TIL: Some Sharks Can Glow In The Dark | Today I Learned

one thing that maybe people don’t know
is that there are glow-in-the-dark
sharks these are sharks that have
compounds in their skin that take the
blue ocean light and make other colors
for them it’s like having a secret mode
of communication like a covert channel
unlike humans they only see blue and
green so to them this fluorescence that
they’re creating at depth is sticking
out like a sore thumb they can easily
find each other
you could take all 270,000 metric tons
of nuclear waste that exists worldwide
and you can turn that into enough
electricity to power the entire world
for 72 years
