Type: Group Layer

Geometry Type: null

Description: <metadata></metadata> Risso’s dolphins are very robust with an average adult body length of 3.2 m.At birth calves are grey (overall colour ranging from light to dark grey) with a paler underside.As they age, adult Risso’s become paler due to increasing levels of white scarring resulting from tooth rake marks gained during social interactions. Adult Risso’s appear pale grey or largely white (depending on levels of scarring), particularly around the head.There is a white anchor-shaped patch on the chest and the underside of the belly is also typically white.The head is blunt and bulbous, with no evident beak.A distinct vertical cleft is evident on the front of the melon. A tall, dark and very prominent dorsal fin is located mid-way along the back.The tip may be rounded or pointed with a concave trailing edge.The pectoral fins are long, dark and sickle shaped.A small but noticeable blow may be seen at close range. Risso’s dolphins can be very acrobatic at the surface with repetitive breaching and tail slapping.
