Abstract

The two Pacific anguilloid sishes Anguilla japonica and Astroconger myriaster, belonging to the different families, appear to have identical chromosome numbers (2n = 38) and karyotypes, including one pair of conspicuous heteromorphic chromosomes in females. Cytophotometric measurements, however, indicate a considerable difference in DNA content between the two species.
