The starfish life cycle starts anew when eggs and sperm are released into the ocean and fertilization occurs. Starfish larvae result from fertilization of the eggs. The larvae later undergo metamorphosis and eventually turn into adults.
Starfish don't swim they crawl around very slowly on rocks in the ocean on their "feet". Sometimes the current can unstick them from their rocks and make them momentarily be "waterborn" but this is not swimming.
The starfish has radial canals that go through all the legs and join in the center to make the water vascular system that functions as a circulatory system, waste removal and more.
A sea star develops from a very small larva
They have an open and reduced circulatory system, consisting of a central ring and five radial vessels.

With tentacles which are under their bodies!
It's the hemolymph.
can a starfish swim?
They eat and move around.
because that's the way they are and they suck into the floor and move from left to right
because a sea star has 5 legs A starfish has legs that are placed horizontally around its body, so it can maneuver in any direction. Some studies indicate that some starfish may favor some of their legs and move in a particular direction most of the time, but these studies are inconclusive. The starfish doesn't creep around the ocean floor with its arms! They actually use tiny tube feet to move around. If you turn a live starfish over you will see its tiny tube feet wiggling back at you.
Starfish can move about.
No, starfish can move. Coral cannot move. Starfish have a mouth with which to eat. Coral bring in nutrients through tendrils.
The starfish doesn't creep around the ocean floor with its arms! They actually use tiny tube feet to move around. If you turn a live starfish over you will see its tiny tube feet wiggling back at you.Starfish, or sea stars, move with their tube-feet on the underside of their body.
It farts to move
Starfish have limbs so that they can wrap them around their prey(mostly clams,mussels, etc.) and hold onto them entil they can open the prey up and eat it.
starfish are around ,1.5inches
The water vascular system of a starfish helps it move around by creating hydraulic pressure that powers the tube feet. These tube feet are connected to canals that run throughout the body of the starfish, allowing it to extend and contract them. By controlling the amount of water in the tube feet, the starfish can use them to grip and push off surfaces, enabling movement.
Trains.
starfish have really small leg type things. they use these to walk.
