Chitin forms the exoskeleton of arthropods (insects, crustaceans, etc.).
It's also found in the scales of certain types of fish (such as carp).
And it is found in the cell walls of fungi and the shells of mollusks.
Not really. Exoskeletons are chitinous and not subject to ossification because they are not bone but a dense form of protien.
Chitinous teeth in crayfish help them grasp and manipulate food as they feed. These teeth are used to crush and grind food items, making it easier for crayfish to consume their prey. Additionally, chitinous teeth aid in the breakdown of food particles during digestion.
Crustaceans such as Lobsters and Crabs have exoskeletons. Check out the "Yeti Crab" sometime when you have time: It was only discovered in March of 2005 and it does look strange.armadillo, lobsters, crayfish, scorpionInsects, spiders and crustaceans have exoskeletons.
Please help
It is a eukaryotic organism (aka, Fungus) that is a member of the kingdom Fungi, and is an heterotrophic organism possessing a chitinous cell wall.

Rattlesnakes do not have exoskeletons. Their skin may look chitinous but it is not an exoskeleton.
Spiders and crabs both have chitinous exoskeletons and many limbs.
Insects such as butterflies do not have skin, they have shells, technically chitinous exoskeletons, made of protein.
Spiders have chitinous exoskeletons, eight legs, multiple compound eyes, many of them create webs, and they are predatory.
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.
Hornets with their jointed limbs and chitinous exoskeletons are most definitely arthropods, under Arthropoda's subphylum Hexapoda, along with all other insects.
No, orca (killer whales) are cetaceans, or marine mammals; since they possess a backbone they are classified in phylum Chordata. Arthropods (phylum Arthropoda) differ in that they have chitinous exoskeletons (think of crabs, lobsters, millipedes, insects), have segmented bodies, and no backbone.
no, they are mammals no mammals have exoskeletons
Arthropods are a category of invertebrate characterized by chitinous exoskeletons and segmented bodies; the three types are insects, arachnids, and crustaceans. Bodies of arthropods typically come in three sections, the head, the thorax, and the abdomen. Each of these is a segment. But some species, such as a centipede or a millipede, have more segments.
Yes, all insects have exoskeletons.
No, the don't. For example, crabs have exoskeletons.
