| 31. | The gubernaculum is another organ of the nematode male copulatory system, which guides the spicules during copulation.
|
| 32. | The front legs of the male hang loosely and intromission takes the form of a " copulatory jump ".
|
| 33. | Post-copulatory female mimicry by the male offers an advantage by acting as a mate-guarding mechanism.
|
| 34. | Adaptive function of female copulatory calls in primates and research on the subject is still in its early stages.
|
| 35. | The copulatory apparatus of " Supramontana " has a permanent penis papilla and a long common ovovitelloduct.
|
| 36. | At the end of each male pedipalp is a spoon-shaped cymbium that acts to support the copulatory organ.
|
| 37. | The first and second abdominal pleopods may be modified in the male to form gonopods ( accessory copulatory appendages ).
|
| 38. | Female spiders have a dark patch ( epigyne ) on the underside of their abdomen that includes the copulatory organs.
|
| 39. | This tube is the vagina or copulatory channel, and is cemented to the upper wall of the female channel.
|
| 40. | Courtship displays allow the mate performing the selection to have a means by which they can base their copulatory decision.
