| Abstract | |
The external and internal morphology of Calliostoma adspersum, C. depictum and C. hassler, from Brazilian coast, was studied. Tegula viridula was also analyzed as outgroup. Anatomical characteristics that differentiate all species were found. The major differences were found mainly in the structures: shell; color and papillaes foot; odontophore musculature; anterior esophagus; stomach; spiral caecum and intestinal looping. Calliostoma, according to preliminary data, differentiates from other Trochidae in presenting: reduction or lost of cephalic lappets; pseudoproboscid; renal ampolla; intestinal looping outside haemocoel and m1d odontophore muscle (AU) | |
