Page 1- The written portion
• 400 sq. miles, watershed is 6X’s that size
• 4 major rivers: Hillsborough, Manatee, Little Manatee, and
Alafia
• Over 100 + creeks
• Phytoplankton is the primary producer in the food web
• More than 200 + fish species
• 5 counties: Hillsborough, Pinellas, Polk, Pasco, and Manatee
• 40,000 pairs of 25 different species of birds. Most diverse in
N. America
• Average depth = 12 feet, largest shipping channel = 43 feet
deep / 40 miles wide
• More than 4 billion gallons of oil, fertilizer components, and
other hazardous materials pass though the bay each year.

Red Mangroves, Rhizophora
mangle
Black Mangroves, Avicennia
germinans
White Mangroves,
Laguncularia racemosa
• In the water / closest to the
water
• Really high prop roots / stilt
roots= prevent erosion /
provides stability
• Thick leaves reduce water
loss
• Seeds are long, pencil
shaped seedlings called
propagules.
• More like a bush
•Between the red and white
mangroves
• Fingerlike projections that
stick up out of the sediment
are called pneumatophores.
They serve as a ventilation
system.
• Salt glands on the surface of
the leaf that secrete salt. The
leaves glisten.
• Seed = fruit embryo
• Looks more like a tree
• Grows higher in elevation by
land
• No visible root system
• Two visible salt glands at the
base of the leaf
•Yellowish / green leaf
• Seeds look like a sunflower
seed.

• Have to be exposed to air
• Experience high salinity levels due to the intertidal
exposure
• Biological filters for terrestrial run-off
• Grow in anoxic sediment (low oxygen) and have to
tolerate higher levels of salinity due to evaporation
• Facultative Halophytes= tolerate SW and FW conditions.
• Importance:

–
1. Refuge, feeding ground, hiding spot
2. Nursery
3. Detrital food chains
4. Stabilize sediments to prevent erosion
5. Recycle phosphorus, filter run-off (remove toxic organic
pollutants)

Page 12- Spartina alterniflora
Physical Structures:
- Grow in tufts of vertical stems connected by rhizomes.
- Vertical stem= culm, which produces additional stems
called tillers (format the base making it look bushy)
- Roots are at the culm
- Rhizomes-> connected root system
- Leaves have a thick cuticle to slow water loss
- Highly developed vascular system for efficient transport
of water
- Leaves- have salt glands= secrete salt to the outside,
which prevents salt toxicity

• Spend about 8 hours a day eating
• They eat FW and SW plants
• During the cold winter months they migrate to warm waters
(ex- power plants and springs)
• Use its flippers and tail to steer itself through the water and
moves its tail up and down to move forward (FWC, 2014).
They can do somersaults, rolls, and swim upside down
• Surface to breathe every 5 minutes. Can hold their breath for
20 minutes (during resting)
• 13 month gestation period
• Six cervical vertebrate, most mammals have seven. They can’t
turn their heads sideways, instead they must turn their entire
body.
