In 2006 a new water bear species (Latin:Tardigrada), Echiniscus madonnae was named after Madonna. The paper with the description of E. madonnae was published in the international journal of animal taxonomy Zootaxa in March 2006 (Vol. 1154, pages: 1-36). The authors' justification for the name of the new species was:
"We take great pleasure in dedicating this species to one of the most significant artists of our times, Madonna Louise Veronica Ritchie".
The Integrated Taxonomic Information System (ITIS) number of the species is 711164.
