Spiders have bilateral symmetry. That is, its left and right side are more or less mirror images.
Bilateral
Phylum Porifera sponges have radial symmetry.
The mollusk phylum contains animals that have the body symmetry similar to snails. This includes animals that have soft bodies and have shells.
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.
No Coelom Bilateral Symmetry as larva, radial as Adult. Many consider to be bilateral.
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.
