This pair of fish may appear to be engaged in a passionate seabed snog, but there is something far more serious going on.
The couple was filmed sucking each other’s faces in what appeared to be a very wet kiss off the coast of Lembeh, Indonesia.
However, the pair of Two Spot Wrasses filmed by Japanese diver Atsushi Sadaki, 59, were engaged in a fierce territorial battle.
The business design consultant said: ‘The fish look like they are absolutely crazy about kissing.
‘But this is not a beautiful love story. In fact it is a fight for territory.
‘Fighting scenes like this are rather rare.
‘I watch these fish when I dive, and I have over 1,000 dives under my belt, and it is the first time I saw something like this.
‘It typically happens more in the mating season. They were fighting for a long time however, and I found it fascinating to watch.’
