The nucleotide sequences of 5S rRNAs from two Annelida species, Perinereis brevicirris and Sabellastarte japonica, and an Echiura species, Urechis unicinctus have been determined. Their sequences are all 120 nucleotides long. The sequence similarity percents are 88% (Perinereis/Sabellastarte), 90% (Sabellastarte/Urechis) and 92% (Perinereis/Urechis), indicating that the Echiura is indistinguishable from the Annelida by their 5S rRNAs. The 5S rRNA sequences from the Annelida/Echiura are most related to those from the Nemertinea (87%), the Mollusca (87%) and the Rotifera (88%).
