We have used acetic acid‐urea‐triton (AUT) gel electrophoresis and ionic exchange chromatography in order to analyze the interspecific, variability and microheterogeneity pattern of the protamine‐like (PL) protiens of the sperm or 4 different species or the bivalve molluse, Mytilus . We have found that based upon these 2 criteria, it is possible to unambiguously distinguish each species from the rest. We have thus been able to corroborate the identity or M. irossulus , We have also analyzed the amino acid composition of some of the PL components for each different species, In the case of the PL‐11* fraction, we have analyzed the composition of its major protein subcomponents.
