 California (Gilbert, MS. notes). 



Loving- the Avarm shallow water of the sand beaches, they may 

 be seen in small schools on bright sunny days in San Diego Bay, 

 so close to the shore that their backs appear above the water, and 

 the little Avaves frequently roll them high and dry on the sand, 

 from which they quickly struggle into the water again.
