Behavior
You will find the Fraser’s dolphins in groups from 100 to 1,000. They always swim very closely together. These are very fast swimmers and then tend to engage in that behavior throughout the day. They are believed to be among the most aggressive of all species of dolphins. They won’t attack humans but they stand their ground against each other as well as enemies.
Diet and Feeding
These dolphins feed on a variety of common foods. They including squid, small fish, and shrimp. They tend to feed well below the surface of the water. Therefore they rely upon vibrations of their prey to help them find them. They are great hunters and do so in groups. This allows them to circle entire schools of fish. It is common for them to dive about 2,000 feet for food.
Reproduction
Mating takes place in the spring, with the pups being born the following spring. It takes just over 12 months for the process to be completed. Males are ready to mate about 10 years of age and it is about 8 years of age for the females.
