A YouTube sensation has raised a lot of questions about cruelty to animals, but scientists say there's no need to be concerned.

The video shows a dancing squid dish at a Japanese restaurant.

Scientists say even though the squid is brain dead, most of the tissue is still alive and when soy sauce is poured on top of it the sodium in the sauce triggers a reaction in the squid's suckers.

According to scientists, since the squid no longer has use of its brain, it can't feel any pain.
