Now explain how a univalve differs from a bivalve, in more ways than just the number of shells. |
|
In the earliest Cambrian, one lineage developed a bivalved mineralized shell, the other an endogastric univalve shell. |
|
Vetustovermis bears a number of morphological features that are found in Kimberella, which has been interpreted to have a non-mineralized but stiff univalve shell. |
|
The bioluminescent system of the univalve shell Latia neritoides exhibits a luciferin luciferase reaction. |
|
In conjunction with the univalve shell, this has been taken to indicate Kimberella was a mollusc or very closely related to molluscs. |
|
Strain fungus OB-0098 was isolated from an unidentified univalve shell collected on Okinawa main island, Okinawa, Japan. |
