Is a starfish an exoskeleton?
no a sea star is not a crustation
How is the armor of a grasshopper different from that of a starfish?
The armor of a grasshopper is an exoskeleton made of chitin, providing protection and support to its body. In contrast, a starfish does not have an exoskeleton but instead has a hard calcium carbonate skeleton underneath its skin, known as ossicles, for structural support.
Do starfish have scales?
No, starfish do not have scales. They have a hard, calcareous exoskeleton composed of tiny plates called ossicles. These ossicles provide structure and protection to the starfish's body.
Do starfish have back bone?
No, starfish do not have a backbone. They belong to a group of animals known as echinoderms, which have a hard, calcareous exoskeleton made up of plates called ossicles. This exoskeleton provides structure and support, but it is not a true backbone like vertebrates have.
What is a special characteristic of a star fish?
the special characteristic of starfish are they have an Exoskeleton and Radial symmetry
Does a starfish have feathers?
A starfish has neither fur or hair. It is an exoskeleton animal, which has its skeleton outside its body.
What hard substance is a starfishe's exoskeleton made of?
Starfish actually have ENDOskeletons, not exoskeletons. They are made up of calcium carbonate compounds called ossicles.
Do starfish shrink in size?
No. There is no hard, inflexible exoskeleton. The starfish skin has hard protuberances called ossicles, in the form of small plates and spines, which offers most species some protection. The only way a starfish can become smaller is through extreme starvation, disease, or losing one or more arms to a predator. In many starfish, the arms will regrow.
What type of skeleton do starfish have?
For a body plan, a starfish has 5-part radial symmetry, spiny skin, internal skeleton, water vascular system, and suction cup-like structures called tube feet.
Is a sea star a vertebrate?
A sea star has an exoskeleton, not a back bone. Which makes it an invertebrate.
What are starfish made up of?
Starfish are composed primarily of water and have a network of vessels that circulate seawater throughout their bodies. They also have a hard calcium carbonate exoskeleton that provides structure and protection. Additionally, they have a unique water vascular system that helps them move and feed.
Do fireflies have an exoskeleton or no exoskeleton?
