Long beaked Common Dolphin
Delphinus capensis

Classification
Scientific Name: Delphinus capensis

Other Names: none known

Suborder: Odontoceti

Family: Delphinidae 

Description
The Long-beaked Common Dolphin is slender with a broad, dark cape which dips into a V-shape just below the dorsal fin,  an ochre (though sometimes pale) thorasic panel and grey colouration on the tailstock which forms a distinctive horizontal hourglass pattern.

Unlike the Short-beaked Common Dolphin which is very similar, the Long-beaked Common Dolphin has a longer beak, flatter melon, more muted patterning and, in addition to dark eye-flipper stipes, has a dark eye-vent stripe.

They are very gregarious and vocal, often porpoising, breaching and bowriding. They can be seen associating with Short-beaked Common Dolphins in some areas but usually prefer warmer, inshore waters.

Female: 1.9 -2.2m
Calf: 0.8 - 1m

Maximum Weight
