This work presents a database of weights of normal internal organs for the
blue penguin, Eudyptula minor. During a necropsy study of 213 adult and fle
dged immature blue penguins, external body measurements and internal organ
weights were recorded. The relationship between organ weights and body weig
hts shows that the liver and abdominal fat pad are most closely correlated
with the body mass index, a quantitative indication of adequacy of conditio
