Invertebrates do not have a spine (backbone) like vertebrates do. Fish, Birds, Reptiles, Amphibians, Mammals are vertebrates with internal skeletons, spines, heads, and brains with central nervous systems. All insects are invertebrates and they mostly have exoskeletons (external skeletons), and no backbones. Their internal organs make up the entire contents of their interior structures.
There are many animals which are invertebrates. Instead of skeletons they have other means of support; such as hard outer shells or fluid filled hydrostatic skeletons.
Invertebrates have a hard outer shell or fluid-filled, hydrostatic skeletons.
They have an external skeleton, which is made from a fibrise material known as chitin
An exoskeleton, a hard armour on the outside to keep the soft stuff in.
invertebrates dont have backbones
No. Spiders are arachnids, which are invertebrates. Instead of bones, spiders have hard exoskeletons made of chitin.
slug, snail, skark (they have tissue instead of bones),
No insect has a backbone - they are all invertebrates with an external skeleton instead of an internal one.
No, they have bones.
no, they are invertebrates
just bones actually..vertebrates have bones and invertebrates got none..
Arachnids have no bones. They're invertebrates.
you can put them in any groups, but the 2 main groups you are looking for are called = invertebrates and invertebrates (vertebrates have bones and invertebrates don't have any bones)
Slimy creatures - - - - Invertebrates
they do not have back bones
No, invertebrates don't have back bones but goats have so they are vertebrates
Yes, as a vertebra is a piece of a backbone. As such invertebrate means an organism that does not have a spinal column or back bone. Crabs have an exoskeleton (their external shell serves as a skeleton) instead of a back bone, they are therefore considered invertebrates. Crabs have no bones, including no vertebrae (backbones). They are invertebrates.
