How do echinoderms use their endoskeleton like an exoskeleton?
Echinoderms, such as sea stars and sea urchins, have an endoskeleton made of hard plates called ossicles that lie inside their bodies. Although this endoskeleton is internal, it functions similarly to an exoskeleton by providing support and protection. It allows echinoderms to control their body shape and movement, just like an exoskeleton does for other invertebrates.
Which animal have a exoskeleton and which animal have a endoskeleton?
Insects, arachnids, and crustaceans have an exoskeleton, which is a hard outer shell for protection and support. Vertebrates, such as mammals, birds, reptiles, amphibians, and fish, have an endoskeleton made up of bones and cartilage inside their bodies.
Why are ossicles classified as endoskeletons?
In echinoderms, such as starfish, an ossicle is a bony plate providing structure and protection. It is covered by an epidermis and considered part of the hard endoskeleton where the bony (calcite) plates (ossicles) are connected by collagen fibers.
Do all Crustacea have shells?
yes, bony fish have endoskeleton made of bone.
What protein makes up a sponge?
The flexible protein fibers that make up a sponge are called spongin. The hard, tiny spikes found in sponges are called spicules, and they are made of silica or calcium carbonate.
What is the hard endoskeleton found in echiniods is called a?
test
Do chipmunks have an exoskeleton or endoskeleton?
Chipmunks, like all mammals, have an endoskeleton, which means their bones are internal. An exoskeleton is a hard outer covering found in arthropods like insects and crustaceans. Chipmunks do not have an exoskeleton.
What is the opposite of an exo-skeleton?
The opposite of an exoskeleton (outer shell-like support structure eg insects, arachnids) is an endoskeleton (inner structure, such as mammals and reptiles have.)
Does rabbit has endoskeleton?
A endoskeleton is the internal skeleton of an animal. Since a cat's skeleton is on the inside of its body, it has a endoskeleton.
What are the 2 kinds of skeleton?
The two main types of skeletons are exoskeletons and endoskeletons. Exoskeletons are hard external skeletons found in insects and crustaceans, while endoskeletons are internal skeletons found in vertebrates like humans and fish.
Difference between exoskeleton and endoskeleton?
Just what the name says. Endo means inside and exo means outside. Our skeleton would be an example of an endoskeleton, whereas insects are a good example of organisms which have an exoskeleton.
What does every endoskeleton have?
Are made of hard material ( bones and cartilage ) that are inside the body.

What is the difference between the exoskeleton and the endoskeleton of a frog?
An exoskeleton refers to the jointed, hard, outer coverings of a soft bodied organism, such as the covering on an insect or spider. An endoskeleton is a hard internal structure that supports an organism. Frogs do not have any exoskeleton, but they do have an endoskeleton which supports their muscles and organs, protects their organs, and acts as a system of levers that muscles can pull on to allow the frog to move.
Does a zebra have a endoskeleton or a exoskeleton?
Birds, fish, mammals, reptiles and amphibians are all vertebrates. All vertebrates have and internal bone structure to support them (endoskeletons) The prefix "endo" means "inside" The prefix "exo" means "outside".
What is the difference between exoskeleton and endoskeleton?
Endoskeleton is the internal skeleton, which is what most people refer to when they just say skeleton. The exoskeleton, on the other hand, is an external skeleton which has protective features, eg crustaceans hard shell.
