Platyhelminthes exhibit bilateral symmetry, meaning they can be divided into two equal halves along a single plane. This symmetry type allows for better movement and coordination in these flatworms.
Most animals in the Mollusk phylum have bilateral symmetry, where their body can be divided into two equal halves along a single plane. This symmetry allows for more efficient movement and sensory abilities.
Symmetry in animals of the phylum is typically categorized as radial or bilateral. Radial symmetry is when an organism can be divided into equal halves in multiple planes around a central axis, like a sea anemone. Bilateral symmetry is when an organism can be divided into two equal halves along just one plane, like a human.
Not closely: spiders are arachnids (a type of chelicerat), octopuses are cephalopods (a type of mollusk). However it is believed that all living things do have an ultimate common ancestor, no matter how much they have diverged from each other.
Adult Hemichordates exhibit bilateral symmetry, meaning their bodies can be divided into two similar halves along a single plane. However, during their larval stage, some species of Hemichordates show a form of metameric or radial symmetry.
One type of symmetry is rotation. The second type of symmetry is translation. The third type of symmetry is reflection.
All species of spiders are arthropods, and arthropods 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.
Tarantulas are spiders; spiders are arthropods, and all arthropods 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.
