What is an Estuary? Sarasota Bay is an estuary of national significance. Estuaries are places where freshwater mixes with salty water from the sea. Teeming with life, our nation’s estuaries provide vital habitats for 80 percent of the world’s fish and shellfish species.

Estuaries are one of our nation’s most valuable natural resources, creating more food per acre than the richest farmland.

Sarasota Bay Is one of the 28 estuaries in the United States that have been named by the US Congress as an “estuary of national significance.” Established in 1989, the Sarasota Bay Estuary Program is committed to restoring and preserving Sarasota Bay.

The Waters of Sarasota Bay are home to a bountiful natural and cultural heritage that define our sense of place. A sense of place is the culture, heritage and diversity of a region. It is finding inspiration in the past, creating meaning for the present and planning for the future.

Since 1989…. The Sarasota Bay Estuary Program and its partners have had a vision… a vision of a Sarasota Bay with clear waters and abundant habitat supporting a rich diversity of aquatic life …

of people experiencing that abundance while soaking in its natural beauty … and a commitment through education to engage the community to become our partner in cultivating this vision of a healthy Sarasota Bay.

About Sarasota Bay Estuary Sarasota Bay is a coastal lagoonal system formed by a necklace of barrier islands to the west and the mainland of Manatee and Sarasota Counties to the east.

This coastal lagoon, with its unique ecological character of small embayments, tidal tributaries and small creeks, coves, inlets and passes, stretches from Anna Maria Sound to just north of the Venice inlet.

Sarasota Bay is made up of a series of seven smaller bays or embayments. Each is nourished by fresh water tributaries that gather stromwater from the adjacent lands (watershed). Each of the embayments is unique.

They differ in overall size, shape, water depth, shoreline features, habitat and sediment characteristics. Because of these differences, each embayment must be analyzed and managed independently from the others while at the same time recognizing their connectivity.

The Sarasota Bay Estuary Program is dedicated to restoring Sarasota Bay through the following ways:

Habitat Restoration Restoring the historic balance of native wetland and intertidal habitats.

EcoTourism The Gulf Coast Heritage Trail connects those special places that weave together the fabric of our history.

Neighborhood Action Center Protecting health of Sarasota Bay begins in your yard. 1.Fertilizers 2.Pesticides 3.Laundry 4.Watering

The Water Connection You are the solution to the storm water pollution.

Educational Outreach Engage, educate and encourage You can get involved as a Sarasota Bay Guardian Volunteer with the Sarasota Bay Estuary Program.

Environmental Research Acquiring the necessary data to make informed management decisions. Millions of tiny scallops, and hope for the bay’s future … seeding the waters: It’s a collective effort to try to boost bivalves’ numbers.

Celebrate Our Accomplishments 1.Water quality has improved in all bay segments. 2.Seagrass beds are recovering 3.Bay scallops have returned 4.Restored wetlands and artificial reefs are creating new habitat for marine life 5.Recreational fishing is excellent 6.The community has upgraded wastewater treatment plants and initiated stormwater run-off prevention projects.

In Module 6 we have studied Vertebrata: 1.Class Agnatha (Jawless fishes) 2.Class Chondrichthyes (Cartilaginous fishes) 3.Class Osteichthyes (Bony fishes)

Module 7: Marine Vertebrates II In subphylum Vertebrata, there are four more major classes: 1.Amphibia (The Amphibians) 2.Reptilia (The Reptiles) 3.Aves (The Birds) 4.Mammalia (The mammals)

Class Reptilia pg. 159 Alligators, lizards, snakes and turtles. These animals are covered with trough, dry scales that help prevent water loss. Many of these reptiles breathe air with their lungs and must return to the surface of the ocean to breathe. There eggs are laid on dry land.

Thermoregulation Some biologists consider most reptile species to be behavioral thermoregulators in that they can and do move themselves in and out of sunny and shady areas to regulate body temperatures. They do not have internal mechanisms for maintaining constant body temperatures like endotherms, but they use external conditions.
