How do the tube feet of an echinoderm help the animals?
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 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 are two ways you could identify an animal as an echinoderm?
You could identify an animal as an echinoderm by looking for characteristics such as a spiny skin or radial symmetry. Another way is by checking if the animal has a water vascular system, which is unique to echinoderms and helps with movement and feeding.
The water vascular system of an echinoderm regulates?
Locomotion. In the sea star, water enters the system through a sieve plate. Eventually it is pumped into many tube feet, expanding them. When the foot touches a surface, the center withdraws, producing suction that causes the foot to adhere to the surface. By alternating the expansion and contraction of it's many tube feet, a sea star moves slowly along.
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.
