A recent video shows the incredible moment a mother humpback whale and mother dolphin bring their families together.
The footage, which was taken from a drone, shows a humpback whale and her calf swimming with a mother dolphin and her calf. Though the humpback pair dwarfs the dolphins, the two families glide peacefully next to each other.
It seems to be a conscious decision on the part of the mothers to bring their little families close together; the humpbacks follow closely behind the relaxed dolphins, and at times the mother humpback appears to be just inches away from the dolphin mother's tail.
Despite their size difference, humpbacks and dolphins have formed similar cross-species friendships on several occasions - they've even been spotted playing with each other. You can watch the encounter below.
