(A) Sibling tadpoles grown in 1 mM methimazole for several weeks. Control tadpole (Right) at stage 53 treated for 8 days with 3 nM T3 (Center) and 3 nM T4 (Left). They were stained for cartilage with Alcian blue. (B) Tadpole grown for 2 months in 1 mM methimazole/10 μM iopanoic acid/5 nM T4. In 1 month, the tadpole developed to stage 59 but then did not change further during the final month of treatment.
