               Food/Diet
Bottlenose Dolphins fish near the surface
Newborns will drink their mothers milk while the
“aunt” guards them
They will eat any type of fish or squid
In order to find food they use echolocation
With echolocation they can “see” the size,
shape, distance, speed, direction, and internal
structure
Adults eat 15-20 pounds of food a day
             Predators

Bottlenose dolphins don’t have many
predators.
Some Predators are:
Sharks (tiger sharks, dusky sharks and bull
sharks)
And Orcas
        Social Groups
Bottlenose dolphins live in small pods of
up to 12
They don’t stay with the same pod all the
time, they swim away when they want to
Some stray but most stay in a group of
some sort (not always the same)
Most dolphins stay in one pod or another
for safety reasons
       More Facts

Some scientists believe that bottlenose
dolphins are capable of complex
communication skills
They can also rescue people from danger
