Intrafiber lipid droplets in swimming skeletal muscle of stranded cetaceans in Canary islands
The present study is focused on the analysis of swimming skeletal muscle samples (longissimus dorsi) from 15 different species of 86 stranded cetaceans in Canary Islands from 1996 to April 2004. The purpose of this study was to evaluate the presence of spherical intrafiber lipid droplets to explain...
