Atlantic it has been reported between 120 (Lagar- 

 dere 1971) and 700 m (Maurin 1961). 



The temperature-depth relationship for P. ser- 

 rata is presented in Figure 38. In three areas, two 

 in the Gulf of Mexico and one in the southern part 

 of the Caribbean (off Venezuela), this shrimp 

 shows similar ranges of temperature and depth. In 

 the northeast Gulf, however, the range is appar- 



ently more extensive, the animals having pene- 

 trated shallower and warmer as well as deeper and 

 colder waters. According to the available data, the 

 population off the southeast coast of the United 

 States occurs within the shallower range depths 

 occupied by other populations, but at lower tem- 

 peratures. Actually, in that area the shrimp is not 

 restricted to the depths presented in the graph.
