Common dolphins can be found in False Bay all year round and are often seen on our dives and boat charters between January and July when they follow schools of their favourite food – small fish such as anchovies and mackrel.

Here’s some interesting facts about common dolphins that you might not have known…

  1. There are two species of common dolphin – the short-beaked and the long-beaked common dolphin.
  2. The common dolphins we see in False Bay are the long-beaked species.
  3. Both common dolphin species range between 1.9m and 2.5m in length and, on average, can weigh between 80 and 150kg.
  4. Male common dolphins are larger and heavier than the female common dolphins.

  13. Common dolphins often work together to herd schools of fish together and can be seen accompanied by diving birds and feeding whales. They can eat about 5% of their body weight every day.
  14. Common dolphins are very sociable and thrive on the connections they have with each other. Vocalizations include whistling, whining and clicking. Their language tends to vary from pod to pod.
  15. The major threats facing common dolphins are human related, the largest being metal and plastic pollutants and thousands have been caught by accident in industrial trawler nets as bycatch.
