Do protists have tube feet?
No, tube feet are a characteristic feature of echinoderms, such as sea stars and sea urchins. Protists do not possess tube feet.
How do starfish stay on the rocks?
The starfish takes in water into the tube feet, (expanding the tube feet) the water is then forced out of the tube feet, (contracting the tube feet) making it able to grab onto the object.
What are tube feet on a star fish?
Tube feet are a series of small tubular projections that can be find on all echinoderms, including the star fish. By pumping fluids in and out of these tubes, hydraulic pressure is created that can be used to grip onto a surface or circulate materials around the feet. In star fish, tube feet are often used as suction cups to keep a grip on the environment and prevent being swept away by undersea tides.
What is the Niche of an astropecten?
The niche of an Astropecten, a type of sea star, is typically as a predator in marine environments. They feed on bivalve mollusks and other small invertebrates using their tube feet to slowly crawl and capture prey. Astropectens are important in maintaining the balance of ecosystems by controlling the population of these prey species.
Will a sea star be able to eat clams without using its tube feet. Explain?
No, sea stars use their tube feet to pry open the clam's shell and then evert their stomach into the clam to digest its soft tissues. Without the use of tube feet, the sea star would not be able to access the clam's flesh to consume it.
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 mollusks have adaptation for there feet?
yes
What is the locomotion of the Molluks?
muscular feet is the locomotory organ in mollusks
How do the tube feet of a starfish pull open the shells of mollusks?
they are called suckers on the ends of the tube feet. they are controlled by the water-vascular system in echinoderms, such as starfish.
Do protists have tube feet?
No, tube feet are a characteristic feature of echinoderms, such as sea stars and sea urchins. Protists do not possess tube feet.
What are tube functions of the tube feet?
One of the functions for tube feet are for movment, and also so they can pry open their clams.
What are the function of the tube feet?
Tube feet are structures that operate like a suction cup.
How do mollusks move place to place?
Use there feet to crawl walk or dig.
What structures of defense do mollusks have?
Defensive strategies employed include the presence of spines, toxins, which can be inherent or delivered through the tube feet, and the discharge of sticky entangling threads by sea cucumbers. Being stabbed by a sea urchin may result in painful injury.
The methods a starfish uses to obtain its food?
Most starfish eat mollusks, principally bivalves which they force open by seizing both halves of the shell with their tube feet and pulling the halves apart very slowly until the bivalve is exhausted.
What are the simple tube-shaped organs through which mollusks eliminate nitrogen-containing wastes called?
Its going to be a.gills
How do echinoderms use their tube feet?
Echinoderms use their tube feet by using their water vascular system, so their tube feet are basically controlled by a water pressure system. Tube feet are adapted to a different uses in the groups of echinoderms by being able to use their tube feet to attach to objects as well as for protection and the gaining their nutrients.
