Is the sea anemone a plant or an animal?

When it is time to feed, the sea anemone will open up like a flower.

The sea anemone (pronounced “un NEM oh nee”) is a strange sea animal whose many graceful tentacles (tiny arms) often look like the petals of a flower.

Sea Anemone

A cluster of sea anemones looks very much like an undersea garden of brightly colored, red, purple, green, and blue blossoms.

Although sea anemones may look like harmless flowers, their touch means death to small fishes and other small sea creatures.

When a small fish happens to swim too close to the sea anemone and touch the tentacles, tiny, needle-like poisoned threads shoot out of the tentacles and sting the fish.

Then the tentacles drag the helpless prey into the sea anemone’s mouth.

The foot of the sea anemone allows it to slide about slowly on rocks.  But usually, they anchor themselves by gripping rocks, shells, or burrow into the sandy floor of the ocean.

Then a sea anemone is disturbed, it pulls its tentacles inside the body.  It then looks like a round lump on the rock. – Dick Rogers

What does the blue whale eat?

As big as the blue whale is, it eats only the tiniest plants and creatures in the ocean.  A giant blue whale 100 feet long and weighing nearly 150 tons makes an elephant look small.

The blue whale is perhaps the biggest animal that ever lived.  But as big as the blue whale is, it eats the smallest bits of food it can find in the oceans.

Blue Whale

The blue whale has no teeth, so it can’t chew food, and its throat is so small that it can only swallow small fish.

So it eats mostly tiny plants and sea creatures called plankton that drift about in the ocean.

Instead of teeth, long stringy plates of whalebone hang like curtains from the top of the blue whale’s mouth.  They are used like a strainer.

To eat, the blue whale swims through the plankton with its mouth wide open.  The blue whale then squeezes the water out with its big tongue and swallows the plankton trapped on the whalebone.  It takes barrels of plankton to fill the blue whale’s big stomach.

There are other toothless whales, but some whales have strong teeth, such as the killer whale, and throats large enough to swallow chunks of food. – Dick Rogers

What is an albatross?

Albatross

Some birds spend all their time far out at sea, except when they are nesting.  The albatross is one of these birds.

It is a large sea bird resembling an overgrown sea gull.

Albatross are found roving over nearly an ocean except the North Atlantic.

They often follow ships for days and feed on the garbage that is thrown overboard.

Their long, narrow wings, allow them to soar behind a ship for hours with barely a wing beat.

Albatross sit down on the water to eat and scoop up the scraps of food with their yellow, hooked beaks.  They also eat fish.

The best known albatross is the wandering albatross.

This magnificent white bid has the longest wingspan of any living bid.

Though only about nine inches wide, its black-tipped wings may stretch more than 11 feet from tip to tip

An old sailor’s superstition said that harming an albatross bought bad luck.  – Dick Rogers
