Only 13 nemertean species have been mentioned for their chromosomes in literatures, but there were no karyotype analyses. The measure technology of DNA content has applied extensively in animal kingdom, but there was only one research concerning the nemertean.
迄今,在已知的1275种纽形动物中,仅13种纽虫有过染色体数目报道,没有任何核型研究;仅一种纽虫的DNA含量得到研究。
