Superphylum
A superphylum is an unofficial grade in taxonomy, above the phylum and below the subregnum, used to describe a group of phyla which probably evolved from a common ancestor.[1]
It is used especially in the animal kingdom. Examples:
- Ecdysozoa
- Lophotrochozoa
- Radiata
- Deuterostomia
- Bilateria
- Planctomycetes-Verrucomicrobia-Chlamydiae (PVC)[2]

Amoeba proteus, visible are the contractile vacuole (circular) and the nucleus (somewhat dumbbell-shaped)
Scanning electron microscopic image of Podomonas kaiyoae grown under axenic conditions. AF, anterior flagellum; PF, posterior flagellum; T, tusk. Brackets indicate the acronemes. Arrows and arrowheads indicate the pseudopodium. Scale bar = 5 μm.
Aplanochytrium, Ectoplasmic network forming basket structure surrounding vegetative cells. This characteristic is unique to members of the genus Aplanochytrium.

Desmarella moniliformis (DIC image)
Ciliate: Paramecium bursaria Her. It has a mutualistic endosymbiotic relationship with green algae called Zoochlorella. The algae are clearly visible in ciliate cytoplasm. Light microscopy, differential interference contrast (DIC)
