5. 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
6. Predators Bottlenose dolphins don’t have many predators.
Some Predators are:
Sharks (tiger sharks, dusky sharks and bull sharks)
7. 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
8. More Facts Some scientists believe that bottlenose dolphins are capable of complex communication skills
They can also rescue people from danger
