Fish have fins and not feet.
star fish feel with there tube feet.

Tube feet in a star fish are useful for respiration
The bottom,so they can move
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.
the differences is that a fish has
podia
it's tube feet.
Yes, the tube feet of a living sea star move in coordination to help with locomotion, feeding, and attachment. The tube feet are connected to a water vascular system that controls their movement through hydraulic pressure. This allows the sea star to efficiently navigate its environment and capture prey.
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.
that's easy it goes through the sieve plate, to the stone canal, then into the ring canal , to the radial canal and out the tube feet which are also used for respiration :)
Echinoderms are a group of marine invertebrate animals .They possess spines on skin , tube feet , and water vascular system . Star fish is well known example .
