Does arthropods have radial symmetry?
An arthropod’s body can be divided vertically into two mirror images. An arthropod shares this symmetry with many other animals such as fish, mice and even humans. Other animals such as the jellyfish and sea star exhibit radial symmetry, while coral and sea sponge are asymmetrical — exhibiting no pattern at all.

Do arachnids have bilateral symmetry?
Spiders and Insects. The phylum arthropoda includes insects (hexapoda), spiders (arachnids), crustaceans, and myriapods. These animals have bilateral symmetry, segmented body parts, hard exosketletons, jointed legs, many pairs of legs. These animals have two body parts, eight legs, and do not have wings or antennae.
Do insects have bilateral symmetry?
Most Insects have what is called Bilateral Symmetry. This means that if you had to draw a line through the middle of their bodies you will see that both sides are the same. It’s as if one side is a mirror image of the other one.
Are humans radial or bilateral?
The body plans of most animals, including humans, exhibit mirror symmetry, also called bilateral symmetry. They are symmetric about a plane running from head to tail (or toe). Bilateral symmetry is so prevalent in the animal kingdom that many scientists think that it can’t be a coincidence.
What is bilateral radial symmetry?
radial symmetry: a form of symmetry wherein identical parts are arranged in a circular fashion around a central axis. bilateral symmetry: having equal arrangement of parts (symmetry) about a vertical plane running from head to tail.
Where is radial symmetry found?
Radial symmetry is found in the cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars).
Does a sponge have radial symmetry?
Sponges are unsymmetrical or radially symmetrical, with many cell types but no distinct tissues; their bodies contain numerous pores and sharp protective spicules.
Is a beetle radial or bilateral?
Bilateral Symmetry This is demonstrated by the beetle in Figure above. With concentrated nerve tissue at the head but not at the tail end, the two ends of the body are distinct from each other.
What is a disadvantage of radial symmetry?
Radial symmetry may provide some advantages, but it seems to come with a number of disadvantages, too. A radially-symmetrical animal has no front and no back, no right and no left; such animals typically have their sense organs scattered around the body surface instead of concentrated in one region.
Why is a butterfly symmetrical?
They have a single line of symmetry down the middle of their body, meaning the patterns on their wings are the same on both sides. This makes them fascinating examples to explore symmetry – and have a bit of fun at the same time!
Are butterfly wings perfectly symmetrical?
Mirror images will perfectly fit together. When a butterfly folds its wings upward, they are perfect matches in size, shape as well as patterns. A symmetrical figure has one or more lines of symmetry.
Do butterflies have an exoskeleton?
Do butterflies have bones and muscles and skin like we do? A butterfly’s skeleton is not inside their body, but on the outside and is called the exoskeleton. Its like having skin made of bones.
What are butterfly wings?
Butterfly wings are made of two protein membranes that are covered in thousands of scales and tiny hairs. These wing scales are overlapping pieces of the protein chitin and are modified, plate-like setae. The colors and patterns of butterfly and moth wings come from these layers of tiny scales.
Are all butterflies female?
Size. Generally, female butterflies are larger than males. This is for reproductive purposes, as females need larger abdomens and wings in order to carry their eggs, which number in the hundreds per clutch. Small pupae, or caterpillars undergoing transformation to become butterflies, are typically female.
