aboral การใช้

• It has short paxillae that give the aboral surface a granular appearance.
• On surfaces, they move laterally, with the aboral surface facing the substrate.
• Planula larvae swim with the aboral end ( the end away from the mouth ) in front.
• Their name comes from the presence of numerous low spines on the aboral ( upper ) surface.
• Finally, five lateral canals run along the inside of the test and converge at the aboral pole.
• The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.
• The anus is situated on the upper ( aboral ) surface of the test, directly opposite the mouth.
• Similarly, a new anus forms on the right side, which becomes the upper, or aboral, surface.
• The left side of the larval body becomes the oral surface of the juvenile and the right side the aboral surface.
• This is a skeletal plate, or sieve, opening to the water vascular system, located on the aboral surface.
• The gonophores in the family Corymorphidae are borne above aboral tentacles, either directly issuing from hydranth wall or on blastostyles.
• The argonaut was seen holding on to the aboral ( exumbrellar ) surface of the jellyfish using its lateral and ventral arms.
• The left hand side of the larva develops into the oral surface of the juvenile while the right side becomes the aboral surface.
• The Aboral / Oral axis ( analogous to the dorsal / ventral axes in other animals ) is specified by a Nodal homolog.
• The aboral surface of the body is studded with plates of calcium carbonate, forming an endoskeleton similar to that in starfish and sea urchins.
• 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
• They develop on the aboral part of the hydranth below the tentacle covered region, either directly on the hydranth or on spindle-shaped blastostyles.
• 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.
• Most Platyctenida have oval bodies that are flattened in the oral-aboral direction, with a pair of tentilla-bearing tentacles on the aboral surface.
