Animals having identical right and left sides are also known as:

Bilaterally symmetrical

Detailed

Bilateral symmetry is a type of symmetry where an organism can be divided into two equal halves along a single plane. In animals with bilateral symmetry, the right and left sides of their bodies are mirror images of each other. Here is a detailed explanation:


  • Bilateral symmetry: Bilateral symmetry is a common characteristic found in many animal species.

  • Dividing plane: The dividing plane that separates the organism into two equal halves is called the sagittal plane.

  • Mirror images: The right and left sides of an organism with bilateral symmetry are mirror images of each other.

  • Examples: Many familiar animals, such as humans, dogs, cats, and birds, exhibit bilateral symmetry.

  • Advantages: Bilateral symmetry allows for efficient movement and specialization of body parts.

  • Evolutionary adaptation: Bilateral symmetry is believed to have evolved as an adaptation for better coordination and mobility.

  • Contrast with other symmetries: Bilateral symmetry is different from radial symmetry, where an organism can be divided into multiple equal parts around a central axis.


Therefore, the correct answer is B: Bilaterally symmetrical.
