A pod of about 70 bottlenose dolphins spend much of their time swimming around Jervis Bay between Huskisson, on Jervis Bay’s southern side, and Red Rock, near Callala Bay, on Jervis Bay’s northern side. Many of the dolphins are grey bottle nose dolphins, but at times, rare albino dolphins have been spotted in the pod. Take a dolphin cruise. Click here.

Bottlenose dolphins live in groups typically of 10-30 members, called pods, but group size varies from single individuals up to more than 1,000. Their diet consists mainly of forage fish. Dolphins often work as a team to harvest fish schools, but they also hunt individually. Dolphins search for prey primarily using echolocation, which is similar to sonar.
They emit clicking sounds and listen for the return echo to determine the location and shape of nearby items, including potential prey. Bottlenose dolphins also use sound for communication, including squeaks and whistles emitted from the blowhole and sounds emitted through body language, such as leaping from the water and slapping their tails on the water surface. Bottlenose dolphins can be found all times of the year in Jervis Bay.
