthetically pleasing presentation of marine life that is rarely shown here on TN. I like the combination of the two images, the repetition creatres a nice rhythm.
Thank you! Best regards,

Bonjour Krysztof, bonne et heureuse année 2007, avec un peu de retard!! je ne connaissais pas cette espèce de crustacés isopodes proche de nos "cloportes" le Porcellio dilatatus!! leur taille semble plus grande. Félicitations pour cette macro partagée, Didier.

Eres increible Krzysztof !!!!! Acabo de publicar la mariposa y ya me la has identificado; muchas gracias por tu colaboración y buena disposición.
Tu fotografía un excelente documento con buen formato y presentación, destacando tanyto la luz como el preciso enfoque.
Un abrazo: J. Ignasi Tejedor
