Simnia spelta

(

)

... that the colour of the sea snail Simnia spelta varies, but when it grazes on the white gorgonian (pictured) it is normally white?

The length and date both check out fine, and there is no close paraphrasing with the English language source (albeit more or less a database entry) the other sources are in French, so I AGF. The hook suggests to me that the whole snail would appear white, but the article seems to imply that actually the shell would be unaffected by grazing on this? Could you clarify?

The last paragraph of the Ecology section does say that the sea slug mimics the white gorgonian when feeding on it and I think this must be the appearance of the shell not just the colour of the mantle. Perhaps ALT1 would be better. Cwmhiraeth (talk) 10:24, 31 December 2014 (UTC)

ALT1 ... that the colour of the sea snail Simnia spelta varies, but when it grazes on the white gorgonian (pictured) it mimics the twigs?

Just wanted to explain that is is a standard thing for Simnia species (actually this is true of many ovulids) to match the color and patterning of the food species on which they live. It is also important to realize that in ovulids the mantle routinely completely covers the shell, unless the animal has been disturbed or distressed in some way, which will cause it to retract the mantle to lessen the impact of a predation attempt. In some ovoids the color of the shell matches the color of the food species on which the animal lives; in other ovulids the color of the shell is white no matter what the color of the food. I don't know what is the case in this species, although most images of this species show a white shell, a few images show a pink shell. Invertzoo (talk) 17:19, 2 January 2015 (UTC)

Review needs completion, including a check of the ALT1 hook. BlueMoonset (talk) 22:22, 17 January 2015 (UTC)

I can't see in the sources where the two organisms are linked.....Cas Liber (talk · contribs) 13:28, 24 January 2015 (UTC)

Try the "Divers biologie" section near the bottom of the DORIS source. Cwmhiraeth (talk) 06:19, 25 January 2015 (UTC)

aah yes, didn't scroll down enough. ok - in sources. good to go with ALT1. Cas Liber (talk · contribs) 13:24, 25 January 2015 (UTC)
