Exempel på hur man kan använda ABORAL i en mening

• The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates.
• There are no tentacles but there are a row of branched papillae, forming a figure of eight around the aboral tip.
• The arms are elongate and have both a primary web, forming most of the webbing, and a secondary web connecting the primary webbing to the aboral (outer) faces of each arm.
• It is visible as a small red or yellow button-like structure, looking like a small wart, on the aboral surface of the central disk of a sea star or sea urchin or the oral surface of Ophiuroidea.
• The foundation of the tooth is prolonged lingually with a circlet button and a basal tubercle on the oral and aboral surfaces individually.
• Commensal associations sometimes play part on this echinoderm's life; animals such as Periclimenes shrimp are sometimes found commensally on the oral or aboral surface of the animal, picking up mucus and detritus.
• This ctenophore differs from all previously described lobate ctenophores in two major ways: (1) all of the meridional canals have blind aboral endings, and (2) the body is penetrated by a deep notch located between the adjacent subtentacular comb rows at the level of the infundibulum.
• The cuticle is covered on both the aboral (upper) and oral (lower) surfaces by a latticework of ossicles which are either flattened or rounded plates, or pseudopaxilliform (peglike) plates with broad bases.
• The aboral (upper) surface is covered with plates, each bearing fifteen to thirty small, blunt spinelets known as paxillae.
• Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray, known as an ambulacrum.
• The aboral surface is scattered with small conical spines (that supposedly never enter the papular zones) and the oral (under) surface has small granulations and is clad in large conical tubercles, those nearest the ambulacral grooves and the margin being ovate in cross section and the largest.
• Comasterids are also unique among feather stars in other respects: some species in several genera have the centrodorsal, the aboral skeletal plate, reduced and bearing few or no anchoring hook-like cirri; whereas all other feather stars have symmetrical rays, many reef-dwelling species that live semi-cryptically exhibit a secondary bilateral symmetry in addition to the displaced mouth; arms that arise on one or more rays on the side closest to the mouth are longer than those on the other side.
• Other characteristics include the presence of suckers on the distal portion of arms IV where there at no photophores present; the tentacular club has two rows of hooks and no marginal suckers; on the buccal crown there are typical chromatophores on the aboral surface but on the oral surface there may be some light skin pigmentation.
• The medusae bud off at the base of the hydrants, though where aboral tentacle are present these are located between the stolons and the budding sites.
• At the center on the aboral side is the madreporite—a perforated platelike structure, and on the interambulacra are the four tiny genital pores.
• They develop on the aboral part of the hydranth below the tentacle-covered region, either directly on the hydranth or on spindle-shaped blastostyles.
• This sea star can be distinguished from very short superomarginal plates, the colour of aboral side, the colour of inferomarginal spines and size.
• The aboral (upper) surface is formed of calcareous plates densely covered with paxillae, peg-like projections covered in tiny spinelets.
• mamillatus has less petalloid aboral ambulacral zones than its sister species, and fewer pore pairs per ambulacral plate (9-12 versus 15-16).
• Ciliature on the body is restricted to a posterior wreathe called the "trochal band," made up of three rings of cilia girdling the aboral region of the cell.
