Jurassic Park Wiki
"Okay folks, let's see if she's still hungry after already eating today. She's a little shy so be nice and give her a hand when she comes out."

Sarah,[1] commonly known as the Mosasaurus Announcer, was a woman working at Jurassic World's Mosasaurus Feeding Show. She spoke through a microphone and announced when the Mosasaurus was going to be fed. She also reeled off what the Mosasaurus would likely have eaten, including turtles, large fish and even smaller mosasaurs. Sarah escaped getting drenched, unlike most of the audience, when the Mosasaurus was fed a shark and then caused a huge splash.

It is unknown what happened to her when the pterosaurs attacked Main Street.[2]
