Does a starfish have an exoskeleton?
Sea Stars otherwise known as Star Fish are Echinoderms and they do not have an exoskeleton, they have an endoskeleton.
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.
What type skeleton does a sea star have?
endoskeleton i believe
What is the structure and function of an endo skeleton in echinoderms?
Echinoderms possess a unique endoskeleton composed primarily of calcareous plates or ossicles, which are embedded within their mesodermal tissue. This endoskeleton provides structural support and protection while allowing for flexibility and movement, particularly through the use of tube feet. The ossicles can vary in size and shape, contributing to the diverse forms of echinoderms such as sea stars, sea urchins, and sea cucumbers. Additionally, the endoskeleton plays a role in locomotion and defense against predators.
What kind of echinoderms have shell-like endoskeleton?
Sea Cucumbers.
What animals are phylum echinodermata?

What is the scientific name of spiny skinned animals?
Echinoderm is the scientific name for spiny-skinned animals. Spiny-skinned animals include sea urchins, sand dollars, brittle stars, starfish, and sea cucumbers.
The phylum that includes starfish sea stars sea cucumbers and sea urchins?
The phylum that includes starfish (sea stars), sea cucumbers, and sea urchins is Echinodermata. This group is characterized by its radial symmetry, a water vascular system, and a calcareous endoskeleton. Echinoderms are primarily marine animals and play important roles in their ecosystems as predators, scavengers, and prey. They also exhibit unique regenerative abilities, allowing them to regrow lost body parts.
This echinoderm has an endoskeleton made of a single crystal of calcium carbonate?
The echinoderm with an endoskeleton made of a single crystal of calcium carbonate is a sea urchin. This endoskeleton is made up of many plates that fit together, forming a rigid structure that surrounds the sea urchin's soft tissues and protects it from predators.
What characteristics do sea starssea urchins and brittle stars have in common?
Sea stars, sea urchins, and brittle stars all belong to the phylum Echinodermata, which is characterized by their radial symmetry, a water vascular system, and a calcareous endoskeleton made up of ossicles. These marine animals also exhibit regeneration capabilities, allowing them to regrow lost limbs or parts. Additionally, they all possess tube feet, which aid in locomotion and feeding, and they are primarily found in ocean habitats, often on the seafloor.
What phylum contains sea stars?
Includes: Sea Stars, Sea Lillies, Sea Urchins, Sea Cucumbers, Brittle Stars
Skeletal plates in starfish?
They make up the skeleton and protect internal structures.
