see this big, ferocious animal and she's going to come out and interact with you. you can play with her, stroke her, and, of course, feed her. >> after all, emma is known for her hardy appetite. in fact, she's adored throughout the dive community in thailand, and tour groups flock to see emma in her beautiful feeding grounds. >> all the dive guides used to take food down for her, sausage, bacon, leftovers from breakfast. we've fed the moray many, many times, maybe become a little bit complaisant. she was more like a friendly dog than a ferocious animal to us. >> matt plays her, teasing emma with his bag of sausages and breakfast food. the moray eel seems to enjoy the games. here she nuzzles against matt's hands and passes back and forth like a playful pet. matt's friend captures the whole thing on camera. >> when we would approach them, they would swim out and you could have a little play. she would nestle under your arm and you could stroke her. and of course when she started losing interest, that's when the food would come out, just to tempt her for a little longer play with a moray eel.
