STARFISH or SEASTARS Generally Description: Starfish are star shaped animals that live in the bottom of the sea.
Their family name is "Echinoderm" which includes: Brittle stars,
Sea Urchins, Sea Cucumber and Sea Stars.
It's mouth is in the middle of it's body and it's eye's on the end
of it's legs. It can grow up to 24 legs. It has spiney skin and
that's why it's called an Echinoderm which means "spiney skinned".
To walk it has small tubes like sticky pads which help it walk up
rocks or along sand.
Starfish can grow up to 10-30 cm in diameter. There are OVER
100 different types of Starfish, so scientists are still
studying hard on them
Interesting Facts: The Starfish can actually pull open a shell!
If it finds a mussel or other mollusc it pulls open the shell
and eats the inside, they do the same with shell fish
The Starfish can come up to 3000 members within one area.
If a Starfish looses four of it's five legs it can grow them
Food and Eating Habits: The starfish eats mostly molluscs but it eats sponges, corals
and even seaworms! Predators and defenses: If a mussel or clam that a Starfish eats is sick or dead the
starfish may die and it's very lucky if it lives. Habitat/Location: The Starfish live mainly on the bottom of the sea but it also
lives in small holes left by other creatures in rocks and coral
reefs. The second main place to find Starfish is on coral
because the starfish nearly always eats it!
Behaviours: If a Star fish finds a piece of food, such as a muscle, it sends
off food signals. Soon, all the Starfish that got the message
come and start fighting over the food, like a flock of seagulls
with a fish or something.
Breeding/Rearing Young: When mating season comes all the female starfish send off eggs.
The male senses them and sends off sperm. The eggs and sperm
join together and make a baby.
Conclusion: The starfish is a very strange creature and many scientists
are still studying very hard on them. The starfish can be
