Abstract Electrocatalytic nitrogen (N 2 ) reduction reaction (eNRR) is a promising route for sustainable ammonia (NH 3 generation, but the eNRR efficiency dramatically impeded by sluggish kinetics. Herein, inspired dynamic extension‐contraction of sea anemone tentacles in response to environmental changes, we propose biomimetic elastic Mo single‐atom protrusion on vanadium oxide support (pSA Mo/VOH) electrocatalyst featuring symmetry‐breaking site and an Mo−O 4 pyramid efficient eNRR. In situ spectroscopy theoretical calculations reveal that protruding Mo‐induced structure optimizes d‐electron filling Mo, enhancing back‐donation π* antibonding orbital, effectively polarizing N≡N bond reducing barrier from *N H. Notably, pyramidal pSA provides microenvironment during continuous processes. This electronic sites based different intermediates, adsorption various N intermediates maintaining low barriers throughout six‐step hydrogenation process. Consequently, Mo/VOH exhibits excellent NH yield rate 50.71±1.12 μg h −1 mg Faradaic 35.38±1.03 %, outperforming most electrocatalysts.
