What are ambulacral ossicles?
In a starfish, the ambulacral ossicles are little calcified bony plates covering the radial canal.
What is the function of the ambulacral groove?
The function of the ambulacral groove on a starfish is to open the shells of bivalves. It also hold the tubed feet of the starfish.
On what surface is the Ambulcaral groove visible on a star fish?
Echinoderms can have ambulacral parts that include ossicles, plates, spines, and suckers. For example, sea stars or "star fish" have an ambulacral groove on their oral side (underside). This ambulacral groove extends from the mouth to the end of each ray or arm. Each groove of each arm in turn has four rows of hollow tube feet that can be extended or withdrawn. Opposite the ambulacral groove is an ambulacral ridge on the aboral side of each ray.
What is the main function of the ambulacral system in ehinoderm?
locomotion
Is a trench that runs along the ventral surface of the starfish's arms and holds the tube feet?
The Ambulacral Groove
What are the deep furrows extending from the mouth to the tips of each arm on a star fish called?
open ambulacral grooves
What is the ambulacral ridge of a starfish?
It is the part that extends from the ring canal, all the way to the tip of the starfish. It's under the gonad.
What is a groove of a starfish?
If your asking where it is, its on the Ventral(bottom) side. It is the indent in the starfishes' skin that goes through all of the starfishes' rays (arms). It is called the ambulacral groove.
What is the same about all echinoderms?
They belong to the phylum: Marine animals. Have radial symmetry, a mesodermal skeleton and they all have a water vascular system called: ambulacral.
What is the function of the spines in a sea star?
The spines on the oral surface are softer and bend to cover the mouth of the starfish as well as the ambulacral grooves. They are basically for protection.
How an echinoderm ciculates oxegyn?
echinoderms circulate oxygen using a unique system. Rather than having blood, they circulate water that they use for exchanging carbon dioxide for oxygen. It is comprised of a central ring in the main body, and then tubes that radiate out into the appendages. You can learn more about this system, called the ambulacral system, by going to the related link.
System that allows echinoderms to move eat and breathe?
Echinoderms do not have a respiratory system similar to a person's. Instead, they have a water vascular (otherwise known as "ambulacral") system, made up of a network of canals to move water. This method accounts for the creature's gas exchange, feeding, and locomotion. Because of this characteristic, echinoderms lack gill slits.
