'''Reinhardt Møbjerg Kristensen''' (born 1948) is a [[Denmark|Danish]] [[invertebrate]] [[biologist]], noted for the discovery of three new [[phylum|phyla]] of microscopic animals: the [[Loricifera]] in 1983, the [[Symbion|Cycliophora]] in 1995, and the [[Limnognathia|Micrognathozoa]] in 2000. He is also considered one of the world's leading experts on [[Tardigrada|tardigrades]]. His recent field of work revolves mostly around [[arctic]] biology.

He is also known for documenting ''[[Dendrogramma]]'', an invertebrate genus that was later classified as [[Siphonophorae]] of the family [[Rhodaliidae]].<ref name="OHara">{{cite journal|last1=O’Hara|first1=Timothy D.|last2=Hugall|first2=Andrew F.|last3=MacIntosh|first3=Hugh|last4=Naughton|first4=Kate M.|last5=Williams|first5=Alan|last6=Moussalli|first6=Adnan|title=Dendrogramma is a siphonophore|journal=Current Biology|date=June 2016|volume=26|issue=11|pages=R457–R458|doi=10.1016/j.cub.2016.04.051|pmid=27269719|doi-access=free}}</ref>

== Loricifera ==

Kristensen collected the first members of the [[Loricifera]] phylum in [[Roscoff]], France, in 1970, but did not describe it until 1983.<ref name=Heiner2005>Heiner, I. 2005. Preliminary account of the loriciferan fauna of the Faroe Bank (NE Atlantic). Biofar Proceedings 2005: 213–219.</ref>

== Cycliophora ==
Kristensen and [[Peter Funch]] described ''[[Symbion pandora]]'', on the mouth-parts of Norwegian [[lobster]]s, in 1995; other species were later found on other types of lobsters.

== Micrognathozoa ==
Kristensen described ''[[Limnognathia maerski]]'', the first (and so far only) known species in the group, in a cold spring on [[Disko Island]] in 2000.
