Did you know that a tadpole becomes a frog?

The common pond frog’s life begins in a quiet pond as one of many jelly-like eggs laid together in a mass by the mother frog.

In a few days, the egg hatched into a tiny, legless tadpole that breathes with gills, as fish do.  it has a long tail which it uses for swimming, and eat plants that grow in the water.

Tadpole-to-frog

As the tadpole grows, first two hind legs and then two front legs appears.  After a time the tail begins to shrink and the tadpole loses its gills and gets lungs instead.

Then the tadpole comes to the surfaces of the water to breath air.

At last its tail disappears and the change is complete.

As a young frog, the creature is now ready to leave the water and begin a life as a hoping land animal.

Most tadpole make the change into frogs in the three months of spring.  Most toads begin life a tadpole, much like frogs do. – Dick Rogers

What are barnacles?

Barnacles

A barnacle is a short salt water shellfish that attaches itself to ship hulls, rocks, docks and other underwater objects.  Anyone who goes to the seashore is likely to see barnacles.

A barnacle hatches from an egg as a tiny, free-swimming creature.  But soon it fastens itself to any convenient object, such as the hull of a ship, pilling, rock, or even a passing whale.

Once attached, a hard, limy shell grows around the barnacle. The barnacles stays for the rest of its life in the place where it settles.  It eats by waving its feathery legs through an opening in the shell to pull tiny sea creatures and plants into its mouth.

The shell has a lid that can be closed in case of danger.

To sailors the barnacle is a trouble.  Masses of them clinging to a ship’s hull reduce the ship’s speed.  The only way to remove barnacles’ shell is to put the ship in dry dock and scrape its bottom.  – Dick Rogers
