What is a sea lilies and feather stars?
well you see my good chum
a feather star is located in the middle of the Arabian desert while the "sea lilly" being derived from the british botonist CPHAT yeaman , is a derogatory name for the common house cat.
Yes they are cold-blooded. I passed by a link searching also and I answered cuz I just found out. Hope I help!
The transition of a bilateral echinoderm larva into a radially symmetrical adult is an example of?
Anenome.
What are the four major groups of echinoderms?
There are actually four major classes of echinoderms. These are Crinoidea, Asteroidea, Ophiuroidea, Eichionidea, Holothuroidea, and Concentricyloidea. The animals in these range from sea lilies to sea urchins.
What size do sunflower starfish grow to?
Sunflower starfish can grow quite large, reaching a diameter of up to 3 feet (about 90 centimeters) or more. They typically have between 15 to 25 arms, which contribute to their expansive size. These starfish are known for their distinctive appearance and can weigh over 5 pounds (around 2.3 kilograms).
An echinoderm is a spiny-skinned organism like a starfish. Leeches are soft bodied organisms, so they can't be echinoderms.
What are the main characteristics of echinoderms?
I think you're reading out of a low-level-zoology book, there's actually 14 characteristics. But some of them are really hard to understand, i cant even understand some of them myshelf, but for some that i can understand, I'll type it in
1. Body unsegmented, radial
2.No head, no brain
3.It has a water-vascular system
4.Excretory organs abset( it cant pee)
5.And they can regenerate lost parts.
The other 9 are really hard to understand, i think you wouldn't really understand them
Echinoderms are a phylum with usually 5 fold symmetry, spines and calcium carbonate plates.
all echinoderms live in salt water like in oceans and seas. They are in every ocean. Most adult echinoderms live on the ocean floor in salt water feeding on different sea animals. Many echinoderms can be found in tide pools along beaches or in oceans. the tide pools can support a variety of echinoderms and is changed every time the tide goes out.
There are sea stars under the ice in the Antarctic and up in the north, Bering sea and around parts of northern Europe. Many are meat eating predators while some are grazers of algae.
How much wood can a woodchuck chuck if a woodchuck would chouldk wod?
a woodchuck could chuck as much wood as a woodchuck could if a woodchuck could chuck wood.
What are the five echinoderm classes?
The 5 living classes of echinoderms are Asteroidea (sea stars) Crinoidea (sea lillies) Echinoidea (sea urchins and sand dollars) Holothuroidea (sea cucumbers) Ophiuroidea (brittle stars and basket stars)
How are echinoderms radial symmetry different from a jellyfish?
ctenophorains(jellysfish) are spherical in shape much like a ball hence show radial symmetry. echinoderms(starfish) generally are flatter and have 5 arms hence are called pentaradial symmetry (can be cut in only 5 directions)
Do starfish live in cold water or hot water?
Some jellyfish prefer the cold waters. While other types of jellyfish love the warm waters. The jellyfish prefer to live in groups together. The can live in oceans and also freshwater.
How do echinoderms move and get their food?
For the sea star, they grap a clam with all five arms, then it pulls on the tightly closed shell with its tube feet. When the shell opens, the sea star forces its stomach out through its mouth and into the opening between the clam's shells. And then the digestive chemicals break down the clam's tissues, and the star sucks in the partially digested body of its prey.

No. Sponges belong to the phylum Porifera, which means 'pore bearing.' The have pores that are called incurrent vents, where water comes in, and excurrent vents, where water goes out. They are considered the most primitive of animals because they don't have any complex organs or tissues, so, for example, they don't have a circulatory system or a digestive system or a nervous system. Their cells are somewhat loosely structured in that some cells can move around from place to place in the sponge and there are some unspecialized cells that can become other kinds of cells. Also, they only have two layers of cells. There are some types of sponges that you can put through a sieve to separate all the cells but then the cells will go back together to recreate a sponge again.
Echinoderms are a completely different and more advanced phylum. They have organ systems and fixed (non-changing) cell types and more layers of cells. Also, if you put an echinoderm through a sieve, he's a gonner.
Explain how echinoderms use the water-vascular system?
Here is an example in sea stars. Water enters into the body of the sea star though a plate on the top. The water rushes through the body and down each of it's tentacles. The moving water fuels the hydraulic system of its tube feet. Because of the water entering it's body, its muscles can move its feet and allow movement for the whole sea star. The same is true with most echinoderms.
What are facts about echinoderms?
Echinoderms are made up of starfish, sea cucumbers, brittle stars, sea urchins, etc.
Echinoderms are organisms in the phylum Echinodermata, which is Latin for "spiny-skinned."
Echinoderms have radial symmetry, which means that you can divide them into sections with a central point like spokes on a wheel (ex. divide them into eight equal sections), and each section would be the same. To better understand this, see the question "What is radial symmetry?"
Echinoderms live in the ocean.
Echinoderms don't have hearts or brains.
Echinoderms have tube feet, which are similar to suction cups. The tube feet stick on to surfaces or prey.
This answer is more relevant than the previous one, which stated "I'll put the answer later. Here's an interesting poem: Fleas

What is it called when a starfish loses arms and regrows them?
The general process is called regeneration. Some species of starfish reproduce by fission using regeneration to make each half into a full and separate organism.
Echinoderms, such as starfish, have basal nerve ganglia that serve as a nervous system. They also have a water vascular system that acts as a circulatory system. They can reproduce, move, and digest food. Therefore, they are animals.
What factors influence how fast echinoderms grow and how big they become?
The health of the echinoderm influences growth speed.
