2. SharksThere are more than 465 known species of
sharks living in our oceans today. Sharks
are an apex predator at or near the top of
their marine food chains, and they
regulate the populations of species below
them. Research has shown that massive
depletion of sharks has cascading effects
throughout the ocean’s ecology systems.

4. Octopuses are sea animals famous
for their rounded bodies, bulging
eyes, and eight long arms. They live
in all the world’s oceans but are
especially abundant in warm,
tropical waters. Octopuses, like
their cousin, the squid, are often
considered “monsters of the deep,”
though some species, or types,
occupy relatively shallow waters.

6. TortoiseSea turtles are one of the Earth's
most ancient creatures. The seven
species that can be found today
have been around for 110 million
years, since the time of the
dinosaurs. The sea turtle's shell, or
"carapace" is streamlined for
swimming through the water. Unlike
other turtles, sea turtles cannot
retract their legs and head into their
shells. Their color varies between
yellow, greenish and black
depending on the species.

8. Fish Living among the tentacles of
the anemone, the clown
anemonefish gains protection
from predators—which don't
dare get near the stinging
protector. The anemonefish
also gets to eat leftovers
from the anemone's meals.
The anemone benefits from
having the fish around, too.
