Male Amazon river dolphins swim to the surface, roll over, and pee straight up into the air, and they don’t do it for the ladies.

A hiker and her dog had a beautiful experience in British Columbia when they came across a pod of dolphins putting on quite a show.

A whale-watching boat spotted a super pod of more than 1,500 Risso’s dolphins off the coast of California. Watch drone footage here.

“Oh to be an Amazon River dolphin gently harassing a large black caiman in a beautiful blackwater river”—watch the humorous interaction here.

An open-ocean paddleboarder came across a pod of Risso’s dolphins that appeared to glow underwater. Watch his reaction here.

A small pod of dolphins became very curious about a sea turtle as they surrounded it and circled it. See the interaction here.

Nature can be brutal, especially predator-prey interactions. Watch orcas hunt smaller dolphins by head-butting them mid-air here.
