Fig. 6. Relationships between (A) ram and (B) suction distance and mouth diameter (gape at t_capture) when feeding on guppies. Values are means for each species in the study. The regression between ram distance (r²=0.72, P=0.016) and gape distance is significant, but that between suction distance and gape distance is not (r²=0.06, P=0.65). Species are as follows: ( ${triangleup}$ ) Petenia splendida; ( ${circ}$ ) Cichla ocellaris; ( ${square}$ ) Astronotus ocellatus; ( ${triangleright}$ ) Crenicichla geayi; ( ${triangleleft}$ ) Cichlasoma minckleyi; ( ${triangledown}$ ) Heros severus; (e) Cyprichromis leptosoma.
