Yes echinoderms have that internal hydrological system that lets them run their tube feet.
the tube feet of an echinoderm helps the animal, by making it move!. hope this helped.
It helps it move from place to place! :)
An ambulacrum is a row of pores of an echinoderm for the protrusion of appendages such as tube feet.
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
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
An ambulacral is another word for an ambulacrum, a row of pores of an echinoderm for the protrusion of appendages such as tube feet.
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.
No, vertebrates are animals that have spinal columns. You are describing an echinoderm, which is an invertebrate.
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.
for attachment
To move around
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.
