This cuttlefish male diligently guards his mate as she lays her eggs near the ocean bed.
Video captured off the island of Malapascua in the Philippines shows the female cuttlefish – the larger of the two – depositing the eggs from sacs near her mouth opening.
As is common with cuttlefish, the male guards the female until the process is over, in this case placing a reassuring tentacle on the mother's back.
Cuttlefish, who are cephalopods, can be found in oceans across the globe.
They are able to change the texture and colour of their skin to hunt and hide from predators.
The footage was captured on April 27, 2017.
