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.
Because Invertabrates 'means without a spine', so they don't need a spine!
No, Spiders are invertebrates.
Spiders need to live is water, food, and air.
No, spiders as well as other arachnids (like scorpions) and insects have exoskeletons. That means their bodies have hard outer shells, not internal bones.
Yes, but there is no need.
denotation or conotation? denotation. spiders don't have any bones @ all. conotation. if you had ever been in a fight w/ my little girl, you would already know that she won't back down from anything -- figuratively @ least.
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.
All spiders do not have backbones.
spiders and land insects
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.
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.
No, it only has an exoskeleton, like all arachnids.
Any animal that does not have a backbone, which includes worms, insects, spiders, jellyfish etc.
