Golfo Aranci is one of the best places in Sardinia for dolphin sightings, particularly of the species Tursiops truncatus, better known as the bottlenose dolphin.
But why are dolphins found right here? Let's find out together.
Why do dolphins live in Golfo Aranci?
The dolphins of Golfo Aranci prefer this area for several reasons:
- Food richness: The presence of fish farms in the area is a significant attraction for bottlenose dolphins. These facilities offer an easily accessible food source, making the area particularly attractive to dolphins.
- Protected environment: The conformation of the coastline and the relatively shallow waters provide a safe environment, especially for females with their young.
- Water temperature: Sardinia's mild climate ensures optimal conditions for the survival of the species throughout the year.
- Less predators: Compared to open waters, Golfo Aranci's area offers more protection from the natural predators of dolphins, such as large sharks.
Characteristics of bottlenose dolphins Tursiops truncatus
Bottlenose dolphins are among the best known and most studied cetaceans, thanks to their high intelligence and ability to interact with humans. Here are some of their main characteristics:
- They are mammals, not fish : dolphins breathe through their lungs and have to surface to inhale air through the blowhole.
- They live in groups: They usually form flocks of 2 to 10 individuals, with females and young remaining together, while males tend to be more solitary.
- Long-lived and fast: They can live more than 50 years and reach speeds of 30 km/h.
- Sophisticated communication: They use sounds such as clicks for echolocation and whistles for communication between individuals.
The reproduction and growth of the young
A fascinating aspect of dolphins' lives is their reproduction. Gestation lasts about 12 months and, once born, the young remain with their mother for several years. Suckling lasts about 18 months, but the pups stay with their mother until they are 4-6 years old, learning to swim, hunt and socialise.

Frequently asked questions about the dolphins of Golfo Aranci
Why do dolphins often come to the surface?
Dolphins have lungs and breathe through the blowhole. They have to emerge regularly to inhale air before diving again.
How long can they hold their breath?
They can stay submerged for four to eight minutes and reach depths of over 200 metres.
How do dolphins communicate with each other?
They use two main types of sounds: clicks, used to detect obstacles and prey, and whistles, used for communication between individuals.
Do dolphins sleep?
Yes, but in a special way: only one half of their brain rests at a time, allowing them to remain alert and breathing.
What do dolphins eat?
Mainly fish, squid and crayfish. They catch their prey with their teeth, but do not chew it.
How do researchers recognise dolphins?
Thanks to the shape and distinctive features of the dorsal fin, as well as the analysis of sounds recorded with hydrophones.
What are the main threats to dolphins?
Pollution, intensive fishing, fishing nets and collisions with boats are the main threats to their survival.
