Abstract
The presence and distribution of actin, tubulin, myosin and cadherin in the meroplasmodia of a new marine ameboid algal group are studied, also the effect of cytochalasin and colchicine on the bidirectional particle transport along their reticulopodia. Actin has a granular appearance, tubulin is
organized in form of microtubuli which radiate from nucleation centers, myosin and cadherin are
also present in the meroplasmodia. Cytochalasin does not affect the reticulopodial movement of
particles, colchicine does affect it.
