That's a good point with the crocodile I thought the same... But no not berries I don't think I said berries but everybody keeps saying stuff about berries lol now I'm sure they are capable of eating berries I was thinking it would be used to crack hard fruit such as coconut or melons... Now with that being said u don't know what vegetation grows on the home planet but however I never banked on a vegan diet just saying it could make sense now I'd bet they where omnivores considering the space travel and having to adapt to different diets on different planets
