The scourge of the Gulf of Mexico, the lionfish are such a menace, destroying the delicate balance of the underwater ecosystem.
What makes lionfish so dangerous is that they reproduce like crazy, and they have no predators. If the lion is the king of the jungle, the lionfish is the aquatic version.
When you see a lot of lionfish, you don't see anything else. Lionfish are not poisonous but are venomous; they're a flaky white fish that people enjoy eating – but beware of their spines. One sting and your hand will swell up to three times its size.
Lionfish can reproduce by age one. That's a remarkably young age of sexual maturity. Other reef fish don't reproduce until five to eight years. They spawn every four days, and an average female can spawn more than 3 million eggs a year.
