Rostrate Barnacle

The joints where the plates overlap are shiny.

This is the scutum (left) and tergum (right) from an individual eaten by a seastar. The tergum is beaked, as can be seen at top.

This is the view of the inside of the tergum (left) and scutum (right).

The wall plates are formed of hollow tubes, the openings of which are visible at the bottom of this photo. Longitudinal striations can be seen on the inside of the wall plates, as seen here. The base of the plates is at the bottom.
