i honestly didnt see anything wrong with forcing the regurge. if you wantto see what an animals been eating to learn more about it ten thats wha you must do.
the prpose it served was that they figured out what the snake had been eating and where it was hanging around.
i dont believe they were JUST focusing on only one thing. they were studying the habitats and animals in it. they're main reason to be there was to see the Tiomon pit viper but they were also there for other things.
