Fig. 7. Scaling of ram distance with fish standard length (SL). The relationship between ram distance and SL is not significant (r2=0.04, P=0.68). The relationship between suction distance and SL (not shown) was also not significant (r2=0.006; P=0.77). Species are as follows: (
) Petenia splendida; (
) Cichla ocellaris; (
) Astronotus ocellatus; (
) Crenicichla geayi; (
) Cichlasoma minckleyi; (
) Heros severus; (e) Cyprichromis leptosoma.
