The best videos we've seen this week
1. Basking shark in Ireland
Early summer is when basking sharks start to arrive in Ireland and the UK. This video filmed near Cork uses a camera on a mini drone to film a basking shark from above. Just look at it compared to the size of the boat!
2. 'Stingray' attacks swimmer
This video was revealed to be a hoax after it was picked up by The Sydney Morning Herald and angered a few conservationists. The 'stingray' is actually the shadow of a kite, being flown by the guy's daughter. So the whole thing is a dad joke - and just in time for father's day!
3. Killer whales
Lovely footage of orcas underwater - and playing at the surface.
