Note
The lipid content of sea anemones from central California was measured over a three-year period by ether extraction. These levels were significantly above those which would he considered as solely structural and they cycled in a manner roughly paralleling the reproductive cycle. The lipid content was shown to be independent of sex, and directly proportional to size of anemone. Animals from the thermal outfall canal of a power plant had lower levels of lipid than control animals, although these levels rose to equal control values during periods of decreased power plant activity. There was no effect of a one-month starvation on the lipid content in anemones from either site.
