This document summarizes information about jellyfish and sea turtles, including their habitats and how human impacts affect them. It describes jellyfish habitats in shallow coastal waters down to 12,000 feet deep and notes they come in various sizes up to 100 feet long. It explains how jellyfish populations are increasing due to pollution providing more food and warmer waters. This is negatively impacting fishermen and swimmers. For sea turtles, it provides details on their habitats in oceans worldwide and nesting on beaches. It lists threats including people killing them for food and how they absorb pollution which can make people sick from their meat.

Habitats and Environmental Impacts on Marine Life
Presented by:

2. Georgia Performance
StandardS3L1.
Students will investigate the habitats of different organisms and the
dependence of organisms on their habitat.
a. Differentiate between habitats of Georgia
(mountains, marsh/swamp, coast, Piedmont, Atlantic Ocean) and the
organisms that live there.
b. Identify features of green plants that allow them to live and thrive in
different regions of Georgia.
c .Identify features of animals that allow them to live and thrive in
different regions of Georgia.
d. Explain what will happen to an organism if the habitat is changed.
S3L2.
Students will recognize the effects of pollution and humans on the
environment.
a. Explain the effects of pollution (such as littering) to the habitats of
plants and animals.
b. Identify ways to protect the environment.
c. Conservation of resources

3. Jellyfish
• Phylum: Cindaria (which means that they can sting
you, OUCH! Don’t pick up jellyfish on the
beach, they can still sting you and some can be
very painful and make you very sick)
• There are over 200 Species (that’s a bunch of
relatives)
• They come in a variety of sizes and shapes. The
sizes range from the 1 inch Caribbean jellyfish to
as long as 100 feet (think 6 cars front bumper to
rear bumper in a line) of the Artic Lion’s Mane and
weighing over a ton.
FACT:
Jellyfish have no brain, backbone, heart, or blood

4. Habitat: Jellyfish live mostly in shallow
coastal waters but have been found in
depths of 12, 000 feet
(wow!! that’s deep, that is about the same
depth as the Titanic)

5. • Jellyfish are
known for their
brilliant colors

6. because they feed on dead and dying fish that are
dying as a result of pollution. They like the polluted
environment because they do not have any competition
for their food.
When you add the warmer waters the jellyfish are
becoming a big problem for fishers and swimmers.
The jellyfish are filling the fishing nets of the
fishermen and they are not able to catch the fish
that support them and their families.
There has also been reported and increase in the
number of human deaths that resulted from jellyfish
stings.
Not many organisms feed on Jellyfish but one does!

7. Sea Turtles

8. • Phylum: Vertebrata
• Only 7 species
• Life span = 20-25 years
• Size depends upon species.
• Small Kemp’s ridley
weighs between 80-100
pounds
• Enormous Leatherback
can weigh up to 2000 pounds

9. Habitat:
• Live in almost every ocean basin throughout the
world.
• Nest on beaches
• Migrate long distances to feed. Sometimes
crossing entire oceans.
Spend their entire lives at sea.
• Adult females go ashore
to lay eggs several times per season every 2-5

10. • Have been around for over 100 million
years but in danger of going extinct
• Main threat is people killing them for
food.
• Now they’ve become a hazard for us.
• Absorb pollution from the ocean
• Pesticides
• Metals like mercury
• Also carry salmonella
• Research shows people can get sick
and die from eating turtle meat.
