All protists are eukaryotes, some are heterotrophic, some are autotrophic, almost all can move, and almost all are single celled. No, we need traits that ALL of them share, not just some or almost all.
They classified protists into the animal kingdom because they shared more similarities. Protists became their own kingdom in the 1830s. The protists kingdom expanded in 1845.
