These fish are found from inside waters, bays and channels all the way out to open water, usually along open or patchy bottoms. The sand perch has both male and female organs all at the same time, i.e. it is a hermaphrodite.

It is still difficult to approach the beach for wading. The bricks with holes make walking hazardous and there are only a couple of spots to walk down to the water easily.

Above is a giant red hermit crab in a crowned conch shell. The conch is about 5" long. They are in about 6 inches of water. Note the eyes on the left which look like life saver candy.
Compared to humans, crabs have much smaller eyes and brains but they are still extremely competent in using vision to make snap decisions and spot trouble. This is more than most robots can. Research into how fiddler crabs use vision may one day help robots to act autonomously.
Their eyes are tailored to the specific needs in their flat crab world. For instance, crab eyes see the whole 360 degree panorama around them. They are able to perceive polarized light. The eyes are on stalks like periscopes which fold into protective grooves when the crab enters the burrow. Eyes act as an early warning system, provide compass information for navigation, enable the crab to judge distance, and see birds flying above and predators approaching from behind.

The one above is in the mangrove tops at Quick Point.
I've seen a Great Blue with his wings in this position here once before.

A member of the swimming crabs sought after in nearly every estuary bordering the East and Gulf coast. Grows to 8 inches across its carapace. If you keep a salt-water aquarium don’t introduce this critter into a tank with other species. It is a relentless hunter and you will lose everything else in the tank.
This is a "jimmy", a male crab. It has blue-tipped claws whereas a "sook", a female, has orange-red tipped claws.

Look closely to see the button eyes on the right above and left below.
The sea hare's "horns" can barely be made out below on the left.
