Salinella salveis adubious speciesof a very simpleanimalwhich some have named as the sole member of thephylumMonoblastozoa.It was discovered in 1892 byJohannes Frenzelin thesalt pansofCórdoba Province, Argentinaand cultivated in a laboratory by him. This animal has not been found since and its real existence is considered as doubtful.[2][3]A project involvingMichael Schrödlfrom theZoological State CollectioninMunichsearched forSalinellainsalt lakesacross Argentina and Chile, but failed to find any specimens.[4][5][6]
Discovery
[edit]Salinellawas discovered in soil samples from salt pans aroundRío Cuarto,Córdoba Province, Argentina, although the exact type locality was never specified.[6]
Description
[edit]According to Frenzel's description,S. salveis more organized thanProtozoa,but still very primitive for amulticellular organism.They are characterised by their distinct anterior/posterior parts and being denselyciliated,especially around the "mouth" and "anus". They have only one layer of cells, andreproduce asexuallybytransverse fissionof their bodies. Althoughsexual reproductionwas suspected, Frenzel did not observe it.[7]
