| An example used by both Schmalhausen and Waddington concerns the calluses on the keels and sterna of ostriches. |
|
| There is a rather extensive membranous area separating the sterna of the mesothorax and the metathorax. |
|
| Examination of the sterna and abdomina of these crabs permitted identification of mature and immature males and females. |
|
| After cutting the pleural membrane between the sterna and terga, it was possible to remove the entire genital apparatus with a fine-tipped forceps. |

| Changes in shell dimensions of pearl oysters, Pinctada mazatlanica and Pteria sterna, during growth as criteria for Mabe pearl implants. |

|
| Abdominal sterna II, III and lateral parts of IV heavily punctured, the others without punctation, covered with short, appressed macrotrichia, some parts pruinose. |
|
| A recent analysis of DNA sequences supported the splitting of Sterna into several smaller genera. |
