Social media user Frankie shared a video of the fish swimming to the surface, which gained over 75,000 views.
However, the story of the tiny fish with a black body and a mouth full of fangs has captured the hearts of TikTokers all over the world after they heard it died shortly after swimming to the surface.
The terrifying-looking black demon fish, that lurks underwater at depths between200 and 2,000 metres, was spotted by scientists at the surface exploring the waters off the coast of Tenerife last week.
'Emerging from the abyssal depths in vertical swimming, off just 2 km from the coast of Tenerife and during one of our pelagic shark research campaigns, @laiavlr spotted this creature on the surface,' Mr Boguna wrote.
Kaleigh, from Chicago , took to social media in floods of tears as she wondered if the fish was 'proud of herself'.
