The answer is very simple. an octopus of course It has no antannae but do own an exoskeleton,
insects must have an outer skeleton, six legs, three parts to their body, have bilateral symmetry, and antennae.
Insects have three body parts - head, thorax and abdomen. 15 Three. twelve. By VA
An ant has one pair of antennae on its head which it uses for sensing chemicals in its environment, but they do not have noses as we do. Instead, ants have special odor receptors located on their antennae and other parts of their body to help them detect smells from the world around them.
Did you mean Appendages? If so, An appendage is an external body part, or natural prolongation, that protrudes from an organism's body, such as a vertebrate's limbs. In invertebrate biology, "appendage" is a general term that covers any of the homologous body parts that may extend from a body segment. These include antennae, mouthparts (including mandibles, maxillae and maxillipeds), wings, elytra, gills, walking legs (pereiopods), swimming legs (pleopods), sexual organs (gonopods), and parts of the tail (uropods). Typically, each body segment carries one pair of appendages. Appendages may be uniramous, as in insects and centipedes, where each appendage comprises a single series of segments, or it may be biramous, as in many crustaceans, where each appendage branches into two sections. Triramous (branching into three) appendages are also possible. All arthropod appendages are variations of the same basic structure (homologous), and which structure is produced is controlled by "homeobox" genes. Changes to these genes have allowed scientists to produce animals (chiefly Drosophila melanogaster) with modified appendages, such as legs instead of antennae.
First of all an insect has six legs and a spider has eight legs. Spiders belong to a group of animals called Arachnids. Ticks, mites, and scorpions belong to this group too. (They also have eight legs.) If you want to learn more, please visit www.Brainpop.com Insects have an exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. An Insect has three main body parts and six legs. A Spiders has eight legs and 2 main body parts.
That'd be an arachnid, most likely a spider. Spiders have a cephalothorax ('head chest', exactly what it sounds like) and an abdomen (butt, containing vital organs), and four pairs of walking legs.
Butterflies and wasps are not crustaceans, they are insects. They have a pair of antennae, 3 body parts and 6 legs unlike crustaceans that have 2 pairs of antennae, varied number of legs and body segments.
chelicerata have got 5 pairs of legs whereas crustaceans have 6 pairs.chelicerata have 2 pairs of antenae whereas crustaceans doesnt have antenae.chelicerates have uniramous appendages,crustaceans have biramous appendages.
They are related because they all perform some part in the crayfish. Without those parts the crayfish will not survive.They are not related at all!!
mandible
The 8 parts of the appendages are: The antennae, mouthparts (including mandibles, maxillae and maxillipeds), wings, elytra, gills, walking legs (pereiopods), swimming legs (pleopods), sexual organs (gonopods), and parts of the tail (uropods). (I hope that helped!)
A spider! Spiders have 4 pairs of legs (8 total), and a body divided into two segments.Further information: A spider belongs to the group, arthropod. An arthropod is an invertebrate animal having an exoskeleton (external skeleton), a segmented body, and jointed appendages.
Insects have six legs, three body parts, and antennae, while spiders have eight legs, two body parts, and no antennae.
antennae wings and body
They do. Tagmosis is the specialization of parts, and crayfish have many appendages specialized for certain uses. The claws they have are specialized for grabbing food, cutting, and defending itself. There are small appendages around the mouth that are used to hold food while chewing. The four pairs of walking legs are used for walking as well as probing the surface they are walking on for food. In males, the copulatory swimmerets are specialized appendages used in reproduction. Their antennae are also specialized for sensing the world around them. The other swimmerets and the uropods are also specialized.
Trilobite
Insects have six legs and three main body parts (head, thorax, and abdomen), while spiders have eight legs and two body parts (cephalothorax and abdomen). Additionally, insects typically have wings and antennae, which spiders do not have.
