What else can I help you with?
What kind of circulatory system does a sea otter have?
Sea otters have a closed circulatory system.
Do sea urchins have an open circulatory system?
All vertebrate animals (animals with spines) and a few invertebrates ("echinoderms" - starfish, sand dollars, sea urchins, and sea cucumbers) have closed circulatory systems.
Do sea stars have an open or closed circlitory system?
Sea stars use their water vascular system for circulation, excretion, and movement. This is a closed circulatory system because the fluids (water mostly) all travel through a series of stone, radial, and ring canals.
What type of circulatory system does sea lions have?
Sea lions have a closed circulatory system, which is typical for mammals. In this system, blood is contained within vessels and is pumped by the heart, allowing for efficient transport of oxygen and nutrients throughout the body. This adaptation supports their active lifestyle both in the water and on land.
What is the adaptaion of a starfish?
It is a sea star! So many people make this mistake.Anyway, some adaptations of a starfish are on some sea stars, they have thorns.They can grow back broken limbs.They have a seawater circulatory system that powers their feet.
What are some examples of natural fluid?
Some examples of natural fluid systems are: 1.Our body's circulatory system and respiratory system. 2.The movement of sap in trees 3.The movement of sea stars: Sea stars have several rows of tube feet with suckers at the end. Each tube foot contains fluid. The pressure in the fluid changes when a sea star contracts its muscles. These pressure changes allow the sea star to move and gather food.

What system does a sea star NOT have?
Starfish do not have a brain.
The tube feet of a sea star take advantage of what principle to move?
The tube feet of a sea star move through a hydraulic system known as the water vascular system. This system uses water pressure to control the extension and retraction of the tube feet, allowing the sea star to move and manipulate objects.
How much force can the water vascular system of a sea star generate?
The water vascular system of a sea star can generate enough force to extend and retract tube feet for movement and feeding. The force is sufficient for the sea star to grip onto prey items and surfaces. The exact amount of force generated may vary depending on the species of sea star.
Why is it said that the earthworm has a closed circulatory system?
It only has one flow of blood.We have two flows of blood, one for the lungs and one for the body. This also means the worm will only have two heart chambers while you have four.P.S. This is the third question on circulation i have answered today, is this someone typing in all their homework questions?
