Mobility and active predation and escape are best correlated with Bilateral Symmetry of Animal Kingdom
Explanation:
The animal exposing bilateral symmetry utilizes this specific feature in mobility, active predation and escape. Due to streamlined body arrangement they have the ability to live in any places which may be a hole or a small crack in between the rocks etc.
They also use this feature to exhibit a pace movement in water and other region in which they survive. Due to cephalization organism exhibiting bilateral symmetry has the ability to think and act spontaneously which helps them to escape from the predators.
