Starfish
Also known as sea stars, these echinoderms are 2,000 species strong and found in seas and oceans all over the world. They can vary in size from less than half an inch to more than four feet across.

The one thing that I’m focused on, are sponges. SPONGES. Many people believe that the type of sponges we’re talking about, are the sponges we clean with... well, you’re wrong. The sponges that scientists keep trying to explain to people that live in the ocean, sea sponges. Now I’m worried for sea sponges, because starfish keep eating them. And frankly I feel very bad for their habitats. Because the ocean needs the sponges help. The ocean relies on porifera/sponges to help the ocean, to help it grow, to help it prosper, and to help animals live and eat.
Do sugar starfish give birth to eggs?
By hatching do you mean laying? Because if something comes out of an egg that process is called hatching. But yes, if laying was the term you meant then starfishes DO lay eggs.
Starfish lay millions of eggs. In a single instance, they release up to 1,000 eggs which are met and fertilized within the water columns by the male ones released simultaneously. At two years, cushion starfish are mature males and at four years they change into female.
Hope this helps!! ;)
Most species of starfish eat mussels and other mollusks, or shellfish. Small starfish need to be on the lookout for larger starfish, which will sometimes attack, kill and eat them. Manta rays, some sharks and other large, bony fishes eat starfish.
How can a starfish be destroyed?
The only way a starfish(sea star) can die is if it is dried up. If it is split in half, both halves live and can come together again. It's really weird how this works, but, hey, life's life!!! "Starfish occasionally lose one of their arms due to predation or other injury. Most of the time they are able to regenerate the missing arm. In fact, sometimes a starfish arm can regenerate into an entirely new starfish, but usually only if a portion of the central body is still attached to the arm."(Taken from site listed below)

It has some cool pictures and facts! Check 'em out!!!!
What is the ecosystem of the starfish?
Starfish habitats and living conditions are interesting. They live on the bottom of the sea and near rocky areas. This is a cool animal! They can also regrow their body parts.

How does a starfish defend itself?
A starfish is unable to bite because it lacks teeth. When a starfish eats, it lays on its pray and throughts up its stomach, similar to a fly, it then eats it stomach again with its prey.
Can starfish be fast swimmers?
No, starfish walk along the bottom and on rocks either on tube feet, or in serpent stars, they pull themselves along with the arms.
What to do when starfish lose all legs?
If a starfish loses all of its legs, they will grow back. This regeneration is asexual reproduction. We just learned about that
Feather stars feed on tiny drifting organisms and particles, gathering these passively from the water by adjusting their arms to maximise the feeding area relative to the water flow.
How do sunflower starfish feed?
They eat clams, snails, abalone, sea cucumbers and other sea stars. In Monterey Bay, California, they will feed on dead or dying squid. Although the sunflower seastar can greatly extend its mouth, for larger prey, the stomach can extend outside the mouth to digest prey, such as gastropods like abalone.
How do starfish protect it self?
If a ray of a star fish is cut off and is not damaged than it can regenerate into a whole new starfish! That way they will not go extinct.
it grbs them with there suckers and its hurts them
No, the correct name is Sea Star. All fish are Vertebrate chordates. Sea Stars do not have a hollow notochord (chordate). Sea Stars belong to the Phylum Echinoderm (spiny skin). Other members of this Phylum are the sand dollars, sea urchins and sea cucumbers.
On the surface of a starfish you will find spines used for protection as armor, dermal gills surrounded the spines, a central disk, madreporite, arms and an anus. Underneath tubed feet used for movement, mouth, ambulacral grooves, and its mouth.
A starfish's 'mouth' is on the bottom, centered. To get food, it will find a nice, tasty mollusc like a clam, use its arms to pry open the shell, and then suck out the contents with its mouth.
Most starfish are any of the following colors: pink, orange, red or grey. Though there have been cases where they can be a different color such as white.
How are dolphins and sea stars alike?
They both live in the sea. Otherwise they have virtually nothing in common. A dolphin is a mammal like dogs and humans which a starfish is a crustacean like a crab. BUT, they both have brains, therefore they think. They both have senses, therefore they 'see'. And they both have excrement. But other than that, they have nothing in common, lol.
obviously multicellular single celled organisms such as bacteria are unicellular.
Does starfish stinks when dead?
Most organisms undergo a process called rigor mortis when they die. This is due to the fact that muscle movement requires energy (in the form of ATP). ATP is generated by respiration which can only be carried out by the mitochondria of living organisms. Therefore a dead organism cannot produce ATP so its muscles remain locked shut making it stiff. If you take a starfish out of water its skin will undergo a process called dessication which essentially means drying out that makes it harder and spikier than normal. Interestingly starfish are in the phlya echinodermata which translates literally as spiny skin.
What organ is the starfish's mouth connected to?
it helps eat predators and other things and digests the food it eats
