First few paragraphs written in writing class, from Starfish to Oysters to Pearls

 

Special features

By Leonardo Davis (9 years)

Starfish, which are not fish, are actually sea stars and they can be found all over the world’s oceans.  There are over 2 000 kinds of sea stars.   Importantly they eat oysters and clams.  Most have five arms, but some have even ten or twenty or even forty arms.  They can also extraordinarily grow another arm into a body, because they have special organs in their arms.

 

 

 

Extreme facts

By Leonardo Davis

Bivalves, which are marine animals, have two shells, one at the top and one at the bottom.  Bivalves are mostly valuable, because they produce pearls.  Commonly they live in the shallow, warmer waters.  The female oysters produce five million eggs per year, but few mature. The shell forms one day after fertilization.  They can swim one day after hatching.  They must attach to objects under the sea and lives for the rest of their live there.  Another extreme fact is that the adult is two to ten inches long.

 

 

 

How pearls are made

By Leonardo Davis

Oysters are useful for food and the production of pearls. If an object finds its way into the mantle of the oyster it causes and irritation. It secretes a mother-of-pearl substance around the object. Over time, layers and layers of the substance must form around the object to form a pearl. Japanese discovered a way to artificially encourage the oysters to form a pearl. It takes three to four years to form one single pearl, and that is how pearls are made.
