Comparison of scaling of suction morphology, kinematics and buccal pressure to standard length (or cranial length) based on published reports in five fish species

Species	Morphology	Strike duration	Pressure
Largemouth bass	Decreasing lever arm ratio of lower jaw with size^¹	Increasing with size^¹	No significant trend^²
Bluegill sunfish	Decreasing lever arm ratio of lower jaw with size^³	Increasing with size^³	Decreasing with size^²
Spotted sunfish	Decreasing lever arm ratio of lower jaw with size^³	Increasing with size^³	No significant trend^²^,^⁴
African catfish	Isometric growth of lever arm ratio of lower jaw and positive allometry of muscle cross-section with size^⁵	Increasing with size^⁶	Mean pressure decreasing with size (marginally significant)^⁷
Snook	Isometric growth of sternohyoideus muscle and buccal cavity area^⁸		No significant trend^⁸
