    "abstract": "We investigate the self-locomotion of an elongated microswimmer by virtue of\nthe unidirectional tangential surface treadmilling. We show that the propulsion\ncould be almost frictionless, as the microswimmer is propelled forward with the\nspeed of the backward surface motion, i.e. it moves throughout an almost\nquiescent fluid. We investigate this swimming technique using the special\nspheroidal coordinates and also find an explicit closed-form optimal solution\nfor a two-dimensional treadmiler via complex-variable techniques.",
