Benthos 



Phytobenthos. The qualitative variety of the White Sea flora is only slightly 

 less than that of the Murman Peninsula. According to the data of E. S. Zinova 

 (1928), A. D. Zinova (1950), K. I. Meyer (1933), and A. Kalugina (1958) the 

 composition of the bottom algae in the White Sea is as set out in Table 83. 

 The flowering plants Zostera marina and Z. nana, the most interesting 

 warm-living relicts in the White Sea, have a very great importance for life in 

 this Sea. Zostera attains a specially large size in the White Sea (up to 2\ m), 

 and on the other hand forms, as in the North Sea, a littoral dwarf variety
