Amoebae move by crawling over a surface (cell crawling), which involves . localized contractions driven by myosin and microtubules growth of actin filaments to form bulges in the plasma membrane assembly of microtubule extensions that vesicles can follow in the direction of movement reinforcement of the pseudopod with intermediate filaments
