Without water, a human can only survive for about 100 hours. But there’s a creature so resilient that it can go without it for decades. This 1-millimeter animal can survive both the hottest and coldest environments on earth, and can even withstand high levels of radiation. Thomas Boothby introduces us to the tardigrade, one of the toughest creatures on Earth.

Let's do a fun science experiment! We're going to learn how to find Water Bears. Join me to learn about these awesome microscopic creatures! Tardigrades, also known as Water Bears, are adorable microscopic animals. They look like caterpillars and walk like bears. There are over 1000 species and they can be found in almost any habitat. That's a lot of Tardigrades! Water Bears are also known to be pretty tough. Surviving extreme heat, pressure, and radiation is a walk in the park for them. So they should be able to handle New York right? Well let’s find out!

While both of these animals are capable of doing some serious damage to the human body, they deliver their dangerous toxins in different ways. Rose Eveleth sheds light on the distinction between poison and venom (and why you shouldn't treat either one like you've seen in the movies). Lesson by Rose Eveleth, animation by TED-Ed.

Intriguingly, many parasites have evolved the ability to manipulate the behavior of their hosts to improve their own survival -- sometimes even by direct brain control. Jaap de Roode details a few parasites that can really mess with the mind. Lesson by Jaap de Roode, animation by Andrew Foerster.

Check out Bill Schutt's "Cannibalism: A Perfectly Natural History": http://bit.ly/2HLWjrU View full lesson: https://ed.ted.com/lessons/cannibalism-in-the-animal-kingdom-bill-schutt Until recently, scientists thought cannibalism was a rare response to starvation or other extreme stress. Well-known cannibals like the praying mantis and black widow were considered bizarre exceptions. But now, we know they more or less represent the rule. Bill Schutt shows how cannibalism can promote the survival of a species by reducing competition, culling the weak, and bolstering the strong. Lesson by Bill Schutt, animation by Compote Collective.
