How many noses does an ant have?
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.
What are appedages?
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.
Why is a spider not an insect?
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.
What is an arthropod with two body sections and four pairs of legs?
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.
Are butterflies and wasps crustaceans?
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.
What is the difference between crustaceans and chelicerata?
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.
How are the antennae other walking legs and swimmerets related?
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!!
What are the chewing mouth parts of arthropod called?
mandible
What are the 8 parts of the appendages?
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!)
If an animal with 8 legs and 2 body parts?
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.
What is the difference between insects and spiders?
Insects have six legs, three body parts, and antennae, while spiders have eight legs, two body parts, and no antennae.
What 3 parts does monarch butterfly has?
antennae wings and body
Do crayfish have tagmosis?
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.
An extinct arthropod with an oval body segmented in three parts?
Trilobite
The easiest way to tell whether an arthropod is an insect or a spider is to?
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.
