Ark clam is the common name for a family of small to large-sized saltwater clams or marine bivalve molluscs in the family Arcidae. Ark clams vary both in shape and size. They number about 200 species worldwide.
The shells of ark clams are often white or cream, but in some species, the shell is striped with, tinted with, or completely colored, a rich brown. In life the shell of most species has a top shell layer that is thick brown periostracum affixed to the harder calcareous part of the shell. In some species such as Barbatia, this outer horny covering is tufted at the end of the shell into something that resembles a beard, hence the name Barbatia or bearded one.
The group is known as "ark shells" because species such as Arca have a large flat area between the umbones which, in an undamaged shell, somewhat resembles a deck, with the rest of the shell perhaps illustrating an ancient wooden boat such as Noah's ark is thought to have been.
All ark shells have a long straight hinge line with a single row of numerous small and unspecialized "teeth". This is known as a "taxodont dentition" and represents an ancient ancestor. This kind of hinge line is also found in the bivalve families Glycymerididae, Nuculidae and Nuculanidae.
A long day is winding down
The neighbors are arriving
The street noise is dying away
As they go into hiding
The mail says lots of things
I find no use in knowing
It sits, closed, atop the bin
your name, my address showing
But there?s a sunset
Over hope street
There?s a sunset
Over hope street
I want to wish
To wish you what you want
Most times it?s plain to see
You?re driving someone crazy
But then there are other ones
When someone just gets lazy
And there?s a sunset
Over hope street
There?s a sunset
Over hope street
I want you wish
To wish you what you want
There?s a sunset
Over hope street
There?s a sunset
Over hope street
But you are what
Yeah you are what I want
But you are what
