It's been my go-to weeknight dinner for over 20 years, and I never skip this one ingredient.

Pufferfish release a toxin when they puff out that is meant to impair the attacker. This doesn’t work on Dolphins in the same way. It gets them high. So they purposely inflate them and pass them around to their dolphin friends for fun.

You'd think at least 184 million years of evolution on entirely separate continents would be enough to make two species of fish sexually incompatible. That was the assumption scientists in Hungary were going on when they placed sperm from an American paddlefish near eggs from a Russian sturgeon in the lab.
