brasiliensis, the madreporite and odontophore are homologous to those of other recent, non-paxillosid asteroids, and follow the Late Madreporic Mode.
For the main terminology, including that relating to odontophore muscles, see Simone (2011).
An elongate muscle slip originates on the dorsal surface of the pharyngeal retractor and inserts at the end of the odontophore sac.
Interestingly, although neurons B19 and B110 fire out of phase during rhythmic motor outputs and are involved in different muscle movements, they possess axonal projections that terminate onto similar sets of buccal muscles, which regulate the movements of the radula and odontophore.
On contact with the prey, the predator extends the oral region slightly, exposing the inner lip area, the odontophore is then rapidly thrust forward, the anterior portion with enveloping radula emerging and extending some distance beyond the mouth.
9) % in females, separated from eye by 1 1/2 tympanum diameters; supratympanic fold thick, bearing 1-2 subclinical tubercles; 1-2 subconical postrictal tubercles; ventrolateral edge of lower lip bearing small tubercles, most evident posteriorly; choanae round, not concealed by palatal shelf of maxillary arch; vomerine odontophores median and posterior to choanae, separated medially by distance equal 1/2 width of an odontophore, each larger than a choanae, oval in males, subtriangular in outline in females, bearing up to 6 teeth in a slanted row; tongue oval, posterior 1/3 not adherent to floor of mouth, posterior edge not notched; long vocal slits lateral to tongue, vocal sac subgular.
3 % eye length; a single postrictal tubercle; choanae small, round, not concealed by palatal shelf of maxillary arch; vomerine odontophores median and posterior to choanae, oval, bearing slightly elevated row of 2-5 teeth, separated medially by space nearly equal width of an odontophore; tongue longer than wide, posterior 1/5 not adherent to floor of mouth, posterior edge not notched; vocal slits long, well lateral on floor of mouth; vocal sac subgular.
0 % eye length; 2 or 3 conical postrictal tubercles; choanae not concealed by palatal shelf of maxillary arch, triangular in outline; vomerine odontophores median and posterior to choanae, subtriangular in outline in female, slanted in males, separated medially by distance equal width of an odontophore, bearing a slanted row of 3-5 teeth; posterior edge of tongue notched, posterior 1/5 not adherent to floor of mouth; no vocal slits in males.
Although we can detect the presence of vomerine teeth (using cleared and stained specimens), an odontophore requires some additional structure.
4 % eye length, its anterior and ventral edges elevated, separated from eye by distance slightly greater than tympanum diameter; postrictal tubercles scarcely evident; choanae large, round, not concealed by palatal shelf of maxillary arch; vomerine odontophores oval, median and posterior to choanae, smaller than a choana, separated medially by width of an odontophore, bearing a slanted row of 3-5 teeth; tongue longer than broad, its posterior edge bearing shallow notch, posterior Vi not adherent to floor of mouth; vocal slits long, posterolateral to tongue.
8) % in females; supratympanic fold thin, ending just behind tympanum; two postrictal tubercles, nearest subconical; choanae round, not concealed by palatal shelf of maxillary arch; odontophores median and posterior to choanae, approximately twice size of a choana, subtriangular in outline, elevated, separated medially by distance 2/ 3 width of odontophore, bearing transverse row of up to 4-5 teeth; tongue longer than wide, posterior edge with shallow notch, posterior 1/3 not adherent to floor of mouth; males with short vocal slits posterolateral to tongue.
9, n = 21)% eye length; postrictal tubercles subconical, fused, forming short ridge (most obvious in larger females); in larger females, choanae small, round, not concealed by palatal shelf of maxillary arch; in males and smaller females, choanae larger, partially concealed by palatal shelf of maxillary arch; in larger females, vomerine odontophores median and posterior to choanae, oblique, separated on midline by distance 3X odontophore width, bearing 2-3 teeth, each twice size of a choana; in males, vomerine odontophores usually absent, if present, concealed in tissue of palate (as in immature females); tongue slightly longer than wide, not notched posteriorly, posterior 1/5 not adherent to floor of mouth; males lack vocal slits.
