Behavior
These dolphins form small groups of no more than 30 members. Yet some researchers have found groups of more than 1,000. It is believed that these are isolated incidents. Further studies show that it may coincide with some form of migration or mating rituals. That would bring many smaller groups together to pose as one larger one for that period of time. Even after a great deal of observation, there aren’t any identified patterns of hierarchy behavior among this species of dolphins. For many others that is based upon age, size, and sex. These groups don’t seem to have leaders or followers but to be in sync with each other completely.
Diet and Feeding
They tend to hunt for food at night, going very close to the surface of the water to find it. They feed upon squid, mackerel, various types of small fish, and shrimp.
Reproduction
Sexual maturity occurs about five years of age for both the males and females. After mating occurs the offspring will be born from11 to 12 months later. The offspring will consume milk from the mother for the first year of life. However, the mother won’t conceive the following year. Generally there is 26 months between the time she has a pup and when she mates again. Stenella attenuata
