Ipsilateral
Flatworms exhibit bilateral symmetry, which means that their body can be divided into two symmetrical halves along a single plane. This type of symmetry allows for the development of more complex body structures and directional movement.
Most animals have symmetrical body structures, with bilateral symmetry being the most common type where the body can be divided into two equal halves along a single plane. Other types of symmetry found in nature include radial symmetry (seen in organisms like jellyfish) and spherical symmetry (found in organisms like some single-celled algae).
Symmetry is used to classify animals based on their body structures and organization. Animals can be classified as having radial symmetry (body parts arranged around a central axis) or bilateral symmetry (having a left and right side that are mirror images). Symmetry helps scientists understand the evolutionary relationships between different animal groups.

Porcupines have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.

Yes, humans have bilateral symmetry, meaning their body can be divided into two mirror-image halves along a single plane. This symmetry is present in many animals and helps in organizing body structures systematically.

A butterfly exhibits bilateral symmetry, meaning its body can be divided into two mirror-image halves along a central axis. This type of symmetry is common in many animals and allows for balanced body structures that aid in movement and flight. Additionally, the patterns on a butterfly's wings often reflect this symmetry, enhancing their visual appeal.

How can you identify the body symmetry of an animal
Bilateral symmetry in crabs allows for a more streamlined body shape, which enhances their ability to move efficiently through their aquatic environment. This symmetry aids in balanced movement and coordination, enabling crabs to navigate complex habitats, escape predators, and hunt for food effectively. Additionally, having symmetrical body structures helps in the development of sensory organs, facilitating better perception of their surroundings. Overall, bilateral symmetry plays a crucial role in the crab's survival and adaptability.
