THE STARFISH
One of mi favourite animals of the sea is the STARFISH or SEA STARS because is amazing that they can regenerate lost arms. This is useful if the sea star is threatened by a predator. The starfish can drop an arm to get away. .
While the five-armed varieties of sea star are the most well known, not all sea stars have 5 arms.
KINGDOOM:
The natural kingdoom of the starfish is the sea.
There are over 2,000 species of starfish
CHARACTERISTICS:
SEA STARS ARE NOT FISH
Starfish are echinoderms (spiny skinned sea urchins).
Starfish cannot swim, and they do not use gills to breathe
Starfish have hundreds of tiny projections known as tube feet on the underside of their body. The tube feet allow the starfish to move along the ocean bottom and open upon the scallops and clams they hunt for food.The starfish has two stomachs.
The starfish have microscopic eyes at the end of each arm; this enables the starfish to view movement and differentiate between light and dark. They don’t, however, see much detail.
FUN FACTS:
Sea stars house most of their vital organs in their arms, so some can even regenerate an entirely new sea star from just one arm and a portion of the star’s central disc. It takes almost a year for this to happen
