Opsanus sp. is likely an undescribed offshore form. 



and three major habitat types (two-way ANOVA, 

 P<0.05, no significant survey x habitat interaction). 

 Numbers of species and overall densities were great- 

 est on ledge habitats, intermediate on live-bottom, 

 and smallest over sand (Figs. 3 and 4, Table 2). Num- 

 bers of species and densities were highest during the 



summer of 1985, intermediate during the fall of 1985 

 and summer of 1986, and lowest during the spring 

 of 1986 (Table 2). The lower number of species ob- 

 served in spring of 1986 may be a result of fewer 

 samples having been taken because of inclement 

 weather. Underwater visibility varied from 2.4 to 17.9
