Characterization of cortical alveoli content in several species of Antarctic notothenioids
Cytochemical analyses was used to study the organization and content of cortical alveoli in eight species of Antarctic teleosts belonging to three different families of notothenioids: nototheniids, bathydraconids and channichthyids. Results indicated differences existed among the various species in...
