Behavior
They are excellent when it comes to communication. They use a variety of loud clicks and whistles to talk with each other. They form groups of about 50 and they are also known to move around with other species of dolphins without any conflicts among them. There is a hierarchy among these dolphins that depends upon many factors including their size, age, and gender.
They are extremely protective of their young and will help each other to care for them. They also tend to do their best to protect the pregnant females from enemies including sharks.
Diet and Feeding
Their main food sources include octopus and various types of small fish. Most of the time they will fish at night. They also tend to hunt in groups as they have a tactic that allows them to get their prey into a big circle. Then they are able to come at these schools of fish from all angles.
Reproduction
There isn’t too much known about the reproductive habits of these dolphins. It is estimated that it takes 11 months from mating to birth. They are born without any spots but about one year of age they begin to develop. It is along this same period of time that the mothers will stop offering milk to them.
