Where does the great crested newt spend its time and what is its larval respiration?

• A. In land; adults breathe with lungs.
• B. In water; larvae breathe with gills.
• C. On land; larvae breathe with lungs.
• D. In water; larvae breathe through skin.

Answer: (B)

Amphibians switch from an aquatic larval stage to a more terrestrial adult stage, with different breathing methods at each life stage. Great crested newt larvae live in water and breathe using gills, which is why the correct description notes an aquatic larval environment and gill respiration. The other options misstate the larval environment or how larvae respire (lungs or skin-only respiration for larvae aren’t the typical pattern here), even though adults may use lungs and skin for gas exchange.
