the tube feet of an echinoderm helps the animal, by making it move!. hope this helped.
Does an echinoderm have tube feet?
Yes echinoderms have that internal hydrological system that lets them run their tube feet.
What is an ambulacrum?
An ambulacrum is a row of pores of an echinoderm for the protrusion of appendages such as tube feet.
What are two ways you could identify an animal as an echinoderm?
Two ways you could identify an animal as an echinoderm would include five part radial symmetry and tube feet. Most of the animals also have skin that is spiny.
What is the organ for breathing of echinoderms?
On the ventral side of an echinoderm (say, a sea star, for example) there are hundreds of tiny feet arranged into rows on each appendage. These are called tube feet. By varying the internal water pressure, the echinoderm can extend and contract its tube feet for locomotion, food collection, and respiration
How does a echinoderm use its tube feet?
These tube feet have suction disks that enable the animals to crawl or attach themselves to objects. Think of a starfish "clinging" to the walls of the inside of a fish tank
What is an ambulacral?
An ambulacral is another word for an ambulacrum, a row of pores of an echinoderm for the protrusion of appendages such as tube feet.
What do echinoderms use for movement?
Echinoderms, such as seastars and sea urchins, use their tube feet to move. Tube feet have suction discs which allows the echinoderm to crawl or stick to various surfaces.
A vertebrates animals that has tube feet spines and arms that extend out from the body?
No, vertebrates are animals that have spinal columns. You are describing an echinoderm, which is an invertebrate.
What are the bulb-like sacs in echinoderms that push water through canals as a part of their vascular system?
The structure in an echinoderm that is a bulb like sac and pushes what is called the ampulla. It is connected to the radial canal of the water-vascular system. Each ampulla controls tube feet. The tube feet can extend when water pressure is increased by the ampulla being squeezed. :)
What is definition of starfish?
A marine echinoderm with five or more radiating arms. The undersides of the arms bear tube feet for locomotion and, in predatory species, for opening the shells of mollusks.
Do spiders have a firm body with internal support covered with scales or spiny plates tiny hollow tube feet for movement?
No it does not, you are describing a member of the echinoderm family.
