Biology of the species
Adults are usually 1.3-1.5 metres long and weigh around 30 kg. Females are slightly larger than males, which is not typical for other dolphins.
It has a short head with a rounded blurred face, making it look different from other dolphins.
The low dorsal fin has a triangular shape with wide base, pectoral fins have rounded ends. The back of the body is dark grey, sometimes almost black, the abdomen is light. Females which reach adulthood (4 years), reproduce in late spring - early summer. Pregnancy lasts 9 to 11 months, females bring one cub, which is born with his tail in front and must immediately rise to the surface for its first breath.
This subspecies faces pressures from marine traffic.
