Polytactic and orthotactic
Large polypodial amoebae with well pronounced pseudopodia; in fast locomotion monopodial form.

Palmate
Midsize polypodial amoebae with numerous pseudopodia which are formed rom the basal part of the body.

Dactylopodial
Usually small amoebae, wit characteristic finger-shaped hyaline subpseudopodia (dactylopodia).

Acanthopodial
Small amoebae with sharp, tapering, pointed, sometimes furcate, hyaline subpseudopodia.

Monotactic
Monopodial, elongate, amoebae, without any lateral or dorsal wrinkles and with steady cytoplasmic flow.

Rhizotactic
Amoebae in rapid locomotion monopodial, with distinct adhesive uroid and usually with large hyaline cap.

Flamellian
Amoebae elongate to semicircular, flattened, with frontal subpseudopodia, lobes and waves.

Lens shaped
Amoebae lens shaped, dorsal surface covered by a flexible tectum or cuticle.

Striate and rugose
Amoebae oblong or rounded with several parallel dorsal folds and/or with numerous irregular dorsal wrinkles.

Lanceolate or lingulate
Amoebae lancet or tongue like, with lateral flatness, without folds or wrinkles, except Paradermamoeba.

Fan shaped
Amoebae flattened, fan shaped, semicircular or spatulate amoebae, without subpseudopodia.

 

Mayorellian
Amoebae elongate or irregularly triangular, with blunt conical or mamilliform subpseudopodia.

Branched, but not reticulate, pseudopodia without granules
Amoebae flattened, branched without any reticulum. Pseudopodia without granules or only at the base.

Branched and reticulate, pseudopodia without granules
Amoebae flattened, branched with anastomosing pseudopodia. Pseudopodia without granules or only at the base.

Branched and reticulate, with granulopodia
Amoebae flattened, branched with anastomosing pseudopodia. Pseudopodia with bi-directional streaming.

Eruptive
Monopodial amoebae, eruptive in locomotion. Eruptions may be more or less pronounced, but are always visible (distinguish from Rhizamoeba, which also has eruptive traits).

Vampyrellids
Filose amoebae which feed on algae

Mastigamoeba
Amoebae with cilium, usually very long

Pelomyxa
Amoebae oblong or ovoid, sometimes with small cilia

Flabellate morphotype
