southern Australian bottlenose dolphin

The southern Australian bottlenose dolphin, also known as the Burrunan dolphin, is a marine mammal found in the waters off Australia's southern and southeastern coasts. Some researchers consider it a distinct species, while others classify it as a subspecies of the Indian Ocean bottlenose dolphin. These dolphins typically reach lengths of 2.5 to 3 meters (8 to 10 feet) and weigh between 135 and 300 kg (300 to 650 pounds), with males generally being larger than females.1

Bottlenose dolphins, in general, are known for their intelligence and ability to communicate through sounds and ultrasonic pulses. They possess remarkable social memories, capable of recognizing individual dolphins they haven't seen for decades. Some studies also suggest a degree of self-awareness, as they have been observed recognizing their reflections. Additionally, some bottlenose dolphins have been seen to self-medicate by rubbing against specific corals and sponges to obtain medicinal compounds.12
