Solar-driven interfacial evaporation is an efficient and environmental-friendly method to produce clean water that has been widely studied. However, its application in high-concentration brines (>= 20 wt% salinity) remains limited by severe salt accumulation. Inspired by the interfacial fluid dynamics of horned lizard skin scales and plant vascular systems, we developed a 3D-printed dual-biomimetic solar evaporator with superior salt resistance. The evaporator integrates bio-mimicked micro-grooves and hierarchical microchannels to address critical salt management challenges. The lizard-skin-inspired micro-grooves generate a self-sustained Marangoni effect, driving directional ion migration to suppress salt crystallization. Concurrently, the plant-root-mimetic microchannels enable rapid water replenishment and reverse ion backflow, maintaining stable evaporation in 25 wt% NaCl brine. Notably, the evaporator delivers a high evaporation rate of 1.65 kg m(-2) h(-1) (96.1 % evaporation efficiency) and sustains 1.18 kg m(-2) h(-1) output over 10 h in high-salinity brine. Outdoor tests further validate the practical viability of our bionic solar evaporators, achieving up to 3.73 L m(-2) day(-1) freshwater production with zero salt fouling in 5 days cycles. This design breakthrough in salt resistance enables reliable operation in extreme salinity environments, advancing scalable solar desalination technologies.
