Sarcomastigophora

The phylum Sarcomastigophora belongs to the Protista or protoctista kingdom and it includes many unicellular or colonial, autotrophic, or heterotrophic organisms. It is characterized by flagellae, pseudopodia, or both.[1]

Taxonomy

It is divided into three subphyla: the Mastigophora, the Sarcodina and the Opalinata.[2]

It is polyphyletic, and it is not a universally recognized classification. It places great significance upon method of locomotion in generating the taxonomy.

It can be described either as:

kingdom Protista → phylum Sarcomastigophora

or in older classifications as

phylum Protozoa → subphylum Sarcomastigophora.[3]

Characteristics

It gets its name from the combination of "Sarcodina" (which is an older term used for amoeboids)[4] and "Mastigophora" (which is an older term for flagellates).

The characteristics of phylum sarcomastigophora are :

(1) Nucleus is of one type except in the stages of certain foraminifera.

(2) Locomotory organ either pseudopodia or flagella or both.

(3) Reproduction asexual , but when sexually it is essentially by syngamy

(4) Spore formation is absent.

Example : Amoeba, Euglena etc.
