 in the surrounding milieu" {op. cit., p. 486). 



The observed relationships between infauna and water circulation may also 

 be explained by the extinction or reduced growth of adult individuals by un- 

 favorable water circulation acting directly through water properties, such as 

 temperature, salinity, food substances, etc., or indirectly through the presence 

 of predators or unfavorable bottom types {op. cit., p. 471).
