[[Image:Gastrotrich.jpg|250px|thumb|A mature [[gastrotrich]], with visible cells on the surface. Further growth now occurs by cell enlargement only]] '''Eutelic''' organisms have a fixed number of [[somatic cell]]s when they reach maturity. The exact number is constant for any one [[species]]. Development proceeds by [[cell division]] until maturity; further growth occurs by cell enlargement only. Most eutelic organisms are small or even microscopic: examples include the [[nematodes]] like [[ascaris]], [[gastrotrich]]s, [[rotifer]]s, [[tardigrades]] and [[dicyemida]]. == Other websites == *[http://www.stanford.edu/~ashishg/robert-williamson-eutelic.html List of eutelic animals and other eutelic websites] [[Category:Cell biology]] [[Category:Developmental biology]] {{biology-stub}}
