Hi Ross

I recently received a box of 61 P. hirasei. Every one had at least 5
large pinkish balanomorph (acorn) barnacles attached. Some were
really bristling with them. Most of the specimens were
live-colllected.

I have one Bayerotrochus africanus with bases of several balanomorphs
up to 1cm diameter.

None of my other specimens have evidence of having borne barnacles:
P. atlanticus (1)
P. hirasei (2)
P. salmiana (1)
P. vicdani (1)
P. gotoi (1)
E. rumphii (2)
B. africanus (2)
B. teramachii (2)

None of my NZ fossil Perotrochus & Bayerotrochus spp show any signs
of barnacles.
