Maybe you will sleep better now , maybe not  : In " A Conchological
Iconography - Family Haliotidae " Daniel Geiger gives no explanation for the
size variation ( my guess is that it is probably related to diet ) in
Haliotis tuberculata and there is no statistic study   either about  size
around Gibraltar . In southern Mediterranean there are records of the
species from Morocco , Algeria , Tunisia , Lybia and Egypt . As far as H.
stomatiaeformis is concerned I could youd send you color photos and I might
have some spares though I do not have any live-taken specimen y collection .
I have some color photos of the recently described  Haliotis mykonosensis if
you want . Franck Frydman

Subject: and what about abalones


After the heroic description of the differences between two scallops, I find
now an other tremendous subject, one of those able to delete any ability to
sleep: Haliotis tuberculata Linnaeus, 1758...

This shell varies in size from NW to SE of its range.
Why ?
Big specimens can be found along the Altantic coast of Spain & Portugal, and
small adults appear as soon as the Gibraltar strait has been passed trough.
Is there a place where big and small adult coexist, or is there a quick
variation in size near Gibraltar ?
Any Morrocan records ?

Any idea? Any pictures ? Any material to share with me ?
And what about this little abalone from Malta ? any pics somewhere ?

Thanks in advance
