Elastomeerid

Elastomeerid is a term found in speculative biology and worldbuilding contexts to denote a hypothetical group of soft-bodied invertebrates characterized by unusually elastic tissues. It is not recognized in formal zoological nomenclature, and no species in this group have been described in major taxonomic databases. The elastomeerid concept is used primarily as a thought experiment or narrative device rather than as a scientifically established lineage.

Taxonomy and status can vary between authors. Because there is no formal diagnosis or shared definition, elastomeerid has been proposed at different ranks—sometimes as an order, sometimes as a family—but none of these proposals has gained broad acceptance. Consequently, elastomeerid remains an informal, undocumented construct within current science.

Morphology and physiology are also inconsistent across depictions. In speculative descriptions, elastomeerids possess an elastic, gelatinous integument, a hydrostatic skeleton, and musculature that allows substantial deformation without damage. Sensory, digestive, and circulatory systems are imagined to be simple or compact, with locomotion achieved through body undulations, limb-like appendages, or other deformable mechanisms. These features are not standardized and vary by source.

Habitat and ecology in fictional accounts typically place elastomeerids in aquatic or semi-aquatic settings, including marine sediments, freshwater environments, or planktonic realms. They are often portrayed as grazers, detritivores, or filter feeders, with life cycles ranging from direct development to short, larval stages.

Significance is largely in the realm of conceptual discussions about tissue elasticity, biomimicry, and worldbuilding. In real-world science, elastomeerid has no formal standing, and researchers rely on verified taxa with established nomenclature for study.
