- Pedinellales o actinodinos es un pequeño grupo de protistas unicelulares presentes en tanto en agua dulce como en ambientes marinos, la mayoría de los cuales son sésiles, fijándose al sustrato por un tallo posterior. Presentan una morfología de tipo heliozoo, esféricos, con tentáculos o axopodios irradiando a su alrededor. También presentan un flagelo, insertado en la parte anterior de la célula. Parte de los géneros (Pedinella, , y ) son fotosintéticos, mientras que otros han perdido sus cloroplastos y son heterótrofos, alimentándose por fagocitosis de las presas que capturan con la ayuda de sus tentáculos. La estructura de la célula los relaciona con Actinophryida. (es)

- Pedinellales is a group of single-celled algae found in both marine environments and freshwater. These are found in both freshwater and marine environments, and most genera are sessile, attached by posterior stalks. The flagellum is at the anterior of the cell, and the tentacles surround it, often capturing small prey drawn in by its current. The colored genera are Pedinella, Apedinella, Pseudopedinella, and Mesopedinella. Several more genera have lost their chloroplasts and feed entirely by phagocytosis. These are Parapedinella, , and . It also appears that certain heliozoa are actually derived pedinellids. Ciliophrys alternates between a mobile flagellate stage and a heliozoan feeding stage, where the body is contracted with extended axopods all over its surface, and the flagellum is curled up into a tight figure eight. The actinophryids, Actinophrys and Actinosphaerium, exist only in a heliozoan form with no flagellum and with more elaborate bundles of microtubules supporting their axopods. Their inclusion was argued by Mikrjukov and Patterson, who coined the term actinodine to refer specifically to this extended group. Pedinellids were classified as heliozoans by some authors. The colored pedinellids were originally treated as a family of golden algae in the order Ochromonadales, promoted to an order Pedinellales by Zimmerman in 1984. Their relationship to the silicoflagellates became apparent some time later, and Patterson defined this rankless group for the two in 1994. Moestrup treated it as the class Dictyochophyceae, previously restricted to the silicoflagellates, while Cavalier-Smith defined a new class Actinochrysophyceae for them. (en)
