Blue-Ringed Octopus
To defend themselves, most octopi use ink, but the blue-ringed octopus sprays a poison that can kill up to 26 people in a matter of seconds with just one squirt. Its blue rings on its body help to identify this marine creature, despite its intimidating size. Tetrodotoxin, a lethal toxin also found in pufferfish, would be injected if you held it in your palm (please don’t!). When it comes to these killers, you’re unlikely to come across them because they tend to hide in dark crevices that are about 165 feet deep.
Alligator
However, alligators don’t kill as many people as you might think. There have been only 25 fatal alligator attacks in Florida since 1948, according to the Florida Fish and Wildlife Commission, despite the state’s average of seven alligator attacks per year. Don’t feed an alligator if you see one. Furthermore, it teaches them to associate people with food, which is illegal. That is not acceptable!
