30 Days Wild 2020 – Day Eight.


twt-30-days-wild_countdown_08Day 8: Today is World Oceans Day, so in honour of this campaign, today’s Close up Monday will be of bottle-nosed dolphins. I’ll admit that marine wildlife is one aspect of my knowledge that isn’t particularly strong. So I am going to use today as a platform to further my understanding around this subject.

What’s your favourite ocean inhabitant?

The bottle-nosed dolphin is probably the best known of all UK whale and dolphin species (cetaceans). While reading the summer edition of the RSPB’s Nature’s Home magazine, I was surprised to discover that up to 28 of these aquatic mammals have been seen around UK shores.

Some facts on bottle-nosed dolphins:

  • UK bottle-nosed dolphins are the biggest in the world, their larger bodies help with the cold of our waters
  • They can live up to 50 years of age
  • Are carnivore and eat other fish and crustaceans
  • They have good eyesight and their eyes can move independently of each other
  • They can’t detect colour
  • Highly sociable and live within pods of up to 15 members
  • Research has shown that dolphins have names or a unique whistle to identify them from other dolphins
  • Like bats they use echolocation for finding food and navigation
  • Their stomachs consist of three chambers, one to store, one to digest and one to excrete
  • They sleep by shutting one side of their brain and the opposing eye
  • ‘Breaching’ or jumping out of water is a way of cleaning parasites off their bodies
  • As a mammal they are warm blooded and need to breathe through a blow hole

Moray Firth dolphins

Bottle-nosed dolphins enjoy the safety of sheltered bays and can be seen often at RSPB Bempton Cliffs, Moray Firth in Scotland, Cornwall and Dorset.

Have you seen any bottle-nosed dolphins around the coast of the UK? Have you seen any other cetaceans?

Thanks for reading, and stay wild!
