Arbacia lixula (peristomial edge)
Description Peristomial edge: The widened pore zones of each ambulacral column protrudes into the peristome, and the interambulacra are indented by the broad, shallow buccal notches, bordered by "tags" (arrow). This gives the peristomial edge a sinuous appearance.
Scale 10 mm.
