Almost all multicellular critters known (animals, plants, fungi, algae) go through a microbial stage in their life cycle – gamete or spore. Can you think of a multicellular species or higher taxon that has NEVER been caught going through the microbial stage?
perhaps the bedelloid rotifers might fit your profile? bdelloid rotifers reproduce by parthenogenesis. oogenesis proceeds via two mitotic divisions. meiosis is absent, and therefore there is no stage during which chromosome reduction occurs; i.e. no haploid stage.
