Morphology Changes with Different Prey

Caption

Bigmouth sleepers that feed on other fish have more elongate bodies, with their greatest body depth shifted toward their tail to provide quicker acceleration. They have larger mouths that open wide to more effectively suck in evading fish prey. Sleepers living without other fish eat invertebrates. They have deeper heads with a smaller mouth that allows them to produce a narrower but much more powerful suction to capture small prey.
