Clownfish work together to make a house a home

Background:

This was a sneak peak for the TV series Blue Planet II, a nature documentary narrated by David Attenborough and airing on the BBC:

In the clip, a male clownfish spots a coconut shell resting on the ocean floor, several feet from his anemone home. Giving it a nudge, he tries to grip on to the shell's fibres with his mouth, to no avail. Spotting him struggling, his female mate joins in along with their young to help roll it back to their sea-bed plot. The male adjusts the anemone tentacles and tucks in the coconut shell, allowing a safe nursery for the female to lay her eggs.
