isolatorids
Isolatorids are a proposed,controversial concept in protozoology describing a putative clade of unicellular eukaryotes distinguished by pronounced cellular compartmentalization and strict intracellular isolation of metabolic processes. The term is not recognized as a formal taxon in major databases, and there is no broad consensus on their delimitation or evolutionary position.
Isolatorids are described as small to medium cells, roughly 5–40 micrometers in diameter, with a rigid or
Reported occurrences span freshwater and marine environments, often in microhabitats with low nutrient availability. Their ecological
There is no formal taxonomic status for isolatorids. Some authors have speculated about affiliations with established
The term arose in late 20th to early 21st century discussions about cellular organization in unicellular eukaryotes.
