| The aboral surface of the central disc comprises large plates surrounding a single broad central plate. |
| Therefore, in these early stages, the boundary can be drawn between these aboral plates and those formed adoral to the terminals. |
| The position of these plates on the non-rudiment side of the larva suggests that ossicles occurring on the aboral surface are extraxial. |
| Because a key species diagnostic character is the nature of aboral cup plate sculpturing, this specimen cannot be identified. |
| The usual view that radiate forms have become bilateral by the elongation of the aboral dome into the trunk is probably erroneous. |
| When placed on their aboral side in a finger bowl of fresh, ambient temperature sea water, the tube-feet of the sea star are readily accessible. |
