Wouldn't a shark that runs on electricity have a problem in salt water? That's the hold up for my frikken laser beams!

I found the biggest part about this to be that it tosses another massive hole into the argument of global warming alarmists that claim the world cannot adapt to the speed of the warming (and for whatever reason refuse to accept historical proofs of even better adaptability).

The mating of the local Australian black-tip shark with its global counterpart, the common black-tip, was an unprecedented discovery with implications for the entire shark world, said lead researcher Jess Morgan.

"It's very surprising because no one's ever seen shark hybrids before

Wait a minute, a sub-species of black-tip shark mated with a "common" black tip shark and the offspring
is a "hybrid"?

I'll start worrying when sharks start mating with mosquitoes.

Sounds like a misnomer to me. If a black and white human couple produced offspring you would not call them "hybrids".

Interesting it would happen with sharks though. I think they are, after a crustacean species named Nautilus, the longest lived species on Earth. Usually you associate rapid adaptation with tiny stuff like bacteria, viruses etc.

But the only difference the child may have is skin colour. These sharks are gaining the ability swim a far greater range and probably have enough unique characteristics to warrant being called hybrids. Kind of like how the Polar/Grizzly bear offspring are called hybrids.

I guess any person mating with another person from another country creates "hybrids" too...

It kinda makes me wonder why the "common" black-tip is called that, the Australian black-tip is called that, and why they are both black-tips? What is their relation? Who's gramma cheated with whose grampa? Who's the hybrid in the first place? Is it cousins mating here???
