NATURE ADRIFT 



for Other deep dwelling organisms in the plankton. Sometimes they are 

 abundant quite near the surface and in inshore as well as oceanic waters. 

 The minute calcareous plates catch the sunlight and make the water just a 

 trace milky — a kind of duck-egg blue, as if a few drops of milk had been 

 mixed with each gallon of sea water. Fishermen call this 'white water' and 

 consider it a good omen for herring fishing (p. 133). We do not yet 

 know enough about this group, and it may be that some we call separate 

 species are phases in the life history of the same organism, or even phases 

 in the life of something quite different.
