Source and fate oflipids in polar gelatinous zooplankton
The presence or absence of accumulated lipids in arctic and Antarctic medusae and ctenophores was determined by visual examinationof living specimens with a dissecting microscope. Lipid accumulations were obvious because of their high refractive indices. Lipids were seenin many of the 200+ gelatinou...

The presence or absence of accumulated lipids in arctic and Antarctic medusae and ctenophores was determined by visual examinationof living specimens with a dissecting microscope.

They always consisted of various-sized droplets and larger masses withinthe lumen of the gastrovascular system. No true depot lipids or adipose tissue were present. The accumulation of lipids was observed infeeding animals, suggesting that the prey-derived lipids were unmodified.
