Fall is coming and so are Bud Doyle's Guided Beach Walks...
From mid October 2010 thru April 2011, Bud Doyle will conduct
nature walks at Casperson Beach Park on the second and third
Tuesdays of each month.
On the second and third Thursdays, Bud will conduct guided
nature walks at North Jetty Beach Park.
All beach nature walks begin at 9 am and conclude at 11 am.
They are open to the general public and free of charge.
We'll talk about the Gulf of Mexico, its tides, currents, and storms.
Along the way, we'll identify shells, sharks teeth,birds, fish, and plant life.
Casperson Beach is Venice's rural beach while North Jetty Beach is

a swarm of insects will fly out of an old crab hole.
They look like house flies, but are slightly smaller and lighter in color.
We've never been able to get a good photo of them or an ID.
We bought a new book yesterday with a beach insect page.
There they were! STABLE FLIES (or dog-flies).

are called zooids. Since the group of critters are out of water,
they have closed up and the zooids constitute the main clues to identification.
They are really not gooey at all.
As you can see, the colony has gone through a lot of trials
and tribulations in the surf and on the sand and is still intact.
You will find, if it suits you to pursue their natural history,
that they are a very diverse and difficult group to study.
but everyone knows where his burrow is because of all those tracks.
Sometimes they hide under the sand with only their eyes out.
Ghost crabs grow up to 2 inches wide and eat almost anything..
Combat between males is highly ritualized
and rarely ends with contact.

Here's another sample:
A large, lovely mass of orange turnicate was also on the beach.
We couldn't identify it at that point and
the camera was out of storage space.
Florida fighting conch. The slipper shells can't move much
in search of food, so they have modified their manner of
feeding to trap food with the mucus in the mantle.
Shells have all sorts of interesting behavior patterns.
Slipper shells have both male and female reproductive organs.
In general, the younger,more active slippers are male;
the older sedimentary slippers are female.
Slippers do not self-fertilize. Their male and female organs
operate at different times in their life cycle.

It looks like a plover,
but plovers look very different in the Spring than in the Fall.
Golden plovers look a lot like black-bellied plovers.
We' ll guess : "Golden Plover", because a golden plovers's head
is blacker than a black- bellied plover's head in the Fall.
Maybe, the Auduboners watching can help us out.

"The horse conch (Pleuroploca gigantea), also known as the giant band shell, has been Florida's official state shell since 1969. This shell is native to the marine waters around Florida and can grow to a length of twenty-four inches. Young horse conchs have orange-colored shells; adults have orange apertures.
At least 535 million years ago, mollusks acquired the ability to secrete a carbonate of lime solution that formed a hard, protective shell around them. The word "conch" comes from a Greek word meaning "shell.", "

Other plants like Ulva (sea lettuce), manatee grass,
and sargassum (a brown algae or seaweed) are often washed up
onto the beach. The wrack line or strand line is a line of debris that
often runs parallel to the water’s edge and marks the high tide
line. This wrack, though unsightly, is important. It provides an ideal
environment for microorganisms, amphipods and insects.
