Mostly about my backyard chickens. (Boring, I know), but there are a lot of us out here. Mine are only kept as pampered pets. I could eat a neighbor's chicken, but not MINE. There may be a comment on current events only if I get riled up enough. And there will always be a cartoon or a joke to cheer us. I promise to try my very best to respond to comments. Now I have to figure out how this blogger thingy works....
The gang was let out of the pen an wandered all over the place!
This is Louise - she ALWAYS looks startled!

First time this year without a blanket!
Just some pine cones - 4 of 'em on a branch:
Those silos belong to the riding academy down the road - when the
leaves come on the trees, I won't be able to see them:
Still patches of snow left:
Charlie & Betty looking for goodies:
Was good to finally get to stay outside for a while - don't know how long this break in the weather is going to last, but I'm sure going to take advantage of it!
It is easy to walk down a pretty sand beach, with waves sloshing back
and forth, and imagine that there is little life along the edge of the
sea. There is no vegetation growing – there is just sand.
Actually, the margin of the sea is alive with a host of organisms who
have figured out how to exploit the unique environment and its
seemingly invisible wealth of organic foods.
One of the masters is the mole crab, Emerita portoricensis. Not the
large edible variety to which we are accustomed, this inch or so long
critter looks more like a shiny bullet, being smooth shelled and tapered
at both ends. They do not bite or pinch humans, and they cannot walk.
Their limbs are adapted for burrowing and swimming.
Mole
crabs make their living in what is called the surf zone where waves die
as they move up the beach face, then slide back into the sea. When
there is no water, the sand seems impenitrable. A person can walk across
it and not sink. When the water washes across the sand, any slight
aggitation easily separates sand particles and the sand becomes a thick
fluid. This is called thixotropy, and allows access to the sand as a
place to hide as well as a place to dine.
This is where the mole crab excells. As the water momentarily covers
the sand, mole crabs appear in the water, swim about frantically looking
for a new dining room, and disappear beneath the surface, leaving only
their antennae exposed on the surface to funnel food particles into
their mouths. If one squats and looks down the beach face, the antennae
appear as little Vs along the sandy surface.
Mole
crabs normally feed on plankton and other small organisms in the water,
but they are also known to eat the toxically armed tentacles of
Portuguese man o’ war, a jellyfish whose stings are very painful to
humans..
Mole crabs are an excellent example of an animal that has perfectly
adapted to living in a specialized environment. Be sure to look for them
on your next visit to the beach.
