Length-frequency distribution of larval common dolphin (Coryphaena hippurus) and pompano dolphin (C. equiselis) 

 in the northern Gulf of Mexico by season. Catches are from both bongo and neuston net tows; seasons are com- 

 bined across years. Spring: March-May, Summer: June-August, Fall: September-November. Length categories are 

 combined by 2-mm intervals; >0.5-mm increments are rounded to the nearest whole number. N = number of larvae.
