no they have no exo or inner skeleton
No, but they do have a shell, which acts like an exoskeleton; protecting them from predators, providing camouflage, and sealing in moisture.
No, many invertebrates do not have exoskeletons. For instance, the octopus (a shell-less mollusc) is an invertebrate but has no exoskeleton - it uses it flexibility to move into deep crevaces looking for prey to eat. There are also earthworms (annelids or segmented worms) that are invertebrates but have no exoskeletons. An exoskeleton is a rather specialized organ most commonly associated with insects.
animalChitin is a polysaccharide that strengthens the structure of arthropod (insect, crustacean, etc.) exoskeletons, as well as cephalopod (squid and octopus) beaks, and fungal cell walls.
no, they are mammals no mammals have exoskeletons
Yes, all insects have exoskeletons.
No, the don't. For example, crabs have exoskeletons.
Insects have exoskeletons for both protection and structural support.
No, insects have exoskeletons, which are hard, external skeletons that provide support and protection. These exoskeletons are made of a material called chitin.
No.
Yes, coral does have exoskeletons made of calcium carbonate. These exoskeletons provide structure and support for the coral polyps, which are tiny organisms that secrete the calcium carbonate to build the coral reefs. Over time, these exoskeletons accumulate and form the large coral reef structures we see in the ocean.
Yes, they do have exoskeletons. Exoskeletons are hard outer shells that protect and support the body.
"Exo" means external or outer in the word exoskeletons. Exoskeletons are rigid external coverings found in certain animal species that provide support and protection.
