The Swordtail |
The
Swordtail has a long growth like a sword on his tail, which is how he got
his name he lives in small ponds in South America. If
the pond dries out in summer, he gets to another one across the dry land.
He coils up a like a spring, uses his sword as a lever and does a little
jump. He moves along like this in leaps until he comes to more water. When
he is swimming he uses his sword like a rudder, to steer. In the picture
it has only one sword but they sometimes have two, three, or even five!!! |
