Spiders, along with all arachnids as well as any insect are invertebrates. They do not require a backbone for the fact that they are simple and small in physical structure. Any animal with a backbone is usually larger in size, and all mammals are vertebrates.
No, Spiders are invertebrates.
They're not. Insects have 6 legs, spiders have 8.
No, spiders do not have backbones. They belong to a group of animals called arachnids, which have an external skeletal structure called an exoskeleton for support and protection instead of an internal backbone.
Other animals that do not have a backbone include arthropods (such as insects and spiders), mollusks (such as octopuses and snails), and cnidarians (such as jellyfish and coral). These animals have different types of support structures instead of a rigid backbone.
No, a frog is not an arthropod. Frogs are amphibians, while arthropods are a group of invertebrates that includes insects, spiders, and crustaceans. Frogs have a backbone and belong to the class Amphibia.
No, Spiders are invertebrates.
if youre into spiders, bugs or snails they have no backbone
They have both a backbone and cartilage. Cartilage is found between the vertebrae. What your teacher probably intended to ask was if the squirrel has a backbone or a notochord. To that, you may answer yes, too. Embryonic squirrels have no bones. If you plan to answer "yes" you need to be prepared to defend your answer.
Invertebrate simply means no spine or backbone. Spiders do not have spines, therefore are invertebrates.
spiders and land insects
All spiders do not have backbones.
No. Nor do any Spiders have a backbone. Spiders' structural support comes from their hard external body panels. They do not have any bones.
No. Spiders are arachnids, which are invertebrates. Instead of bones, spiders have hard exoskeletons made of chitin.
Yes, spiders are invertebrates. They belong to the class Arachnida, which is a group of arthropods that includes spiders, scorpions, ticks, and mites. Invertebrates do not have a backbone or internal skeleton made of bone.
They're not. Insects have 6 legs, spiders have 8.
Sponges... Starfish.... Also things like worms too. Spiders...however, spiders are arachnids. But still they are invertebrates. (Invertebrates are animals/insects which have no cranium and backbone.) - emz
Animals are divided into two groups, vertebrates and invertebrates. Vertebrates are animals with a backbone and invertebrates are animals without a backbone. In the invertebrates group there are mollusks, Insects, crustaceans and arachnids. Spiders are part of the arachnid group along with scorpions.
