According to Figure 34.22 and the accompanying text, which of the following statements about amphibian orders is INCORRECT?

  • A: Urodeles, like salamanders, retain their tail as adults.
  • B: Anurans, including toads and frogs, typically lack a tail as adults.
  • C: Apodans, or caecilians, are legless and burrowing amphibians.
  • D: All amphibians maintain gills throughout their adult life stages.
