Don’t forget the bats. Bat species do well flying with teeth capable of dealing with diets from invertebrates to small birds and mammals.

and when they become scared, when it becomes dangerous for them to defend it, it can go very quickly."

>> hello everyone,
>> the question, why birds don't have teeth, has occupied many scientists through the years, and has generated a variety of hypotheses. But a new idea has been proposed that may explain both why birds don't have teeth and why they underwent such an explosive radiation after the extinction of all non-avian dinosaurs. The hypothesis needs more work, but it's a paradigm shift that will trigger a lot of new research.
