Some lizards are active foragers; they spend most of their day roaming the ground in search of prey. How do the leg muscles of a sit-and-wait predator (like a frog) differ from the leg muscles of an active forager (like a lizard)? (a) Describe how the two differ with respect to muscle fiber types, fatigability, and density of mitochondria, myoglobin, and capillaries. (b) Relate these structural differences to functional differences in the animals' respective foraging strategies.

Explanation / Answer

Leg muscles are used for locomotion in predators and catching their prey

Sit and wait predators like frogs have spring tendons in the muscle, due to whicn the tendons can stretch and help the frog to catch the pray
