The joints in the exoskeleton, evident in the appendages and body segmentation, are essential because of the physical rigidity of the exoskeleton's makeup. It is constructed of a tough protein, chitin (similar in function to hair and fingernails, claws, beaks, and so forth) and typically further hardened with biomineralization. Because of its limited flexibility, a strategy would have to be employed to provide limb and body flexion, for example, to facilitate locomotion; walking, swimming, flight. Without limb jointing, the organism would be immobile.
What else can I help you with?
Do prawns have endoskeletons?
No they do not. They have exoskeletons and thus are invertebrates.
Does a shrimp have a backbone?
NO. Shrimp and other crustaceans have exoskeletons, and they are invertebrates.
Why do invertebrates have to molt but vertebrates do not?
vertebrates dont molt because as they grow their bones grow unlike the bones of invertebrates the exoskeletons of invertebrates cant grow so the animal sheds of the old exoskeletons and makes a new one and that is called molding
Do a spider have backbone?
No. Spiders are arachnids, which are invertebrates. Instead of bones, spiders have hard exoskeletons made of chitin.
Are insects vertebrates?
No, insects are invertebrates because they contain exoskeletons, not endoskeletons. no they are invertebrates
Is a monarch butterfly a invertebrates?
All butterflies are invertebrates. They have exoskeletons, meaning that their physical support structure is on the outside of their bodies instead of on the inside.
Do invertebrates without bones have something rigid for their muscles to pull against?
Many invertebrates have shells or exoskeletons which can be used to anchor muscles.
What does an invertebrate protect or do?
An invertebrate is a classification of an animal which means that the animal does not have a spine. A good example of an invertebrate is a jellyfish. There are also some insects that are invertebrates, amny of which have exoskeletons, or a hard outer shell to protect them.
Are exoskeletons considered vertebrates?
No because creatures with exo-skeletons do not have a vertebrae. So they are invertebrates. :)
Are echinoderms mammals?
No. Mammals belong to the vertebrates group and echinoderms are invertebrates, and have exoskeletons instead.
Is a butter fly an vertebrate or an invertebrates?
All butterflies are invertebrates. They have exoskeletons, meaning that their physical support structure is on the outside of their bodies instead of on the inside.
Are jellyfish mammals?
No. Mammals have a spine, and produce milk for their young, and have at least SOME body hair. Jellyfish do not have these characteristics.
