Sammy’s experience with the shark was still fresh in his mind, and for a time he kept close to the ledge ready for a dash to safety should danger again threaten.

It was a most interesting place to explore, this ledge. There were big rocks and little rocks, flat rocks, rocks hidden by mud and sand, and sharp, jutting rocks full of peril to ships at low tide.

In one or two places near the ledge the ocean was so very deep that Sammy never ventured to explore its depths, while from another point he could clearly see the sand at the bottom of the sea, and loved to descend and swim lazily about examining the shell-fish, sea-snails and other curious creatures that made their home there.

The long ledge had many inhabitants and Sammy was soon on very good terms with a couple of jolly sea-urchins, whose round, prickly bodies were half hidden in the little holes which they had bored in the rock. The sea-urchins made him acquainted with some relations of theirs, a family of star-fish living on a flat shelf of rock near by. The star-fishes proved very agreeable companions, being both polite and pretty. They had lovely orange colored backs, out of which protruded their five arms, or rays, giving them the star-like appearance from which they get their name. Under these rays were rows of tiny feelers, or suckers which they used as feet. With these a star-fish can crawl about, or even turn himself over if he wishes to, and if he is disturbed or frightened these little feelers shrink up and conceal themselves in tiny holes in the rays.

Some star-fishes have the power of breaking off their rays, and, like the crab and lobster, can grow new ones to take their place. They have many beautiful relations in the star-fish family, one of the loveliest being the Brittle-star, so called because it will break in pieces when touched. Another relative is the Sun-star, which has twelve or fifteen rays, and often grows to a very large size. Its color is sometimes purple, sometimes red, with white rays tipped with red; truly a gorgeous creature, and no doubt very vain of his wonderful beauty!

All star-fishes have mouths and stomachs, which they put to good use, being exceedingly fond of oysters, and such like, which they suck out of their shells when opportunity offers.

One of this particular Star-Fish family, Meteor by name, proved very friendly indeed to Sammy, and through him our hero learned of a fine Oyster Colony which had established itself on a mud bank not very far distant.

STAR-FISH.
