How To Teach A Sea Lion Who's Fussy About Grammar

"When it comes to sentence structure, Rocky, a sea lion, was a stickler."

"'It really mattered to her, what's going to be the direct and indirect object,' says Kathy Streeter, an animal trainer."

"For Sierra, it isn't the grammar that interests her. It's the vocalizations. This California sea lion loves experimenting with her vocal range, and she hates being interrupted."

"More than 1 million people visit the New England Aquarium in Boston each year. Before walking through the front door, they watch Atlantic harbor seals play. Inside, visitors watch sea lions cruise around the open-air pool."

"What these visitors may not know is that the aquarium's 10 seals and two sea lions go to school each day; Streeter is one of their teachers."
