This species is encountered frequently in northern Norway. It is a boreal species found in hard bottom habitats from 9 meters depth. These specimens were found at 40 meters depth in an area with relative strong currents. C. islandica is very mobile as it can swim for short distances. Have seen old specimens with sponges, tube-building polychaetas and red algae attached to them, but never in younger animals.
Hi!
Very interesting color in the smallest clam. I had nevere observe something like this in specimens from Russian waters
No, this was shocking to me to. I have never observed any variation in color in this spercies before, even though it is one of the most frequently encountered species in hard bottom fauna samplings here in northern Norway. I wonder what caused this anomaly in this specimen. Also funny that it looks as if it had been painted due to the unusual pattern of colors.
Camilla, Would it be possible to see another image of your specimen again? However, this time with the exterior surface dry. Thank you. Bret
I think I still have the specimen in my collection. If I find it I will take more pictures.
Thanks for checking. I am curious if there are any deviations in the sculpture as well?
I have seen a number of different shades of color - reddish, yellowish, rust, orange, grayish - however, I have never seen one with a pattern, especially like this one.
Do you know the chain of ownership? Might it be a doctored specimen?
In Indonesia, we have an Asian moon scallop, Amusium pleuronectes. I have never seen a variation of colour.
Is the variation of colour in Chlamys islandica happened in a large number and in a large regions or just in a few number? is there any changement in an ecological parameters ?
The smallest specimen looks to me a specimen of Palliolum tigerinum.
