'It's a tool that biologists use to study how cells or tissues work within the body of an animal,' Srivastava said. Transgenesis is when scientists introduce something into the genome of an organism that is not normally part of that genome. The scientific way to say this is that the worms are now transgenic. Now, worms that glow in the dark with UV light may sound gimmicky, but the researchers of the study explain it's far from it. The work is described in a new paper in Developmental Cell and is led by Mansi Srivastava, a professor of organismic and evolutionary biology at Harvard who first collected these worms in 2010 to use as a model organism. Now, a team of researchers is taking the study of these worms to the next level by making them glow in the dark. Its why scientists started studying this Tic Tac sized worm in order to learn how it pulls off this amazing feat. Perhaps surprisingly, there are no known light-producing plants – only bioluminescent fungi.Put simply: Three-banded panther worms are one of the greatest of all time when it comes to whole-body regeneration. A number of terrestrial creatures have also evolved to glow, but fish are the only bioluminescent vertebrates. In fact, making light has proven to be such a useful trait that it has evolved independently at least 40 times.īioluminescence is most common in the oceans – where in the deep it’s the only form of light – and according to Nature journal, an incredible 76% of ocean species are bioluminescent to some degree.

Animals on this list and produce light and use bioluminescence to: Whilst glowing animals may seem other-worldly, there are a range of practical reasons animals have evolved this special power. So bioluminescent creatures are simply animals that produce their own light.

This light is created by the organism either through a series of chemical reactions (typically a substance called luciferin reacts with oxygen as a chemical reaction to release energy in the form of light), or by a form of glowing bacteria that the animal hosts. The term ‘bioluminescence’ refers to the production of light by living organisms which is emitted from their body. The world is a wonderful place, and nature’s magic is no more in evidence than when it comes to bioluminescent animals – animals that can actually glow in the dark! What is a ‘bioluminescent animal’?
