Rainbows Under The Waves: Sea Angels, Sea Pens, and Sea Slugs

Source

Sea Angels and Sea Slugs

We have a name for snails without shells. We call then slugs. Sea angels are just a form of sea slug.

Angels from the deep..

. Because of their appearance they are sometimes called by other names such as sea butterflies or sea faeries.

These angels eat "meat". Clione, or sea angels feed on other snails.

One of the most extraordinary things about sea angels is they can live up to a year without food.

Sea angels "fly" through the water with two diaphanous water wings.


They are native to cold, arctic waters.

One Good Slug Deserves Another

As long as we are slugging away with sea angels, let's look at some more sea slugs.

There are two types of animals which have been referred to as "sea slugs". One type is a snail which may actually be carnivorous and eat other animals. The other is relatively motionless and eats decaying matter that falls to the ocean floor.

Another name associated with sea slugs is "nudibranch".

Some other terms used with underwater snails are gastropod and mollusk. One way of looking at snails in general is to say they have only one foot.

After the slimy sea slugs it's time for the sea pens!

Sea pens resemble the old style writing quill pens that were used a hundred years ago. The old style pens were made of feathers and indeed the sea pen is sometimes called the sea feather.

Sea pens are soft corals that anchor themselves to a soft, muddy surface. They are more mobile than hard coral.

A sea pen is not single animal but a colony of animals. It is sometimes called an octocoral because it is composed of polyps that have 8 tentacles.

Some sea slugs eat sea pens.

Sea pens eat plankton.

If disturbed, the sea can retract.

Beautiful in their own way and fascinating that they can go so so long without food.

FlourishAnyway, we could definitely learn something useful by studying carefully any animal that can do without food for extended periods. There would be many potential uses for such technology. Everything from diet to more efficient energy utilization in every industrial process known to man.
