It's not OK to touch bioluminescence light when it is caused by algae blooms.
Some bioluminescence algae is harmless but others can be toxic and cause illness and or skin irritation.
Also disturbing of the organisms which cause the bioluminescence can also harm them and disrupt the natural ecosystem.
Not all forms of bioluminescent algae are harmful, although some species of bioluminescent algae can produce toxins which are dangerous to animals and humans.
And even if the bioluminescence is not cause by a toxic species, coming into direct contact with the bioluminescence algae can still cause skin irritation and even other adverse reactions.
Touching or disturbing of the organisms which create the bioluminescence can also disrupt the natural behavior of the organisms and even harm them.
Bioluminescence is a beautiful natural phenomenon, although it's best to observe it from a distance and avoid touching it or disturbing the organisms.
And in some bioluminescent bays, swimming is also restricted or even prohibited to protect the delicate ecosystem and the organisms which produce the light.
