Scrawled cowfish
This 8" scrawled cowfish was found way up on the beach at South Lido Beach. It appears to have been out of the water for quite some time and is unusually pale. When alive, it would be gold to yellow with broad blue lines. The hexagonal patterns on its body help distinguish this cowfish from others in the same family. Aquatic gem turns 50

Bird Key Park Construction
Hurrah! Work is progressing at Bird Key Park off Ringling Bridge in Sarasota. The west end was completed earlier this summer with walks, trees, kayak launch, and swinging seat under a blue canopy. We can't wait to see what this east end will look like.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.

Crab Eyes
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.
