| 11. | The gonophores in the family Corymorphidae are borne above aboral tentacles, either directly issuing from hydranth wall or on blastostyles.
|
| 12. | The argonaut was seen holding on to the aboral ( exumbrellar ) surface of the jellyfish using its lateral and ventral arms.
|
| 13. | The left hand side of the larva develops into the oral surface of the juvenile while the right side becomes the aboral surface.
|
| 14. | The Aboral / Oral axis ( analogous to the dorsal / ventral axes in other animals ) is specified by a Nodal homolog.
|
| 15. | The aboral surface of the body is studded with plates of calcium carbonate, forming an endoskeleton similar to that in starfish and sea urchins.
|
| 16. | The polyp colour is pale pink through to red, and consists of a central circlet of oral tentacles surrounded by paler but larger aboral tentacles
|
| 17. | They develop on the aboral part of the hydranth below the tentacle covered region, either directly on the hydranth or on spindle-shaped blastostyles.
|
| 18. | On the arms these are in four rows with each segment having an aboral and oral shield and two lateral shields, usually with fringing spines.
|
| 19. | Most Platyctenida have oval bodies that are flattened in the oral-aboral direction, with a pair of tentilla-bearing tentacles on the aboral surface.
