Around the tip of a terdigrade's mouth are small bumps that we think act like little sensors. And when those bumps make contact with a rotifer, out pops the tardigrade's stylet, a little needle that pokes out from the tubular mouth opening. That stylet pokes into the rotifer, and from there the tardigrade uses a circular structure called a pharynx in its head to create strong suction. And then, the stylet goes from functioning as a needle to functioning as a portable, built-in straw that lets the tardigrade suck out the inside of its prey. You can see some of the bodily fluid leaving the rotifer as the terdigrade's stylet pumps away like a beating heart. And when she is done, the rotifer remains, like an empty coffee cup.
