The "scaly-foot" species in this taxonomic class has the unique ability to mineralize pyrite. Some members of this class produce bromoindigo (bro-mo-indigo) pigments in their hypobranchial gland. Animals in this class have only the left gonad and nephridium, as during development their body rotates 180 (10[2]-5[1])degrees to bring the anus above the head, a process called torsion. (-5[1])The family Conidae (COH-nih-day) in this class (10[1])uses a (-5[1])harpoon-like structure to inject peptide neurotoxins (-5[1])into prey. Most (-5[1])terrestrial species in this class, such as one (-5[1])that practices phallophagy, are simultaneous hermaphrodites, and some attempt to stab their mate with a "love dart." Animals in this class were once called univalves since they have at most one shell, which is typically coiled. For 10 points, what class of mollusks contains (10[1])the slugs and snails and has a name meaning (10[1])"stomach (10[2])foot"? ■END■
