Morphotype
The term morphotype (in English morphotype) is used in biology and medicine to delimit similar, but morphologically different units. Application examples are the delimitation of morphologically distinguishable tumors , morphologically distinguishable cells of a cell type, for example large and small nerve cells , and the classification of human egg cells .
In microbiological taxonomy , the science of the systematics of microorganisms, “morphotype” is a unit below a subspecies . For example, it defines a bacteria - trunk or a bacteriophage strain which can be distinguished from other strains of the same species by morphological features, such as due to different cell sizes or surface structures.
“Morphotype” is also used in higher organisms, for example in black flies with different larval forms of a species, in dolphins of different sizes or in plants ( nodding wood sorrel ). In higher organisms, however, “morphotype” is used more in the more general meaning “different form” than as a taxonomic unit below a subspecies. So z. In the case of crustaceans ( Crustacea ) , for example, the squat crab shape of various taxa or the peculiar physique of slippery crabs ( Scyllaridae ) are each described as a separate morphotype.
