wasnt worrying about acorn barnacle but about this gastropods....i cant see the big difference between the 2, but if you are some kind of expert I'll believe you, although i'm pretty sure that' the correct name for the black guy in the photo coz thats the one mentioned in the elementary schoolbook! and i'll be very happy if you would check it in your book ;)
this is what i mean about IDing the barnacle you need to see this bit http://www.comoxvalleynaturalist.bc.ca/a...
i think the two gastropods are different, the whorl of the larger is much more triangular like top shells where as the smaller is more rounded, not a littorina though i was wrong on that might just be becuase its a juvenile that its mishapen but i think they seem different, i have an id book so ill take a look! for barnicles if you can see inside there is usually a different patten on in the closing bit of shell, they are some sort of acorn barnacle though but there are several species.
There aren't thousands of this in Rovinj
The small is the same as the big, there is always next photo is you are not clear what's what!
There are a whole lot of animals in this phot, barnacles and two species of gastropod, the bigger blacker snail is a topshell, and the smaller looks to be a littorinid, for the barnicle you need to be able to see inside the cup to ID it properly.
