In the latest episode of Ze Frank's True Facts series, he learn about five very strange species of eel. There are more than a thousand species of eel, so you probably haven't seen anywhere near most of them. Still, all eels are fish, but not like other fish. or example, the ribbon eel is born male -all of them. But you can't reproduce like that, so some turn into females as they mature. Moray eels have a second set of jaws like a xenomorph, and some can hunt prey on land. The pelican eel is called that because of its terrifying mouth. American eels and European eels don't even have sex organs until late in life, when they grow a pair (literally), and meet up to have an orgy in the ocean, right before they die. But those facts are just a tiny taste of the weird things you will learn about eels. Expect double entendres, snide remarks, and juvenile humor, as always.
