If you haven't already seen it, take a look at the dolphin video on the BBC Wales nature portal currently.
It's an amazing clip showing bottle nose dolphins playing around with jellyfish, smashing them up into the air with their tails. It can't have been much fun for the jellyfish though!
The footage was filmed off Tremadaog Bay, North West Wales.
I had a text from family yesterday (15 October, 2009) staying at Whitesands beach down in Pembrokeshire saying they had just seen two porpoises, a seal pup and what they thought were killer whales (orcas) off the coast so I'd love to hear from you if you can verify this sighting!
We did have sightings of orcas back in June off Ramsey Island so anything is possible.
