Monoblastozoa
Salinella
Species of very simple animal that may not actually exist
Salinella salve is a dubious species of a very simple animal that may not exist, but which some have named as the sole member of the phylum Monoblastozoa. It was discovered in 1892 by Johannes Frenzel in the salt pans of Córdoba Province, Argentina and cultivated in a laboratory by him. This animal has not been found since and its real existence is considered as doubtful.[1][2] Michael Schrödl from the Zoological State Collection in Munich is involved in a project to search for Salinella in Argentina.[3][4][needs update?]
