Orcas are predators that live in oceans around the world. Predators like orcas hunt other animals for food. Orcas are commonly known as killer whales however they are
actually
part
of
the
dolphin
family.
Like
dolphins,
orcas
are
very
social as a result they
live
in
groups
called
pods.
Orcas
build
close

Sound
is
very
important
for
orcas.
They
make
noises
underwater
to

use
clicks
and
whistles
to
communicate
with
others
in
their
pod.
Every
pod
has
its
own
unique
pattern
of
sounds therefore scientists
can
identify

that
are
from

for

Many

are
harmful

Loud
noise
from
boats

can
echo
underwater
for
miles.
Those
echoes
make
it
difficult
for
killer

to
hear
information
from

becomes
harder
for
them
to

People
have
learned
that
killer

hunt

and
travel

when
there
are

Many
orcas
are
forced
to
swim

to

This

Slower

Answer 1

Here is the revised passage with punctuation correctly added:

Orcas are predators that live in oceans around the world. Predators like orcas hunt other animals for food. Orcas are commonly known as killer whales; however, they are actually part of the dolphin family. Like dolphins, orcas are very social; as a result, they live in groups called pods. Orcas build close relationships with the members of their pod. Sound is very important for orcas. They make noises underwater to help them hunt. In addition, orcas use clicks and whistles to communicate with others in their pod. Every pod has its own unique pattern of sounds; therefore, scientists can identify killer whales that are from the same group. However, not all sounds are good for killer whales. Many human sounds are harmful to them. Loud noise from boats and drilling in the ocean can echo underwater for miles. Those echoes make it difficult for killer whales to hear information from their own noises; as a result, it becomes harder for them to hunt and communicate with their pod. People have learned that killer whales hunt less and travel more when there are many noisy boats nearby. Many orcas are forced to swim to quieter places or call more loudly to find the food they need. This takes a lot of energy, causes stress, and makes it harder to survive; therefore, some coastal communities have started to limit boat traffic to protect killer whales from the noise. Slower boats are quieter in the water; in addition, it is easier for boaters to see and avoid orcas when they travel at lower speeds.
