You have taken an introductory course in animal biology and know that animals have evolved with different types of symmetry.

Just by looking at the animal, what is a quick way that you can surmise the animal's mode of locomotion and method of food acquisition?
A)You need to put it back into the water and observe it.
B)Bilaterally symmetrical animals will show directed movement while radially symmetrical animals tend to be sedentary.
C)Bilaterally symmetrical animals will likely capture prey, while radially symmetrical animals will likely be filter feeders.
D)Bilaterally symmetrical animals will likely feed as they move fast, while radially symmetrical animals will likely move slower and feed on injured or dead prey.

Bilaterally symmetrical animals have a distinct anterior and posterior end, which allows for directed movement. They also have a mouth and anus, which allows them to capture prey and digest it. Radially symmetrical animals, on the other hand, do not have a distinct anterior and posterior end, and they typically feed by filtering food from the water.
