This is the moment a Yellow Headed Jawfish swallows and spits back out his own eggs.
The male carries the eggs in its mouth until they hatch, aerating and rotating the eggs in a really fast motion as the female tentatively watches out for him.
The footage was captured by David Buky, 36, in the Grand Cayman, British Virgin Islands.
The species of fish is native to the coral reefs in the Carribean Sea and is found at depths of 40 metres.
The head and upper body are a light but brilliant yellow colour that slowly fades into a pearlescent blue.
Often it can typically be seen with only its head and upper section of its body protruding from its burrow.
