Barnacle cyprids. Order Cirripedia.

Left to right: barnacle cyprid (1.7mm) from pump sample, light- and darkfield views of settled vent cyprids (850-900μm)

Size under dissecting microscope: various from ~600µm - >1mm
Size under compound microscope: same
We have found a variety of cyprids in our plankton samples, most (and perhaps all) non-vent. The only vent species at 9°N is Neolepas zevinae Newman, 1979; nothing is known about its larval life, but a few newly settled cyprids were recovered on our settlement blocks (Mullineaux et al., 2003) which presumably belong to this species. Several of these are pictured above (second and third photos).
