What is water vascular system and its general structure and function?
The water vascular system is a hydraulic system used by echinoderms, such as starfish and sea urchins, for locomotion, food and waste transportation, and respiration.
What is a dorsal on a starfish?
The dorsal surface of a starfish refers to the top surface of its body, which is typically covered with spines or other protective structures. It is opposite to the ventral surface, which is the underside of the starfish that may have tube feet used for locomotion.
Do starfish have scales?
No, starfish do not have scales. They have a hard, calcareous exoskeleton composed of tiny plates called ossicles. These ossicles provide structure and protection to the starfish's body.
What are the bony plates of a starfish called?
where bony plates growth zone is found in..
What is the function of a bacterial fiagellum?
A flagellum is a hair like structure that protrudes from the body of a prokaryotic or eukaryotic organism. Its primary function is for locomotion.

What is the mode of locomotion of starfish?
Trains.
What is a long hair like structure used for locomotion?
flagellum

Where is the Suckers on a starfish?
Suckers on a starfish are located on the tube feet, which are part of its water vascular system. These tube feet extend from the underside of the starfish's arms and are used for locomotion, feeding, and gripping surfaces. The suckers enable the starfish to adhere to rocks and other substrates as it moves or captures prey.
What does an ampulla of a starfish do?
Locomotion, gathers food, aids in respiration, and aids in excretion
Who has a water vascular system?
Phylum Echinodermata, which includes starfish, sea urchins, sea cucumbers, sand dollars. It is used to operate the tube feet for locomotion.
What is the organelle for locomotion?
There is no such thing. 'Organelle' is the specialised structure within a cell. It has no relevance to 'locomotion'.
Which structure is found on the outside of a cell and looks like a tail and what it's function?
It is a flagellum and is used for locomotion.
What is the function of the ampulla on a star fish?
The ampulla on a starfish is part of the water vascular system, and stores water and sends it to tiny tube feet on the ventral side of a starfish's arms. This process helps starfish move, as the water vascular system is the part of the starfish responsible for locomotion.
What is the body structure of a sea starfish?
hands
Why madreporic canal of starfish is also called stone canal?
The madreporic canal of a starfish is often referred to as the stone canal because it is a rigid, calcified structure that connects the madreporite, a porous plate on the starfish's body, to the ring canal. This canal plays a crucial role in the water vascular system, allowing seawater to enter and circulate, which is essential for locomotion and feeding. The term "stone" reflects its hardened, mineralized composition, distinguishing it from softer tissues.
