12 Reproduction Gestation lasts approximately one year and there is a three or four year gap between calving. The estimated lifespan of these dolphins is up to 58 years. BIOEXPEDITION.COM

13 Threats The poor environmental conditions and their habitat degradation are threats for dolphins. This species is protected under the Marine Mammal Protection since 1972. BIOEXPEDITION.COM
