I understand that swedish has only one present tense, so there is no difference between "eats" and "is eating. The english version, however, has an error. I am not talking about the probability of a crab eating a strawberry :) There should be an option for "is eating the strawbery". "A crab eats the strawberry" means that a crab has a habbit of eating this very particular strawberry on regular basis. It would have to be a really huge and never rotting strawberry.
